Description
The MCP3202 is a successive approximation 12-bit
analog-to-digital (A/D) converter with on-board sample
and hold circuitry.
The MCP3202 is programmable to provide a single
pseudo-differential input pair or dual single-ended
inputs. Differential Nonlinearity (DNL) is specified at
±1 LSB, and Integral Nonlinearity (INL) is offered in
±1 LSB (MCP3202-B) and ±2 LSB (MCP3202-C)
versions.
Communication with the device is done using a simple
serial interface compatible with the SPI protocol. The
device is capable of conversion rates of up to 100 ksps
at 5V and 50 ksps at 2.7V.
The MCP3202 operates over a broad voltage range,
2.7V to 5.5V. Low-current design permits operation with
typical standby and active currents of only 500 nA and
375 µA, respectively.
The MCP3202 is offered in 8-pin MSOP, PDIP, TSSOP
and 150 mil SOIC packages.

MCP3202
4.0 DEVICE OPERATION
The MCP3202 A/D converter employs a conventional
SAR architecture. With this architecture, a sample is
acquired on an internal sample/hold capacitor for
1.5 clock cycles starting on the second rising edge of
the serial clock after the start bit has been received.
Following this sample time, the input switch of the con-
verter opens and the device uses the collected charge
on the internal sample and hold capacitor to produce a
serial 12-bit digital output code.
Conversion rates of 100 ksps are possible on the
MCP3202. See Section 6.2 “Maintaining Minimum
Clock Speed” for information on minimum clock rates.
Communication with the device is done using a 3-wire
SPI-compatible interface.
4.1 Analog Inputs
The MCP3202 device offers the choice of using the
analog input channels configured as two single-ended
inputs or a single pseudo-differential input. Configura-
tion is done as part of the serial command before each
conversion begins. When used in the pseudo-differen-
tial mode, CH0 and CH1 are programmed as the IN+
and IN- inputs as part of the command string transmit-
ted to the device. The IN+ input can range from IN- to
VREF (VDD + IN-). The IN- input is limited to ±100 mV
from the VSS rail. The IN- input can be used to cancel
small signal common-mode noise which is present on
both the IN+ and IN- inputs.
For the A/D converter to meet specification, the charge
holding capacitor (CSAMPLE) must be given enough
time to acquire a 12-bit accurate voltage level during
the 1.5 clock cycle sampling period. The analog input
model is shown in Figure 4-1.
In this diagram, it is shown that the source impedance
(RS) adds to the internal sampling switch (RSS) imped-
ance, directly affecting the time that is required to
charge the capacitor, CSAMPLE. Consequently, larger
source impedances increase the offset, gain, and
integral linearity errors of the conversion.
Ideally, the impedance of the signal source should be
near zero. This is achievable with an operational
amplifier such as the MCP601 which has a closed loop
output impedance of tens of ohms. The adverse affects
of higher source impedances are shown in Figure 4-2.
When operating in the pseudo-differential mode, if the
voltage level of IN+ is equal to or less than IN-, the
resultant code will be 000h. If the voltage at IN+ is equal
to or greater than {[VDD+(IN-)] -1 LSB}, then the output
code will be FFFh. If the voltage level at IN- is more
than 1 LSB below VSS, then the voltage level at the IN+
input will have to go below VSS to see the 000h output
code. Conversely, if IN- is more than 1 LSB above VSS,
then the FFFh code will not be seen unless the IN+
input level goes above VDD level.
4.2 Digital Output Code
The digital output code produced by an A/D converter
is a function of the input signal and the reference volt-
age. For the MCP3202, VDD is used as the reference
voltage. As the VDD level is reduced, the LSB size is
reduced accordingly. The theoretical digital output code
produced by the A/D converter is shown below.

MCP3202
5.0 SERIAL COMMUNICATIONS
5.1 Overview
Communication with the MCP3202 is done using a
standard SPI-compatible serial interface. Initiating
communication with the device is done by bringing the
CS line low. See Figure 5-1. If the device was powered
up with the CS pin low, it must be brought high and
back low to initiate communication. The first clock
received with CS low and DIN high will constitute a start
bit. The SGL/DIFF bit and the ODD/SIGN bit follow the
start bit and are used to select the input channel config-
uration. The SGL/DIFF is used to select Single-Ended
or Pseudo-Differential mode. The ODD/SIGN bit
selects which channel is used in Single-Ended mode,
and is used to determine polarity in Pseudo-Differential
mode. Following the ODD/SIGN bit, the MSBF bit is
transmitted to and is used to enable the LSB first format
for the device. If the MSBF bit is high, then the data will
come from the device in MSB first format and any fur-
ther clocks with CS low will cause the device to output
zeros. If the MSBF bit is low, then the device will output
the converted word LSB first after the word has been
transmitted in the MSB first format. See Figure 5-2.
Table 5-1 shows the configuration bits for the
MCP3202. The device will begin to sample the analog
input on the second rising edge of the clock, after the
start bit has been received. The sample period will end
on the falling edge of the third clock following the start
bit.
On the falling edge of the clock for the MSBF bit, the
device will output a low null bit. The next sequential
12 clocks will output the result of the conversion with
MSB first as shown in Figure 5-1. Data is always output
from the device on the falling edge of the clock. If all
12 data bits have been transmitted and the device con-
tinues to receive clocks while the CS is held low, (and
MSBF = 1), the device will output the conversion result
LSB first as shown in Figure 5-2. If more clocks are pro-
vided to the device while CS is still low (after the LSB
first data has been transmitted), the device will clock
out zeros indefinitely.
If necessary, it is possible to bring CS low and clock in
leading zeros on the DIN line before the start bit. This is
often done when dealing with microcontroller-based
SPI ports that must send 8 bits at a time. Refer to
Section 6.1 “Using the MCP3202 with Microcon-
troller (MCU) SPI Ports” for more details on using the
MCP3202 devices with hardware SPI ports.

MCP3202
6.0 APPLICATIONS INFORMATION
6.1 Using the MCP3202 with
Microcontroller (MCU) SPI Ports
With most microcontroller SPI ports, it is required to
send groups of eight bits. It is also required that the
microcontroller SPI port be configured to clock out data
on the falling edge of clock and latch data in on
the rising edge. Depending on how communication
routines are used, it is very possible that the number of
clocks required for communication will not be a multiple
of eight. Therefore, it may be necessary for the MCU to
send more clocks than are actually required. This is
usually done by sending ‘leading zeros’ before the start
bit, which are ignored by the device.
As an example, Figure 6-1 and Figure 6-2 show how
the MCP3202 can be interfaced to a MCU with a
hardware SPI port.
Figure 6-1 depicts the operation shown in SPI Mode
0,0, which requires that the SCLK from the MCU idles
in the ‘low’ state, while Figure 6-2 shows the similar
case of SPI Mode 1,1 where the clock idles in the ‘high’
state.
As shown in Figure 6-1, the first byte transmitted to the
A/D converter contains seven leading zeros before the
start bit. Arranging the leading zeros this way produces
the output 12 bits to fall in positions easily manipulated
by the MCU. The MSB is clocked out of the A/D con-
verter on the falling edge of clock number 12. After the
second eight clocks have been sent to the device, the
MCU receive buffer will contain three unknown bits (the
output is at high-impedance until the null bit is clocked
out), the null bit and the highest order four bits of the
conversion. After the third byte has been sent to the
device, the receive register will contain the lowest order
eight bits of the conversion results. Easier manipulation
of the converted data can be obtained by using this
method.

6.2 Maintaining Minimum Clock Speed
When the MCP3202 initiates the sample period, charge
is stored on the sample capacitor. When the sample
period is complete, the device converts one bit for each
clock that is received. It is important for the user to note
that a slow clock rate will allow charge to bleed off the
sample cap while the conversion is taking place. At
85°C (worst case condition), the part will maintain
proper charge on the sample capacitor for at least
1.2 ms after the sample period has ended. This means
that the time between the end of the sample period and
the time that all 12 data bits have been clocked out
must not exceed 1.2 ms (effective clock frequency of
10 kHz). Failure to meet this criteria may induce
linearity errors into the conversion outside the rated
specifications. It should be noted that during the entire
conversion cycle, the A/D converter does not require a
constant clock speed or duty cycle, as long as all timing
specifications are met.
6.3 Buffering/Filtering the Analog
Inputs
If the signal source for the A/D converter is not a low-
impedance source, it will have to be buffered or
inaccurate conversion results may occur. It is also
recommended that a filter be used to eliminate any
signals that may be aliased back into the conversion
results. This is illustrated in Figure 6-3 below where an
op amp is used to drive the analog input of the
MCP3202. This amplifier provides a low-impedance
output for the converter input and a low-pass filter,
which eliminates unwanted high frequency noise.
Low-pass (anti-aliasing) filters can be designed using
Microchip’s interactive FilterLab® software. FilterLab
will calculate capacitor and resistor values, as well as,
determine the number of poles that are required for the
application. For more information on filtering signals,
see the application note AN699 “Anti-Aliasing Analog
Filters for Data Acquisition Systems”.
FIGURE 6-3: The MCP601 Operational
Amplifier is used to implement a 2nd order anti-
aliasing filter for the signal being converted by
the MCP3202.
6.4 Layout Considerations
When laying out a printed circuit board for use with
analog components, care should be taken to reduce
noise wherever possible. A bypass capacitor should
always be used with this device and should be placed
as close as possible to the device pin. A bypass
capacitor value of 0.1 µF is recommended.
Digital and analog traces should be separated as much
as possible on the board and no traces should run
underneath the device or the bypass capacitor. Extra
precautions should be taken to keep traces with high
frequency signals (such as clock lines) as far as
possible from analog traces.
Use of an analog ground plane is recommended in
order to keep the ground potential the same for all
devices on the board. Providing VDD connections to
devices in a “star” configuration can also reduce noise
by eliminating current return paths and associated
errors. See Figure 6-4. For more information on layout
tips when using A/D converters, refer to AN688 Layout
Tips for 12-Bit A/D Converter Applications(DS00688).

Note the following details of the code protection feature on Microchip devices:
Microchip products meet the specification contained in their particular Microchip Data Sheet.
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
Microchip is willing to work with the customer who is concerned about the integrity of their code.
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Microchip received ISO/TS-16949:2009 certification for its worldwide
headquarters, design and wafer fabrication facilities in Chandler and
Tempe, Arizona; Gresham, Oregon and design centers in California
and India. The Company’s quality system processes and procedures
are for its PIC® MCUs and dsPIC® DSCs, KEELOQ® code hopping
devices, Serial EEPROMs, microperipherals, nonvolatile memory and
analog products. In addition, Microchip’s quality system for the design
and manufacture of development systems is ISO 9001:2000 certified.
