General Description
The MAX5363/MAX5364/MAX5365 low-cost, 6-bit digital-
to-analog converters (DACs) in miniature 6-pin SOT23
packages have a simple 3-wire, SPI/QSPI/
MICROWIRE-compatible serial interface that operates
up to 10MHz. The MAX5363 has an internal +2V refer-
ence and operates from a +2.7V to +3.6V supply. The
MAX5364 has an internal +4V reference and operates
from a +4.5V to +5.5V supply. The MAX5365 operates
over the full +2.7 to +5.5V supply range and has an
internal reference equal to 0.9 ✕VDD.
The MAX5363/MAX5364/MAX5365 require an extremely
low supply current of only 150µA (typ) and provide a
buffered voltage output. These devices power up at
zero code and remain there until a new code is written
to the DAC registers. This provides additional safety for
applications that drive valves or other transducers that
need to be off on power-up. The MAX5363/MAX5364/
MAX5365 include a 1µA, low-power shutdown mode
that features software-selectable output loads of 1kΩ,
100kΩ, or 1MΩto ground.

Detailed Description
The MAX5363/MAX5364/MAX5365 voltage-output, 6-bit
DACs offer full 6-bit performance with less than 1LSB
integral nonlinearity error and less than 1LSB differen-
tial nonlinearity error, ensuring monotonic performance.
The devices use a simple 3-wire, SPI/QSPI/ MICROWIRE-
compatible serial interface that operates up to 10MHz.
The MAX5363/MAX5364/MAX5365 include an internal
reference, an output buffer, and three low-current shut-
down modes, making these devices ideal for low-
power, highly integrated applications. Figure 1 shows
the devices’ functional diagram.
Analog Section
The MAX5363/MAX5364MAX5365 employ a current-
steering DAC topology as shown in Figure 2. At the
core of the DAC is a reference voltage-to-current con-
verter (V/I) that generates a reference current. This current
is mirrored to 63 equally weighted current sources.
DAC switches control the outputs of these current mirrors
so that only the desired fraction of the total current-mirror
currents is steered to the DAC output. The current is
then converted to a voltage across a resistor, and this
voltage is buffered by the output buffer amplifier.
Output Voltage
Table 1 shows the relationship between the DAC code
and the analog output voltage. The 6-bit DAC code is
binary unipolar with 1LSB = (VREF/64). The MAX5363/
MAX5364 have a full-scale output voltage of (+2V - 1LSB)
and (+4V - 1LSB), respectively, set by the internal refer-
ences. The MAX5365 has a full-scale output voltage of
(0.9 ✕VDD - 1LSB).
Output Buffer
The DAC voltage output is an internally buffered unity-
gain follower that slews up to ±0.4V/µs. The output can
swing from 0 to full scale. With a 1/4FS to 3/4FS output
transition, the amplifier outputs typically settle to
1/2LSB in less than 5µs when loaded with 10kΩin par-
allel with 50pF. The buffer amplifiers are stable with any

combination of resistive loads >10kΩand capacitive

Power-On Reset
The MAX5363/MAX5364/MAX5365 have a power-on
reset circuit to set the DAC’s output to 0 when VDD is
first applied or when VDD dips below 1.7V (typ). This
ensures that unwanted DAC output voltages will not
occur immediately following a system startup, such as
after a loss of power. The output glitch on startup is typ-
ically less than 50mV.
Shutdown Mode
The MAX5363/MAX5364/MAX5365 include three soft-
ware-controlled shutdown modes that reduce the supply
current to <1µA. All internal circuitry is disabled, and a
known impedance is placed from OUT to GND to
ensure 0V while in shutdown. Table 2 details the three
shutdown modes of operation.
Digital Section
3-Wire Serial Interface
The MAX5363/MAX5364/MAX5365s’ digital interface is
a standard 3-wire connection compatible with
SPI/QSPI/MICROWIRE interfaces. The chip-select input
(CS) frames the serial data loading at the data-input pin
(DIN). Immediately following CS’s high-to-low transition,
the data is shifted synchronously and latched into the
input register on the rising edge of the serial clock input
(SCLK). After 16 bits have been loaded into the serial

input register, it transfers its contents to the DAC latch
on CS’s low-to-high transition (Figure 3). Note that if CS
is not kept low during the entire 16 SCLK cycles, data
will be corrupted. In this case, reload the DAC latch
with a new 16-bit word. The serial clock (SCLK) can
idle either high or low between transitions. Figure 4
shows the complete 3-wire serial interface transmission.
Table 3 lists serial interface mapping.
Applications Information
Device Powered by an External Reference
Since the MAX5365 generates an output voltage pro-
portional to VDD, a noisy power supply will affect the
accuracy of the on-board reference, thereby affecting
the overall accuracy of the DAC. The circuit in Figure 5
rejects this power-supply noise by powering the device
directly with a precision voltage reference, improving
overall system accuracy. The MAX6103 (+3V, 75ppm)
or the MAX6105 (+5V, 75ppm) precision voltage refer-
ences are ideal choices due to the low power require-
ments of the MAX5365. This solution is also useful
when the required full-scale output voltage is different
from the available supply voltages.
Digital Inputs and Interface Logic
The digital interface for the 6-bit DAC is based on a
3-wire standard that is compatible with SPI, QSPI, and
MICROWIRE interfaces. The three digital inputs (CS, DIN,
and SCLK) load the digital input serially into the DAC.
All of the digital inputs include Schmitt-trigger buffers to
accept slow-transition interfaces. This means that opto-
couplers can interface directly to the MAX5363/
MAX5364/MAX5365 without additional external logic.
The digital inputs are compatible with CMOS logic levels
and can be driven with voltages up to +5.5V regardless
of the supply voltage.
Power-Supply Bypassing and Layout
Careful PC board layout is important for best system
performance. To reduce crosstalk and noise injection,
keep analog and digital signals separate. To ensure
that the ground return from GND to the supply ground
is short and low impedance, a ground plane is recom-
mended. Bypass VDD with a 0.1µF to ground as close
as possible to the device. If the supply is excessively
noisy, connect a 10Ωresistor in series with the supply
and VDD and add additional capacitance.
