DESCRIPTION

The demo board for the TS1001 is a completely

assembled and tested circuit board that can be used

for evaluating the TS1001. The TS1001 is the first

0.8V/0.6µA, precision CMOS operatio nal amplifier in

the industry. The TS1001 exhibits an offset voltage o f

0.5mV, a typical input bias current of 25pA, and a rail-

to-rail input and output stages. The TS1 001 can

operate from single-supply voltages from 0.65V to

2.5V.

The TS1001 is fully specified at V

= 0.8V and over

the industrial temperature range (-40°C to +85 °C). It

is available in a PCB-space saving 5-lead SC70

surface-mount package.

Description

The TS1001 demo board provides two

configurations for evaluating the TS100 1 operational

amplifier in one single PCB board, namely a non-

inverting configuration located on the left-hand side of

the board and an inverting configuration located on

the right-hand side of the board. In both cases, the

input to each circuit is AC-coupled. The demo board

provides a re-biasing scheme at one-half the power

supply or V

/2 for the inverting configuration and at

/4 for the non-inverting configuration.

The TS1001 demo board provides a dedicate d power

supply for the non-inverting circuit and a dedicated

power supply for the inverting circuit. This provides

the user the flexibility of evaluating one circuit at a

time or both at the same time.

In both the non-inverting and the inverting

configuration, the AC-coupling capacitor creates a

high pass filter. The resulting cut-off frequency, f

, is

given as:

In the non-inverting circuit, R=R5=1M Ω and

C=C5=0.1µF. In the inverting case, R=R10=1MΩ and

C=C1=0.1µF. In both cases, these component values

generate a high-pass cut-off frequen cy of 1.6Hz.

Default Configurations

Non-Inverting configuration

In the non-inverting configuration, the circuit’s transfer

function is given by the following equation:

With R4=2MΩ and R3=2MΩ the circuit signal gain is

2 with a circuit bandwidth of 2kHz. This results in an

overall circuit bandwidth range of 1.6Hz to 2kHz.

Inverting configuration

In an inverting configuration, the circuit’s transfer

function is given by the following equation:

In this case, R6=1MΩ and R10=1MΩ. This results in

a signal gain of -1 with a circuit bandwidth of 2kHz

and an overall circuit bandwidth range of 1.6Hz to

2kHz.

Non-Inverting Configuration

In order to evaluate the TS1001 operational amplifier

in the non-inverting configuration, the following steps

are to be performed:

1) Before connecting the DC power supply to the

demo board power test points, turn on the power

supply and set the DC voltage to 2.5V and then

turn it off.

2) Set the function generator frequency to 500Hz

and output level with a V

= 1.35V and a V

1.15V. This sets the input signal swing to

200mV

, centered at 1.25V.

3) In order to monitor the input and output signal,

select two channels on the oscilloscope and set

the vertical voltage scale and the vertical position

on each channel to 100mV/DIV and -1.2 5V,

respectively. Set the horizontal time scale to

500µs/DIV.

4) Connect the positive terminal of the DC power

supply to TP8 and the ground terminal to TP1.

For all other connections, please refer to Table 1.

5) Connect the signal output of the function

generator to TP6 and the ground terminal to

TP10.

6) To monitor the input, connect the signal terminal

of one of the oscilloscope probes to TP6 and the

ground terminal to TP10. To monitor the output,

use the second probe to connect the signal

terminal to TP7 and the ground terminal to TP11.

7) Turn on the power supply and che ck that the

power supply current is approximately 1.8µA.

8) Turn on the function generator.

9) Observe the input and output signal. The output

signal is an amplified version of the input signal

with an output swing of approximately 400mV

corresponding to a signal gain of two.

Inverting Configuration

In order to evaluate the TS1001 operational amplifier

in the inverting configuration, the following steps are

to be performed:

1) Before connecting the DC power supply to the

demo board, turn on the power supply and set

the DC voltage to 2.5V and then turn it off.

2) Set the function generator output frequency to

500Hz and output level with a V

= 1.35V and a

= 1.15V. This sets the input swing to

200mV

, centered at 1.25V.

3) In order to monitor the input and output signal,

select two channels on the oscilloscope and set

the vertical voltage scale and the vertical position

on each channel to 100mV/DIV and -1.2 5V,

respectively. Set the horizontal time scale to

500µs/DIV.

4) Connect the positive terminal of the DC power

supply to TP4 and the ground terminal to TP5.

For all other connections, please refer to Table 1.

5) Connect the signal output of the function

generator to TP3 and the ground terminal to TP9.

6) To monitor the input, connect the signal terminal

of one of the oscilloscope probes to TP3 and the

ground terminal to TP9. To monitor the output,

use the second probe to connect the signal

terminal to TP2 and the ground terminal to TP9.

7) Turn on the power supply and check th at the

power supply current is approximately 1.7µA.

8) Turn on the function generator.

9) Observe the input and output signal. The output

signal is an inverted version of the input signal

and the swing should be 200mV
