DESCRIPTION

The TS272 series are low cost, low power dual operational amplifiers designed to operate with single or dual supplies. These operational amplifiers use the SGS-THOMSON silicon gate CMOS process allowing an excellent consumption-speed ratio. These series are ideally suited for low consumption applications.

Three power consumptions are available allowing to have always the best consumption-speed ratio :

● I

CC

= 10µA/amp. : TS27L2 (very low power)

● I

CC

= 150µA/amp. : TS27M2 (low power)

● I

CC

= 1mA/amp. : TS272 (high speed)

These CMOS amplif iers offer very high input impedance and extremely low input currents. The major advantage versus JFE T devices is the very low input currents drift with temperature (see figure 2).

Notes : 1. All voltage values, except diff erential voltage, are with respect to network ground terminal.

2. Differential voltages are at the non-inverting input terminal with respect to the inverting input terminal.

3. The magnitude of the input and the output voltages must never exceed the magnitude of the positive supply voltage.
