DESCRIPTION
The TS272 series are low cost, low power dual
operational amplifiers designed to operate with
single or dual supplies. These operational amplifi-
ers use the SGS-THOMSON silicon gate LIN MOS
process giving them 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 =10 m A/amp. : TS27L2 (very low power)
I CC = 150 m A/amp. : TS27M2 (low power)
I CC = 1mA/amp. :

These CMOS amplifiers offer very high input im-
pedance and extremely low input currents. The
major advantage versus JFET devices is the very
low input currents drift with temperature
(see figure 2).

Notes : 1. All voltage values, except differential 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.
