TS274BI Datasheet | STMicroelectronics

DESCRIPTION The TS274 series are low cost, low power quad 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 : q ICC= 10µA/amp. : TS27L4 (very low power) q ICC= 150µA/amp. : TS27M4 (low power) q ICC= 1m A/amp. : TS274 (high speed) These CMOS amplifiers offer very high input impedance and extremely low input currents. The major advantage versus JFET devices is the very low input currents drift with temperature (see figure 2).

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.
