TS272 - STMicroelectronics

TS272 HIGH SPEED CMOS DUAL OPERATIONAL AMPLIFIERS

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 ha.

Features

0µA/amp. : TS27M2 (low power) q ICC= 1mA/amp. : TS272 (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).
