These devices are low cost, low power dual oper- ational amplifiers designed to operate with single or dual supplies. These operational amplifiers use the ST silicon gate CMOS process allowing an ex- cellent 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: · ICC = 10µA/amp.: TS27L2 (very low power) · ICC = 150µA/amp.: TS27M2 (low power) · ICC = 1mA/amp.: TS272 (standard)
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 fig- ure 2).
