TS274

High performance CMOS quad ooperational amplifiers

Description

The TS274 devices are low cost, quad operational

amplifiers designed to operate with single or dual

supplies. These operational amplifiers use the ST

silicon gate CMOS process allowing an excellent

consumption-speed ration. These series are ideally

suited for low consumption applications.

Three power consumptions are available allowing

to have always the best consumption-speed ratio:

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).
