DESCRIPTION

These devices are low cost, low power quad 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:

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).
