DESCRIPTION

The TS274 series are low cost, low power quad

operational amplifiers designed to operate with

single or dual supplies. These operational amplifi-

ers use the SGS-THOMSON silicon gate CMOS

process allowing an excellent consumption-speed

ratio. These series are ideally suited for low con-

sumption applications.

Three power consumptions are available allowing

to have always the best consumption-speed ratio :

q

µA/amp. :

TS27L4

(very low power)

q

µA/amp. : TS27M4 (low power)

q

TS274

(high speed)

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 figure 2).
