TS27M2C,I,M PRECISION LOW POWER

CMOS DUAL OPERATIONAL AMPLIFIERS

LOW POWER CONSUMPTION : 150µA/op OUTPUT VOLTAGE CAN SWING TO GROUND EXCELLENT PHASE MARGIN ON CAPACITIVE LOADS STABLE AND LOW OFFSET VOLTAGE

DIP8 (Plastic Package)

THREE INPUT OFFSET VOLTAGE SELECTIONS

DESCRIPTION

These devices are low cost, low power dual oper-

ational amplifiers designed to operate with single

(Plastic Micropackage)

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

TSSOP8

to have always the best consumption-speed ratio:

(Thin Shrink Small Outline Package)

ICC = 10µA/amp.: TS27L2 (very low power)

PIN CONNECTIONS (top view)

ICC = 150µA/amp.: TS27M2 (low power) ICC = 1m A/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).
