TS274C,I,M PRECISION ERY OW POWER CMOS QUAD OPERATIONA AMPIFIER ERY OW POWER CONSUMPTION : µa/op OUTPUT OTAGE CAN SWING TO GROUND EXCEENT PHASE MARGIN ON CAPACITIE OADS STABE AND OW OFFSET OTAGE THREE INPUT OFFSET OTAGE SEECTIONS DESCRIPTION These devices are low cost, low power 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 ratio. These series are ideally suited for low consumption applications. Three power consumptions are available allowing to have always the best consumption-speed ratio: I CC = µa/amp.: TS274 (very low power) I CC = 0µA/amp.: TS27M4 (low power) I CC = ma/amp.: TS274 (standard) 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).
