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:
u I_CC = 10µA/amp.: TS27L4 (very low power)
u I_CC = 150µA/amp.: TS27M4 (low power)
u I_CC = 1mA/amp.: TS274 (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).
