DESCRIPTION
The TS272 devices are low cost, dual 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
= 10µA/amp.: TS27L2 (very low power)
❑ I
CC
= 150µA/amp.: TS27M2 (low power)
❑ I
CC
= 1mA/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).
