DESCRIPTION
These devices are low cost, low power 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 consumpt ions are av ailable a llowing
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 am plifiers 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).
