n STABLE AND LOW OFFSET VOLTAGE
n THREE INPUT OFFSET VOLTAGE
SELECTIONS
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 consumptions are available allowing
to have always the best consumption-speed ratio:
q ICC = 10?A/amp.: 27L2 (very low power)
q ICC = 150?A/amp.: 27M2 (low power)
q ICC = 1mA/amp.: 272 (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
