TS27L2C/AC/BC
DESCRIPTION
The TS272 series are low cost, low power dual operational amplifiers designed to operate with single
or dual supplies. These operational amplifiers use
the SGS-THOMSONsilicon gate CMOS process allowing an excellent consumption-speed ratio.
These series are ideally suited for low consumption
applications.
Threepower consumptionsare available allowing to
have always the best consumption-speedratio :
l ICC = 10mA/amp. : TS27L2 (very low power)
l ICC= 150mA/amp. :
TS27M2(low power)
l ICC= 1mA/amp. : TS272
(high speed)
These CMOS amplifiers offer very high input impedance and extremely low input currents. The major
advantageversus JFET devices is the very low input
currents drift with temperature (see figure 2).
