DESCRIPTION
The TS272 series are low cost, low power dual op-
erational amplifiers designed to operate with single
or dual supplies. These operational amplifiers use
the SGS-THOMSON silicon gate CMOS process al-
lowing an excellent consumption-speed ratio.
These series are ideally suited for low consumption
applications.
Three power consumptionsare available allowing to
have always the best consumption-speed ratio :
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 imped-
ance and extremely low input currents. The major
advantageversus JFET devices is the very low input
currents drift with temperature (see figure 2).
