DESCRIPTION
The TS274 series are low cost, low power quad
operational amplifiers designed to operate with
single or dual supplies. These operational amplifi-
ers use the SGS-THOMSON silicon gate LIN MOS
process giving them 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 :

(high speed)
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 figure 2).
