DESCRIPTION
The TS274 series are low cost, low power quad
operational amplifiers designed to operate with
single or dual supplies.These operational amplifiers use the SGS-THOMSON silicon gate CMOS
processallowing an excellentconsumption-speed
ratio. These series are ideally suited for low consumption applications.
Three power consumptions are available allowing
to have always the best consumption-speedratio:
● I
=10µA/amp.: TS27L4 (very low power)
CC
● I
= 150µA/amp. : TS27M4 (low power)
CC
● I
= 1mA/amp. : TS274 (high speed)
CC
These CMOS amplifiers offer very high input impedance and extremely low input currents.
The major advantage versus JFET devices is the
very low input currentsdrift withtemperature
(see figure2).
