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 CMOS
process allowing an excellent consumption-speed
ratio. These series are ideally suited for low con-
sumption applications.
Three power consumptions are available allowing
to have always the best consumption-speed ratio :
q
I
CC
= 10µA/amp. :
TS27L4 (very low power)
q
I
CC
= 150µA/amp. :
TS27M4 (low power)
q
I
CC
= 1mA/amp. :
TS274
(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).

All voltage values, except differential voltage, are with respect to network ground terminal.
Differential voltages are at the non-inverting input terminal with respect to the inverting input terminal.
The magnitude of the input and the output voltages must never exceed the magnitude of the positive supply voltage.
