DESCRIPTION
D
SO8
(Plastic Micropackage)
The TS272 devices are low cost, dual operational
amplifiers designed to operate with single or dual
supplies. These operational amplifiers use the ST
silicon gate CMOS process allowing 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:
P
TSSOP8
(Thin Shrink Small Outline Package)
❑ ICC = 10µA/amp.: TS27L2 (very low power)
❑ ICC = 150µA/amp.: TS27M2 (low power)
PIN CONNECTIONS (top view)
❑ ICC = 1mA/amp.: TS272 (standard)
These CMOS amplifiers offer very high input impedance and extremely low input currents. The
major advantage versus JFET devices is the very
low input currents drift with temperature (see figure 2).

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