SELECTIONSDESCRIPTION

The TS272 devices are low cost, dual operationalamplifiers designed to operate with single or dualsupplies. These operational amplifiers use the STsilicon gate CMOS process allowing an excellentconsumption-speed ratio. These series are ideallysuited for low consumption applications.

Three power consumptions are available allowingto have always the best consumption-speed ratio:

DSO8(Plastic Micropackage)NDIP8(Plastic Package)PTSSOP8(Thin Shrink Small Outline Package)uICC = 10µA/amp.: TS27L2 (very low power)uICC = 150µA/amp.: TS27M2 (low power)uICC = 1mA/amp.: TS272 (standard)

These CMOS amplifiers offer very high input im-pedance and extremely low input currents. Themajor advantage versus JFET devices is the verylow input currents drift with temperature (see fig-ure 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.
