DESCRIPTION
The TS271 is a low cost, low power single opera-
tional amplifier designed to operate with single or
dual supplies. This operational amplifier uses the
SGS-THOMSON silicon gate CMOS process giv-
ing it an excellent consumption-speed ratio. This
amplifier is ideally suited for low consumption
applications.
The power supply is externally programmable with
a resistor connectedbetween pins 8 and 4. It allows
to choose the best consumption-speed ratio and
supply current can be minimized according to the
required speed. This device is specified for the
following ISET current values : 1.5µA, 25µA, 130µA.
This CMOS amplifier offers very high input imped-
ance and extremely low input currents. The major
advantage versus JFET devices is the very low
input currents drift with temperature (see figure 3).
