DESCRIPTION
The TS271 is a low cost, low power single oper-
tional amplifier designed to operate with single or
dual supplies. This operational amplifier uses the
ST silicon gate CMOS process giving it an excel-
lent consumption-speed ratio. This amplifier is ide-
ally suited for low consumption applications.
The power supply is externally programmable with
a resistor connected between pins 8 and 4. It al-
lows 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 in-
put currents drift with temperature (see figure 3).
