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

µA, 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).
