This operational amplifier uses the SGS-THOMSON silicon gate CMOS process giving 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 impedance and extremely low input currents. The major advantage versus JFET devices is the very low input currents drift with temperature (see figure 3). PIN CONNECTIONS (top view) 1 2 3 4 + 8 7 6 5 1 - Offset Null 1 2 ...
