This operational amplifier uses the ST silicon gate CMOS process giving it an excellent consumption-speed ratio. This Pin Connections (top view) amplifier is ideally suited for low consumption applications. The power supply is externally programmable with 1 8 a resistor connected between pins 8 and 4. It 2 - 7 allows to choose the best consumption-speed 3 + 6 ratio and supply current can be minimized according to the required speed. This device is 4 5 specified for the following ISET current values: 1.5µA, 25µA, 130µA. 1 - Offset Null 1 2 - Inverting Input 1 This CMOS amplifier offers very high input 3 - Non-inverting Input 1 - 4 - V impedance and extremely low input currents. The CC 5 - Offset Null 2 major advantage versus JFET devices is the very 6 - Output 7 - V + low input currents drift with temperature see CC 8 - I Set Figure 8, Figure 19, Figure 30.
