This operational amplifier uses the ST silicon gate CMOS process giving it an excellent consumptionspeed ratio. This amplifier is eally suited for low consumption applications. The power supply is externally programmable with a resistor connected between pins 8 and. It allows to choose the best consumptionspeed ratio and supply current can be minimized according to the required speed. This device is specified for the following I SET current values :.µa, µa, µa. 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 ).
