DESCRIPTION

The power supply is externally programmable with a resistor connected between 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 8, Figure 19, Figure 30.
