The ICL7612DCBAZ is a low power CMOS Operational Amplifier for use with high impedance buffers. This device provides the designer with high performance operation at low supply voltages and selectable quiescent currents and is an ideal design tool when ultra low input current and low power dissipation are desired. The basic amplifier will operate at supply voltages ranging from ±1 to ±8V and may be operated from a single Lithium cell. Unique quiescent current programming pin allows setting of standby current to 1mA, 100μA or 10μA, with no external components. This results in power consumption as low as 20μW. The output swing ranges to within a few millivolts of the supply voltages. These features optimize performance in very high source impedance applications. The inputs are internally protected. Outputs are fully protected against short circuits to ground or to either supply.
