The MAX406BESA+ is a single 1.2μA max, operational amplifier (op-amp) in 8 pin NSOIC package. This low voltage, micropower, precision op-amp is designed for battery-operated systems. The single supply device features a supply current of less than 1.2μA per amplifier that is relatively constant over the entire supply range which represents a 15 to 20 times improvement over industry standard micropower op-amp. A unique output stage enables this op-amp to operate at ultra-low supply current while maintaining linearity under loaded conditions. In addition, the output is capable of sourcing 1.8mA when powered by a 9V battery. This device is used in intrinsically safe systems, electrometer amplifiers, photodiode pre-amps and pH meters.
