MAX406AESA+T

The MAX406AESA+T is a single supply, single 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 entire supply range which represents 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, output is capable of sourcing 1.8mA when powered by 9V battery. The MAX406A is a single op-amp with two modes of operation such as compensated mode and decompensated mode. Floating BW (pin 8) or connecting it to V- internally compensates amplifier. This device is used in intrinsically safe systems, electrometer amplifiers, photodiode pre-amps and pH meters, battery powered and medical instruments.
