MAX409BCSA+

The MAX409BCSA+ is a 1.2µA maximum, single low voltage, micropower precision op-amp in 8 pin NSOIC package. It 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 amps. 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. The common-mode input-voltage range extends from the negative rail to within 1.1V of the positive supply (for the singes, 1.2V for the duals and quads) and the output stage swings rail to rail. The entire family is designed to maintain good DC characteristics over the operating temperature range, minimizing the input referred errors. It is specially designed for battery operated systems.
