The MAX9041AESA+ is a micropower, single supply, comparator + precision reference IC in 8 pin NSOIC package. It has a single comparator and reference consuming only 40µA of supply current. Low voltage operation and low supply current make the device ideal for battery operated systems. The comparators feature rail to rail inputs and outputs with a common-mode input voltage range that extends 250mV beyond the supply rails. Input bias current is typically 1.0pA and input offset voltage is typically 0.5mV. Internal hysteresis ensures clean output switching, even with slow-moving input signals. The output stage features a unique design that limits supply current surges while switching, virtually eliminating supply glitches typical of many other comparators. This design also minimizes overall power consumption under dynamic conditions. The comparator outputs have rail to-rail, push-pull output stages except the MAX9038 has an open-drain output that sinks and sources up to 8mA.
