The MIC6270 is a precision voltage comparator with an offset voltage specification of 5mV maximum. The MIC6270 is designed to operate from a single 2V to 36V power supply. Operation from split power supplies is also possible. Its low supply current drain is independent of the magnitude of the supply voltage.This comparator also features an input common-mode voltage range that includes ground. Inputs are protected against reverse polarity (input voltage less than V–) and ESD.The MIC6270 has an open-collector output that directly interfaces with TTL, CMOS, and other types of logic. Several MIC6270 outputs can be connected together for wired-OR logic. The output also features an internal pullup current source that can be used instead of an external load in some applications.
