General Description

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 volt-

age 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 pull-up current

source that can be used instead of an external load in some

applications.
