MIC6270
IttyBittyВ® Comparator General Description Features 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.
