MIC7211/7221
IttyBitty® Rail-to-Rail Input Comparator
General Description
The MIC7211 and MIC7221 are micropower comparators
featuring rail-to-rail input performance in Micrelâs IttyBitty®
SOT-23-5 package. The MIC7211/21 is ideal for systems
where small size is a critical consideration.
The MIC7211/21 is optimized for single supply operation from
2.2V to 10V power supplies.
The MIC7211 features a conventional push-pull output while
the MIC7221 has an open-drain output for mixed-voltage
applications with an external pull-up resistor.
The MIC7211/21 benefits small battery-operated portable
electronic devices where small size and the ability to place
the comparator close to the signal source are primary design
concerns.
