Micrel, Inc. MIC7211/7221 MIC7211/7221
IttyBitty® Rail-to-Rail Input Comparator General Description Features The MIC7211 and MIC7221 are micropower comparators
featuring rail-to-rail input performance in Micrel’s 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. Small footprint SOT-23-5 package
Guaranteed performance at 2.2V, 2.7V, 5V, and 10V
7µA typical supply current at 5V
100mA typical sink or source Applications 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. • • • • • • Battery-powered products
