MIC7211

Micrel, Inc. MIC7211/7221 MIC7211/7221 IttyBitty® Rail-to-Rail Input Comparator General Description 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. 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. Features Small footprint SOT-23-5 package Guaranteed performance at 2.2V, 2.7V, 5V, and 10V 7µA typical supply current at 5V <5µs response time at 5V Push-pull output (MIC7211) Open-drain output (MIC7221) ...
