MIC7221 - Rail-to-Rail Input Comparator

Download the MIC7221 datasheet PDF. This datasheet also covers the MIC7211 variant, as both devices belong to the same rail-to-rail input comparator family and are provided as variant models within a single manufacturer datasheet.

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.

Key Features

  • a conventional push-pull output while the MIC7221 has an open-drain output for mixed-voltage.

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.
