General Description

The MIC7111 is a micropower operational amplifier featuring rail-to-rail input and output performance in Micrel’s IttyBitty™ SOT-23-5 package. The MIC7111 is ideal for systems where small size is a critical consideration.

The MIC7111 is designed to operate from 1.8V to 11V power supplies.

The MIC7111 benefits small battery operated portable electronic devices where small size and the ability to place the amplifier close to the signal source are primary design concerns.
