General Description

The MIC7111 is a micropower operational amplifier featuring

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 elec-

tronic devices where small size and the ability to place the

amplifier close to the signal source are primary design

concerns.
