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 elec-
tronic devices where small size and the ability to place the
amplifier close to the signal source are primary design
concerns.
