General Description

The MIC7111 is a low-power operational amplifier with

rail-to-rail inputs and outputs. The device operates from

a 1.8V to 11V single supply or an ±0.9V to ±5.5V dual

supply. The device consumes a low 15 μA of current

from a 1.8V supply and 25 μA from a 10V supply. The

device features a unity gain bandwidth of 25 kHz and

swings within 1 mV of either the supply rail with a

100 kΩ load. The device is capable of sinking and

sourcing 25 mA of current from a 1.8V supply and up to

200 mA from a 10V supply. The device is available in

the cost effective SOT23-5 package.
