MIC6211
IttyBittyTM Operational Amplifier
Preliminary Information
General Description
The MIC6211 IttyBittyTM op amp is a general-purpose, high-
performance, single- or split-supply, operational amplifier in
a space-saving, surface-mount package.
The MIC6211 operates from 4V to 32V, single or differential
(split) supply. The input common-mode range includes ground.
The device features a 2.5MHz unity gain bandwidth, 6V/
s
slew rate, and is internally unity-gain compensated.
Inputs are protected against reverse polarity (input voltage
less than V) and ESD (electrostatic discharge). Output is
current limited for both sourcing and sinking. Output short
circuits of unlimited duration are allowed, provided the power
dissipation specification is not exceeded.
The MIC6211 is available in the tiny, 5-lead SOT-23-5 sur-
face-mount package.
