MIC6251/6252
IttyBitty™ GainBlock™ Amplifiers
Preliminary Information
General Description
The MIC6251 and MIC6252 are IttyBitty™ GainBlock™
amplifiers for use as follows:
MIC6251 ................................ +2, +1, –1 gain amplifier
MIC6252 .................................. +0.5, +1 gain amplifier;
average value amplifier
The MIC6251 and MIC6252 amplifiers operate from 4V to
32V. Both can use single or split supplies. These amplifiers
feature internal, well-matched, gain-setting resistors and an
input common-mode range that includes the negative supply
(ground).
The MIC6251/2 is available in the tiny SOT-23-5 surface
mount package.
Features
• 4V to 32V operation
• Small footprint package
