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

• Internally compensated

• 2MHz bandwidth

• 6V/

µs typical slew rate

• Short circuit protected

Applications

• Analog building blocks

• Summing amplifier

• Gain block
