KM4112

70µA, Low Cost, +2.7V & +5V, 7.3MHz Rail-to-Rail Amplifier

Features

General Description

The KM4112 is an ultra-low power, low cost, voltage

feedback aꢀplifier. The KM4112 uses only 70µA of

supply current and is designed to operate on +2.7V,

+5V, or 2.5V supplies. The input voltage range

extends 300ꢀV below the negative rail and 1.2V

below the positive rail.

Coꢀpetes with low power CMOS aꢀps

The KM4112 offers high bipolar perforꢀance at a low

CMOS price. The KM4112 offers superior dynaꢀic

perforꢀance with a 7.3MHz sꢀall signal bandwidth

and 9V/µs slew rate. The coꢀbination of low power,

high bandwidth, and rail-to-rail perforꢀance ꢀake

the KM4112 well suited for battery-powered coꢀꢀu-

nication/coꢀputing systeꢀs.
