KM4112 General Description

The KM4112 is an ultra-low power, low cost, voltage feedback amplifier. The KM4112 uses only 70A ofsupply current and is designed to operate on +2.7V, +5V, or ±2.5V supplies. The input voltage range extends 300mV below the negative rail and 1.2V below the positive rail.

The KM4112 offers high bipolar performance at a low CMOS price. The KM4112 offers superior dynamic performance with a 7.3MHz small signal bandwidth and 9V/s slew rate. The combination of low power, high bandwidth, and rail-to-rail performance make the KM4112 well suited for battery-powered communication/ computing systems.
