General Description

The KM4210 is a dual, low power, low cost, voltage

feedback amplifier. The KM4210 uses only 505

µA

of supply current per amplifer, 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 KM4210 offers high bipolar performance at a

low CMOS price. The KM4210 offers superior

dynamic performance with a 75MHz small signal

bandwidth and 50V/

µs slew rate. The combination

of low power, high bandwidth, and rail-to-rail

performance make the KM4210 well suited for

battery-powered communication/computing systems.

The KM4110 (single) and KM4120 (single with disable)

are also available.
