General Description
The KM4210 is a dual, low power, low cost, voltage
feedback amplifier. The KM4210 uses only 505碌A
of supply current per amplifer, and is designed to
operate on +2.7V, +5V, or 鹵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/碌s 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.
