The KM4110 (single) and KM4120 (single with disable) are low cost, voltage feedback amplifiers. These amplifiers KM4120 are 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 KM4120 offers superior dynamic performance with a 75MHz small signal bandwidth and 50V/s slew rate. The combination of low power, high output current drive, and rail-to-rail performance make the KM4110 well suited for battery-powered communication/ computing systems.

The combination of low cost and high performance  make the KM4120 suitable for high volume applications in both consumer and industrial applications such as wireless phones, scanners, and color copiers.
