General Description

The KM4100 (single) and KM4101 (single with disable) are low cost, voltage feedback amplifiers. These amplifiers 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 KM4100 offers superior dynamic performance with a 260MHz small signal bandwidth and 150V/µs slew rate. The combination of low power, high output current drive, and rail-to-rail performance make the KM4100 well suited for battery-powered communication/computing systems.

The combination of low cost and high performance make the KM4100 suitable for high volume applications in both consumer and industrial applications such as wireless phones, scanners, and color copiers.
