General Description

The KM4200 is a dual, low cost, voltage feedback amplifier. This amplifier 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 KM4100 (single) and KM4101 (single with disable) are also available.
