The KM4111 (single) and KM4121 (single with disable) are ultra-low power, low cost, voltage feedback amplifiers. These amplifiers use only 208A of supply  current and 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 KM4111 offers high bipolar performance at a low CMOS price. The KM4111 offers superior dynamic performance with a 35MHz small signal bandwidth and 27V/s slew rate. The combination of lowpower, high bandwidth, and rail-to-rail performance make the KM4111 well suited for battery-powered communication/ computing systems.
