These amplifiers use only 208 µA 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/ µs slew rate. The combination of lowpower, high bandwidth, and rail-to-rail performance make the KM4111 well suited for battery-powered commu- nication/computing systems.
