The KM4212 uses only 70 µA of supply current and 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 KM4212 offers high bipolar performance at a low CMOS price. The KM4212 offers superior dynamic performance with a 7.3MHz small signal bandwidth and 9V/ µs slew rate. The combination of low power, high bandwidth, and rail-to-rail performance make the KM4212 well suited for battery-powered commu- nication/computing systems. The KM4112 single amplifier is also available. KM4212 Dual, 70 µA, Low Cost, +2.7V & +5V, 7.3MHz Rail-to-Rail Amp www.fairchildsemi.com REV. 1 August 2001 Non-Inverting Freq.
