The KM4212 uses only 70µA 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 communication/computing systems. The KM4112 single amplifier is also available. 70µA supply current 7.3MHz bandwidth Fully specified at +2.7V and +5V supplies Output voltage range: 0.04V to 4.96V; Vs = +5 Input voltage range: -0.3V to +3.8V; Vs = +5 9V/µs slew rate ±4mA linear output current ±9mA short circuit output current 29nV/√Hz input voltage noise Competes with low power CMOS amps Small package options (SOIC-8 and MSOP-8) Applications I I I I I Portable/battery-powered applications A/D buffer Active filters Signal conditioning Portable test instruments Non-Inverting Freq.
