www.fairchildsemi.com KM4110/KM4120 0.5mA, Low Cost, +2.7V & +5V, 75MHz Rail-to-Rail Amplifiers Features s s s s s s s s s s s General Description The KM4110 (single) and KM4120 (single with disable) are low cost, voltage feedback amplifiers. These amplifiers 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 KM4110 offers superior dynamic performance with a 75MHz small signal bandwidth and 50V/µs slew rate. The combination of low power, high output current drive, and rail-to-rail performance make the KM4110 well suited for battery-powered communication/ computing systems. The combination of low cost and high performance make the KM4110 suitable for high volume applications in both consumer and industrial applications such as wireless phones, scanners, and color copiers. s 505µA supply current 75MHz bandwidth Power down to Is = 33µA (KM4120) Fully specified at +2.7V and +5V supplies Output voltage range: 0.07V to 4.86V; Vs = +5 Input voltage range: -0.3V to +3.8V; Vs = +5 50V/µs slew rate ±15mA linear output current ±30mA output short circuit current 12nV/√Hz input voltage noise Directly replaces AD8031 in single supply applications Small package options (SOT23-5 and SOT23-6) Applications s s s s s Portable/battery-powered applications A/D buffer Active filters Signal conditioning Portable test instruments Non-Inverting Freq.
