7V & +5V, 35MHz Rail-to-Rail Amplifiers Features I I I I I I I I I I I I General Description The KM4111 (single) and KM4121 (single with disable) are ultra-low power, low cost, voltage feedback amplifiers.
These amplifiers use only 208µA 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 communication/computing systems.
