General Description
The KM4211 is a dual ultra-low power, low cost,
voltage feedback amplifier. The KM4211 uses only
208µA of supply current per amplifier and is designed
to operate from 2.5V to 5.5V or ±1.25V to ±2.75V
supplies. The input voltage range extends 300mV below
the negative rail and 1.2V below the positive rail.
The KM4211 offers high bipolar performance at a
low CMOS price. The KM4211 offers superior
dynamic performance with a 35MHz small signal
bandwidth and 27V/µs slew rate. The combination
of low power, high bandwidth, and rail-to-rail
performance make the KM4211 well suited for
battery-powered communication/computing systems.
The KM4112 (single) and KM4121 (single with disable)
are also available.
