General Description
The KM4211 is a dual ultra-low power, low cost,
voltage feedback amplifier. The KM4211 uses only
208碌A of supply current per amplifier and is designed
to operate from 2.5V to 5.5V or 鹵1.25V to 鹵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/碌s 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.
