General Description
The KM4100 (single) and KM4101 (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 KM4100 offers superior dynamic performance
with a 260MHz small signal bandwidth and 150V/µs
slew rate. The combination of low power, high
output current drive, and rail-to-rail performance
make the KM4100 well suited for battery-powered
communication/computing systems.
The combination of low cost and high performance
make the KM4100 suitable for high volume applications
in both consumer and industrial applications such as
wireless phones, scanners, and color copiers.
