General Description
The KM4112 is an ultra-low power, low cost, voltage
feedback amplifier. The KM4112 uses only 70
μ
A of
supply current and is 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 KM4112 offers high bipolar performance at a low
CMOS price. The KM4112 offers superior dynamic
performance with a 7.3MHz small signal bandwidth
and 9V/
μ
s slew rate. The combination of low power,
high bandwidth, and rail-to-rail performance make
the KM4112 well suited for battery-powered commu-
nication/computing systems.
