General Description
The KM4200 is a dual, low cost, voltage feedback
amplifier. This amplifier is designed to operate on
+2.7V, +5V, or 鹵2.5V supplies. The input voltage
range extends 300mV below the negative rail and
1.2V below the positive rail. The KM4100 (single) and
KM4101 (single with disable) are also available.
The KM4200 offers superior dynamic performance
with a 260MHz small signal bandwidth and 145V/碌s
slew rate. The combination of low power, high out-
put current drive, and rail-to-rail performance make
the KM4200 well suited for battery-powered com-
munication/computing systems.
The combination of low cost and high performance
make the KM4200 suitable for high volume applica-
tions in both consumer and industrial applications
such as wireless phones, scanners, and color copiers.
