General Description
The KM4270 is a dual ultra-low cost, low power,
voltage feedback amplifier. At 5V, the KM4270 uses
only 160
µA of supply current per amplifier and is
designed to operate from a supply range of 2.5V to
5.5V. The input voltage range exceeds the negative
and positive rails. The KM4170 (single) and KM4470
(quad) are also available.
The KM4270 offers high bipolar performance at a low
CMOS price. The KM4270 offers superior dynamic
performance with a 4.9MHz small signal bandwidth
and 5.3V/
µs slew rate. The combination of low power,
high bandwidth, and rail-to-rail performance make
the KM4270 well suited for battery-powered com-
munication/computing systems.
