General Description
The KM4111 (single) and KM4121 (single with disable)
are ultra-low power, low cost, voltage feedback
amplifiers. These amplifiers use only 208µA of supply
current and 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 KM4111 offers high bipolar performance at a
low CMOS price. The KM4111 offers superior dynamic
performance with a 35MHz small signal bandwidth
and 27V/µs slew rate. The combination of lowpower,
high bandwidth, and rail-to-rail performance make
the KM4111 well suited for battery-powered commu-
nication/computing systems.
