Description
The KM7101 is an ultra-low cost, low power, voltage feed-
back amplifier that is pin compatible to the LMC7101. If a
standard pinout is required, use the KM4170. The KM7101
uses only 136µA of supply current and offers no crossover
distortion. The input common mode voltage range exceeds
the negative and positive rails.
The KM7101 offers high bipolar performance at a low
CMOS price. The KM7101 offers superior dynamic perfor-
mance 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 KM7101 well suited for
battery-powered communication/computing systems.
