General Description
The KM7101 is an ultra-low cost, low power, voltage
feedback 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 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 per-
formance make the KM7101 well suited for battery-
powered communication/computing systems.
