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 136
μ
A 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/
μ
s 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.
