Unity gain level programmable low power compandor
Product specification
NE/SA577
DESCRIPTION
The NE/SA577 is a unity gain level
programmable compandor designed for low
power applications. The NE577 is internally
configured as an expandor and a compressor
to minimize external component count.
The NE577 is available in a 14-pin plastic
DIP and SO packages.
