SA8507
VOICE SIGNAL COMPRESSION AND EXPANSION CIRCUIT WITH AUTO GAIN
CONTORL
DESCRIPTION
SA8507 is a automatic gain control system that is used for dynamic
range compression and expansion. According to the companding the
signal, this can reduce the noise components. SA8507 includes
compressor, expander, pre-amp, filter amp, limiter and mute/bypath
logic.
