Programmable analog compandor

DESCRIPTION
The NE572 is a dual-channel,
high-performance gain control circuit in which
either channel may be used for dynamic
range compression or expansion. Each
channel has a full-wave rectifier to detect the
average value of input signal, a linearized,
temperature-compensated variable gain cell
(
G) and a dynamic time constant buffer. The
buffer permits independent control of
dynamic attack and recovery time with
minimum external components and improved
low frequency gain control ripple distortion
over previous compandors.
The NE572 is intended for noise reduction in
high-performance audio systems. It can also
be used in a wide range of communication
systems and video recording applications.
