DESCRIPTION
The NE570/571 is a versatile low cost dual gain control circuit in
which either channel may be used as a dynamic range compressor
or expandor. Each channel has a full-wave rectifier to detect the
average value of the signal, a linerarized temperature-compensated
variable gain cell, and an operational amplifier.
The NE570/571 is well suited for use in cellular radio and radio
communications systems, modems, telephone, and satellite
broadcast/receive audio systems.
