The NE570 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 is well suited for use in cellular radio and radio
communications systems, modems, telephone, and satellite
broadcast/receive audio systems.
