DESCRIPTION

The SA571 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 SA571 is well suited for use in cellular radio and radio

communications systems, modems, telephone, and satellite

broadcast/receive audio systems.
