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.
