NE571 - Compandor
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 am
