Versatile dual gain control compander
  AS571 Versatile dual gain control compander 

 AS571 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 linearized temperature-compensated variable gain cell, and an operational amplifier.
AS571 is well suited for use in VCA blocks, noise reduction systems, compandors/expanders ,etc.
