UTC571N Datasheet (UTC)

UTC571N, COMPANDOR

The UTC571N 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
