DESCRIPTION

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

amplifier.

The UTC571N is well suited for use in cellular radio and radio

communication systems, modems, telephone, and satellite

broadcast/receive audio systems.
