UTC571N

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.
