The UTC571 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 UTC571 is well suited for use in cellular radio and
radio communications systems, modems, telephone, and
satellite broadcast/receive audio systems.
