COMPANDOR
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.

* Temperature compensated
* Greater than 110dB dynamic range
* Operates down to 6VDC
* System levels adjustable with external components
* Distortion may be trimmed out
* Dynamic noise reduction systems
