UTC571N

LINEAR INTEGRATED CIRCUIT

COMPANDER

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,

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.

FEATURES

* Complete compressor and expandor in one Chip

* 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

* Voltage-controlled amplifier
