UTC571 COMPANDER DESCRIPTION LI NEAR I NTEGRATED CI RCUI T 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 fullwave 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. FEATURES • Complete compressor and expandor in one IChip •Temperature compensated •Greater than 110dB dynamic range • Operates down to 6VDC • System levels adjustable with external components • Distortion may be trimmed out • Voltage-controll [ ... ]
