INTEGRATED CIRCUITS NE570 Compandor Product data Supersedes data of 1990 Jun 07 2003 Apr 03 Philips Semiconductors Philips Semiconductors Product data Compandor NE570 GENERAL DESCRIPTION The NE570 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 NE570 is well suited for use in cellular radio and radio communications systems, modems, telephone, and satellite broadcast/receive audio systems.
