    NCY9100 Compandor The NCY9100 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 NCY9100 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 110 dB Dynamic Range • Operates Down to 6.
