NCY9100

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 6.0 VDC System Levels Adjustable with External Components Distortion may be Trimmed Out Dynamic Noise Reduction Systems Voltage Controlled Amplifier This is a Pb−Free Device Applications Cellular Radio High Level Limiter Low Level Expandor − Noise Gate Dynamic Filters CD Player http://onsemi.com 16 1 SOIC−16 WB D SUFFIX CASE 751G A WL YY WW G MARKING DIAGRAMS 16 NCY9100 AWLYYWWG 1 = Assembly Location = Wafer Lot = Year = Work Week = Pb−Free Package PIN CONNECTIONS RECT CAP 1 1 RECT IN 1 2 DG CELL IN 1 3 GND 4 INV.
