SA571DG Datasheet

Audio Amplifiers


The SA571DG 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 SA571DG is well suited for use in cellular radio and radio communications systems, modems, telephone, and satellite broadcast/receive audio systems. SA571DG 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• Pb−Free Packages are Available* SA571DG Applications • Cellular Radio• High Level Limiter• Low Level Expandor − Noise Gate• Dynamic Filters• CD Player
