SA571
Compandor
The SA571 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 SA571 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
• Pb−Free Packages are Available*
Applications
• Cellular Radio
• High Level Limiter
• Low Level Expandor − Noise Gate
• Dynamic Filters
• CD Player
