16-Pin Plastic Small Outline Large (SOL) -40 to +85°C SA571D SOT162-1
16-Pin Plastic Dual In-Line Package (DIP) -40 to +85°C SA571N SOT38-4
FEATURES
• Complete compressor and expandor in one IChip
• Temperature compensated
• Greater than 110dB dynamic range
• Operates down to 6VDC
• System levels adjustable with external components
• Distortion may be trimmed out
• Dynamic noise reduction systems
• Voltage-controlled amplifier
DESCRIPTION
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.
