The NE570 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 NE570 is well suited for use in cellular radio .
OUTPUT_1 THD_TRIM_1
• Complete compressor and expandor in one IC
• Temperature compensated
• Greater than 110 dB dynamic range
• Operates down to 6 VDC
• System levels adjustable with external components
• Distortion may be trimmed out
