Product Description
The NE570 Compandor 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 temperaturecompensated variable gain cell, and an operational amplifier. The NE570 is well suited for use in cellular radio and radio
communications systems, modems, telephone, and satellite broadcast/receive audio systems.
