Datasheet Summary
NE570 pandor
The NE570 is a versatile low cost dual gain control circuit in which either channel may be used as a dynamic range pressor or expandor. Each channel has a full- wave rectifier to detect the average value of the signal, a linerarized temperature- pensated variable gain cell, and an operational amplifier. The NE570 is well suited for use in cellular radio and radio munications systems, modems, telephone, and satellite broadcast/receive audio systems.
