NE570
Description
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.
Key Features
- 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
