The AS571D is Alfa’s version of the NE571 or SA571 in an SOIC package. AS571 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 linearized temperature-compensated variable gain cell, and an operational amplifier. AS571 is well suited for use in VCA blocks, noise reduction systems, compandors/expanders ,etc. Features
Applications
- Complete compressor and expandor
- Temperature compensated
- Channel separation >86 dB
- Greater than 110 dB dynamic range
- Levels adjustable with external components
- Distortion may be trimmed out
Applications
- VCA
- High level limiter
- Low level expandor − noise gate
- Dynamic filters
- Dynamic noise reduction systems
