DESCRIPTION
SA8507 is a automatic gain control system that is used for dynamic range compression and expansion. According to the companding the signal, this can reduce the noise components. SA8507 includes compressor, expander, pre-amp, filter amp, limiter and mute/bypath logic.
FEATURES
- Wide supply voltage: 2.4V ~ 7V * Easy gain control * Mute/bypath logic * Data in/out pin SOP-20 DIP-20
