DESCRIPTION
The M65817AFP is a S-Master technique processor for digital amplifier enable to convert from multi liner-PCM digital input signal
to high precise switching-pulse digital output without analog signal.The M65817AFP has built-in 24bit sampling rate converter and
digital-gain-controller.
The M65817AFP enables to realize high precise ( X`tal oscillation precision) full digital amplifier systems combining with power
driver IC.
