M65817FP
STREAM PROCESSOR
DESCRIPTION
The M65817FP is a Processor f or Digital Amplif ier enable to conv ert ing extreme accurately v arious Linear PCM Digital Input Signal into Switching Pulse Signal, without Analog Stage. Built-in 24bit Sampling rate conv erter & Digital Gain Control. According to adding to Power Driv er , it realizes Full Digital Amplif ier Sy s t em on Extremely Accurate (Cry s t al Oscillating Accuracy ).
FEATURES
