GENERAL DESCRIPTION
The Winbond W6631CS is a low cost stereo audio DAC
chip incorporating 8X digital interpolatioin filters, 64X
multi-level
oversampling
analog low-pass filter and output amplifiers. The
operation voltage for this chip can be from 3.0 volt to
5.25 volt. Moreover, the 16 Bit linear input data for
DAC consists of two formats, normal format and I
2
S
format. In addition, the device provides DAC mute,
digital 44.1KHz de-emphasis and format conversions
can be set up by external pins.
