DESCRIPTION
The WM8759 is a high performance stereo DAC with an
integrated headphone driver. It is designed for audio
applications such as portable DVD, MP3 players or
consumer equipment with line output and headphone output
connections.
The WM8759 supports data input word lengths from 16 to
24-bits and sampling rates up to 192kHz. The WM8759
consists of a serial interface port, digital interpolation filters,
multi-bit sigma delta modulators and stereo DAC in a 14-pin
SOIC package.
The hardware control interface is used for the selection of
audio data interface format, enable and de-emphasis. The
WM8759 supports I
S, right Justified or DSP interfaces.
Operating on split analog digital supplies the WM8759
allows very lower power consumption from the digital
section, whilst supporting large output powers from the
analog headphone driver.
