DESCRIPTION

The WM8501 is a high performance stereo DAC with an

integrated 1.7Vrms line driver. It is designed for audio

applications that require a high voltage output along with

enhanced load drive capability.

The WM8501 supports data input word lengths from 16 to

24-bits and sampling rates up to 192kHz. The WM8501

consists of a serial interface port, digital interpolation filters,

multi-bit sigma delta modulators and stereo DAC in a 14-

lead SOIC package.

The hardware control interface is used for the selection of

audio data interface format, enable and de-emphasis. The

Operating on separate analog and digital supplies the

WM8501 offers very lower power consumption from the

digital section, whilst supporting enhanced load drive from

the analogue output.
