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
WM8501 supports I
2
S, right Justified or DSP interfaces.
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.
