WM8759
24-bit 192kHz Stereo DAC with Headphone Buffer
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 I2S, 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.

ABSOLUTE MAXIMUM RATINGS
Absolute Maximum Ratings are stress ratings only. Permanent damage to the device may be caused by continuously operating at
or beyond these limits. Device functional operating limits and guaranteed performance specifications are given under Electrical
Characteristics at the test conditions specified.
ESD Sensitive Device. This device is manufactured on a CMOS process. It is therefore generically susceptible
to damage from excessive static voltages. Proper ESD precautions must be taken during handling and storage
of this device.
Wolfson tests its package types according to IPC/JEDEC J-STD-020B for Moisture Sensitivity to determine acceptable storage
conditions prior to surface mount assembly. These levels are:
MSL1 = unlimited floor life at <30°C / 85% Relative Humidity. Not normally stored in moisture barrier bag.
MSL2 = out of bag storage for 1 year at <30°C / 60% Relative Humidity. Supplied in moisture barrier bag.
MSL3 = out of bag storage for 168 hours at <30°C / 60% Relative Humidity. Supplied in moisture barrier bag.
The Moisture Sensitivity Level for each package type is specified in Ordering Information.
