WM8736
24-bit, 96kHz 6-Channel DAC with Volume Control
Production Data, January 2001, Rev 2.1
DESCRIPTION
The WM8736 is a high performance 6-channel DAC
designed for audio applications such as DVD, home theatre
systems, and digital TV. The WM8736 supports data input
word lengths from 16 to 24-bits and sampling rates up to
96kHz. The WM8736 consists of a serial interface port,
digital interpolation filters, multi-bit sigma delta modulators
and 6 DACs in a small 28-pin SSOP package. The
WM8736 also includes a digitally controllable mute and
attenuator function on each channel.
The WM8736 supports a variety of connection schemes for
audio DAC control. The SPI-compatible serial port provides
access to a wide range of features including on-chip mute,
attenuation and phase reversal. A hardware controllable
interface is also available.
The WM8736 is an ideal device to interface to AC-3,
DTS, and MPEG audio decoders for surround sound
applications.

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.
