WM8581
Multichannel CODEC with S/PDIF Transceiver
DESCRIPTION
FEATURES
The WM8581 is a multi-channel audio CODEC with S/PDIF
transceiver. The WM8581 is ideal for DVD and surround
• Multi-channel CODEC with 4 Stereo DACs and 1 Stereo
ADC
sound processing applications for home hi-fi, automotive
and other audiovisual equipment.
• Integrated S/PDIF / IEC-60958-3 transceiver
• Audio Performance
Integrated into the device is a stereo 24-bit multi-bit sigma
− 103dB SNR (‘A’ weighted @ 48kHz) DAC
delta ADC with support for digital audio output word lengths
from 16-bit to 32-bit, and sampling rates from 8kHz to
192kHz.
− -90dB THD (48kHz) DAC
− 100dB SNR (‘A’ weighted @ 48kHz) ADC
− -87dB THD (48kHz) ADC
Also included are four stereo 24-bit multi-bit sigma delta
DACs, each with a dedicated oversampling digital
interpolation filter. Digital audio input word lengths from 16-
bits to 32-bits and sampling rates from 8kHz to 192kHz are
supported. Each DAC channel has independent digital
volume and mute control.
Two independent audio data interfaces support I2S, Left
Justified, Right Justified and DSP digital audio formats.
Each audio interface can operate in either Master Mode or
Slave Mode.
• DAC Sampling Frequency: 8kHz – 192kHz
• ADC Sampling Frequency: 8kHz – 192kHz
• Independent ADC and DAC Sample Rates
• 2 and 3-Wire Serial Control Interface with readback, or
Hardware Control Interface
• GPO pins allow visibility of user selected status flags
• Programmable Audio Data Interface Modes
− I2S, Left, Right Justified or DSP
− 16/20/24/32 bit Word Lengths
The S/PDIF transceiver is IEC-60958-3 compatible
supports frame rates from 32k/s to 96k/s. It has
multiplexed inputs and one output. Status and

external use.
Device control and setup is via a 2-wire or 3-wire (SPI
compatible) serial interface. The serial interface provides
access to all features including channel selection, volume
controls, mutes, de-emphasis, S/PDIF control/status, and
power management facilities. Alternatively, the device has a
Hardware Control Mode where device features can be
enabled/disabled using selected pins.
APPLICATIONS
• Digital TV
• DVD Players and Receivers
• Surround Sound AV Processors and Hi-Fi systems
• Automotive Audio
The device is available in a 48-lead TQFP package.
