A stereo 24-bit multi-bit sigma delta DAC with oversampling digital interpolation filters provides the output signal. Digital audio input word lengths from 16-24 bits and sampling rates from 8kHz to 192kHz are supported. Stereo analog-to-digital conversion is provided by a 24-bit multi-bit sigma delta ADC, again supporting output word lengths from 16-24 bits and sampling rates from 32kHz to 96kHz. The audio data interface supports I2S, left justified, right justified and DSP digital audio formats. PRODUCT BENEFITS TARGET APPLICATIONS All the benefits of an independent audio DAC and ADC in one device. Simplifies designs and lowers costs for home entertainment systems DVD Recorder Personal Video Recorder Independent ADC and DAC rates and formats on the same chip PC Sound Card Hardware control for easy design implementation Automotive Audio High performance audio at a competitive price LCD-TV Low pin count and PCB space reduces manufacturing costs WFN181_WM8569(flyer)_AW.qx 21/12/05 14:42 Page 2 Multi-Channel CODEC withwith S/PDIF Transceiver 24 -bit, 192 k HAudio z Stereo CODEC Volume Control WM8569 PRODUCT FEATURES PRODUCT DETAILS 103dB SNR (‘A’ weighted @ 48kHz) DAC HARDWARE OR SOFTWARE CONTROL DAC Sampling Frequency: 8kHz – 192kHz The device can be controlled via a 3-wire serial or hardware interface.
