Audio Codec 2ADC /2 DAC 24-Bit 28-Pin SSOP

The WM8569 is a stereo audio codec ideal for DVD, PVR, LCD-TV and automotive applications. Independent ADC and DAC clocking permits separate record and playback sampling rates.A stereo 24-bit multi-bit Delta Sigma DAC with oversampling and 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.A stereo 24-bit multi-bit Delta Sigma ADC is used. Digital audio output word lengths from 16-24 bits and sampling rates from 32kHz to 96kHz are supported. The DAC and ADC support independent sampling rates. The audio data interface supports I²S, left justified, right justified and DSP digital audio formats.The device is controlled via a three-wire serial interface. The interface provides access to all features including volume controls, mutes, de-emphasis and power management facilities. A hardware control interface allows access to a limited feature set. The WM8569 is available in a 28-lead SSOP.
