WM8772SEDS/V

Overview

The WM8772SEDS/V is a multi-channel audio codec manufactured by Cirrus Logic, designed for high-fidelity audio processing in home hi-fi, automotive, and audiovisual equipment. It integrates a stereo 24-bit sigma-delta ADC and three stereo 24-bit sigma-delta DACs. The device supports digital audio input word lengths from 16 to 32 bits with sampling rates up to 192kHz for the DAC section. The ADC section supports sampling rates from 32kHz to 96kHz. It features independent digital volume and mute control for each DAC channel and utilizes a 3-wire serial interface for configuration.

Feature Summary

• Integrates stereo 24-bit sigma-delta ADC and three stereo 24-bit sigma-delta DACs with oversampling digital interpolation filters.
• Supports multiple digital audio interface formats including I2S, left justified, right justified, and DSP modes.
• Provides independent digital volume and mute control for each DAC channel via a 3-wire serial interface.

Applications

• DVD and surround sound processing applications
• Home hi-fi systems
• Automotive audio equipment
• Audiovisual equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific package variant (SSOP-28) matches design requirements. Review latest datasheet revisions for any pinout or electrical characteristic updates before finalizing procurement orders.

Selection Notes

Select this component when multi-channel output with individual volume control is required alongside stereo input. Ensure system clocking supports the specified ADC and DAC sampling rate ranges. Verify that the 3-wire serial interface compatibility exists within the host controller design. Consider thermal dissipation capabilities within the SSOP-28 package for the intended operating environment.

Part Context

This part belongs to the WM8772 series of multi-channel codecs from Cirrus Logic. It is distinct from single-channel or simpler stereo-only converters by offering six DAC channels and one stereo ADC pair. The SEDS/V suffix indicates the specific SSOP-28 package variant with lead-free plating and tape-and-reel packaging options available from certain sources.

Replacement Considerations

Direct pin-to-pin replacements are not explicitly confirmed in public documentation. Evaluate other Cirrus Logic multi-channel codecs such as the WM8770 or WM8771 for functional similarity, but verify pinout compatibility and register mapping differences carefully before substitution.
