WM8718SEDS/V

Overview

The WM8718SEDS/V is a high-performance differential stereo digital-to-analog converter (DAC) manufactured by Cirrus Logic. It supports PCM data input word lengths from 16 to 32 bits and sampling rates up to 192 kHz. The device integrates a serial interface port, digital interpolation filters, multi-bit sigma-delta modulators, and differential stereo DAC outputs within a 20-lead SSOP package. Key electrical specifications include a signal-to-noise ratio of 111 dB (A-weighted at 48 kHz), total harmonic distortion of -100 dB, and operation with supply voltages ranging from 3.0 V to 5.5 V.

Feature Summary

• 24-bit resolution with support for 16/20/24/32-bit word lengths
• Sampling frequency range from 8 kHz to 192 kHz
• 111 dB SNR and -100 dB THD performance
• 3-wire serial control interface supporting I2S, Left/Right Justified, and DSP modes

Applications

• DVD players
• Home theatre systems
• Digital TV sets

Procurement Notes

Verify the specific suffix 'V' against official documentation to confirm lead-free status and tape-and-reel packaging configuration. Confirm current lifecycle status as the component may be discontinued or subject to product change notifications. Ensure compatibility with existing board layouts designed for the 20-lead SSOP form factor.

Selection Notes

Select this component for applications requiring high-fidelity audio reconstruction with differential output stages. Verify that the host processor supports the required 3-wire serial interface protocols. Ensure power supply rails are stable within the 3.0 V to 5.5 V range to maintain specified audio performance metrics.

Part Context

This part belongs to the WM8718 family of audio DACs. The SEDS/R variant typically denotes a reel-packaged version, while the SEDS/V designation indicates specific packaging or environmental compliance attributes. It serves as a dedicated digital-to-analog conversion solution for consumer audio electronics.

Replacement Considerations

Direct pin-compatible replacements within the same family include the WM8718SEDS/R. Other Cirrus Logic stereo DACs may require schematic and firmware modifications due to differences in interface protocols or pin configurations.
