WM8728SEDS/V

Overview

The WM8728SEDS/V is a stereo digital-to-analog converter (DAC) manufactured by Cirrus Logic. It features a 24-bit resolution and supports sampling frequencies up to 192 kHz. The device operates on a single power supply ranging from 3 V to 5.5 V for both analog and digital sections. It utilizes an I2S serial interface for data input. The component is housed in a 20-lead SSOP package with a width of 5.30 mm. This audio DAC is designed for high-fidelity sound reproduction applications requiring precise digital conversion.

Feature Summary

• Stereo digital-to-analog conversion capability
• High-resolution 24-bit audio processing
• Support for high sample rates up to 192 kHz
• I2S compatible serial data interface

Applications

• High-fidelity audio systems
• Professional audio equipment
• Home theater receivers
• Digital audio workstations

Procurement Notes

Verify the exact suffix and package dimensions against the official datasheet before integration. Confirm power supply requirements match the 3V to 5.5V range. Check for end-of-life status or obsolescence notices from the manufacturer. Ensure thermal management meets the specified operating temperature range. Validate pin compatibility with the target PCB footprint.

Selection Notes

Choose this component when stereo output with 24-bit precision is required. Consider the 192 kHz support for high-resolution audio sources. Verify that the I2S interface aligns with the system's digital processor. Assess the 20-SSOP package constraints for board space. Evaluate power consumption within the specified voltage limits.

Part Context

This part belongs to the Cirrus Logic WM8728 series of audio codecs. It is specifically configured as a DAC-only device in the SEDS/V variant. The series targets consumer and professional audio markets. Competing products often offer similar bit depths but may differ in interface protocols. The SSOP package provides a compact solution for dense circuit designs.

Replacement Considerations

Check for direct pin-compatible substitutes in the same family. Verify if newer generations maintain the 24-bit/192kHz specification. Ensure interface compatibility remains unchanged. Review updated datasheets for any parameter shifts. Consult manufacturer documentation for approved cross-references.
