WM8776SEFT/V

Overview

The WM8776SEFT/V is a stereo audio CODEC featuring a five-channel input multiplexer, manufactured by Cirrus Logic. It integrates a 24-bit sigma-delta ADC and DAC with sampling rates up to 96kHz and 192kHz respectively. The device supports digital word lengths from 16 to 32 bits and operates on 2.7V to 5.5V analogue supplies and 2.7V to 3.6V digital supplies. Key performance metrics include 108dB SNR for the DAC and 102dB SNR for the ADC at 48kHz. It utilizes a 48-pin TQFP package and offers independent sample rate operation for ADC and DAC paths.

Feature Summary

• Five stereo channel input selector with programmable gain control
• Independent sample rate support for ADC and DAC sections
• Integrated headphone and line outputs with volume controls
• Supports I2S, left justified, right justified, and DSP data formats

Applications

• Surround sound AV processors
• Home hi-fi systems
• DVD-RW equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix indicates tape and reel packaging if required for automated assembly. Check for moisture sensitivity level compliance and storage conditions prior to soldering. Ensure the ordering information matches the exact voltage and temperature range requirements of the target application.

Selection Notes

Select this component when a multi-channel input selection capability is required within a stereo audio path. Verify that the operating supply voltages align with the system's analogue and digital rails. Consider the available package type and pin configuration for PCB layout constraints. Evaluate the need for independent ADC and DAC clock domains against system synchronization requirements.
