WM8776SEFT/RV

Overview

The WM8776SEFT/RV 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 96 kHz for the ADC and 192 kHz for the DAC. The device supports digital word lengths from 16 to 32 bits and offers an SNR of 108 dB for the DAC and 102 dB for the ADC at 48 kHz. It operates on 2.7 V to 5.5 V analogue supplies and 2.7 V to 3.6 V digital supplies. The component is housed in a 48-pin TQFP package.

Feature Summary

• Five stereo channel input selector with programmable gain control
• Independent sample rate operation 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 the specific suffix RV indicates tape and reel packaging versus the slash V variant which denotes drybagged units. Confirm moisture sensitivity level MSL2 requirements are met during storage. Check for end-of-life status or discontinuance notifications prior to finalizing procurement plans.

Selection Notes

Select this component when multi-channel analogue input selection is required within a stereo CODEC architecture. Ensure the design accommodates separate master clocks for independent ADC and DAC sampling rates. Verify that the 48-pin TQFP footprint fits the PCB layout constraints.

Part Context

This part belongs to the WM8776 series produced by Wolfson Microelectronics plc, now Cirrus Logic. It is designed as a high-performance solution for audio visual equipment requiring flexible input routing and high-fidelity conversion capabilities.
