WM8772SEDS/RV

Overview

The WM8772SEDS/RV is a multi-channel audio codec manufactured by Cirrus Logic, designed for high-fidelity audio processing in consumer electronics. It integrates a stereo 24-bit sigma-delta ADC and three stereo 24-bit sigma-delta DACs, supporting sampling rates from 8kHz to 192kHz. The device features independent digital volume and mute control for each DAC channel. It accepts digital audio inputs with word lengths from 16 to 32 bits and supports I2S, left-justified, right-justified, and DSP formats via a serial interface. Controlled through a 3-wire serial port, it includes power management and de-emphasis capabilities.

Feature Summary

• Integrates stereo ADC and triple stereo DAC channels for surround sound applications
• Supports variable sampling rates between ADC and DAC sections in specific package variants
• Provides independent digital volume and mute controls per output channel
• Compatible with multiple standard digital audio interface protocols

Applications

• DVD players and home theater systems
• Surround sound processing for automotive audio
• High-fidelity home hi-fi equipment
• Audio visual receivers and media players

Procurement Notes

Verify the exact suffix configuration against current manufacturer documentation, as packaging and lead-free status may vary. Confirm availability through authorized distributors, noting that end-of-life notifications may affect long-term supply. Ensure compatibility with existing board layouts and serial control logic before procurement.

Selection Notes

Select this component when multi-channel output with individual channel control is required. Verify if the specific package variant supports independent sample rates for ADC and DAC, as this feature depends on the pin count. Ensure the system design accommodates the required serial interface protocol and voltage levels for both analog and digital domains.
