WM8776SEFT/V
Overview
The WM8776SEFT/V is a high-performance 24-bit audio CODEC from Cirrus Logic, featuring a stereo ADC and a stereo DAC with an integrated 5-channel input multiplexer. Designed for high-fidelity audio systems, it supports sampling rates up to 192kHz for the DAC and 96kHz for the ADC, making it ideal for high-resolution digital recording and playback applications. The device operates on a flexible 2.7V to 5.5V analog supply and includes an SPI/I2S interface for control and data streaming.
Why Choose This Part
The integrated 5-channel input multiplexer significantly reduces the need for external switching circuitry in multi-source audio designs. Its support for 192kHz DAC sampling ensures compatibility with high-definition audio standards, while the 24-bit Sigma-Delta architecture maintains high signal-to-noise ratios.
Applications
Key Specifications
Getting Started
Designers should interface the WM8776SEFT/V via the SPI control port for register configuration and the I2S port for digital audio data. Evaluation requires careful PCB layout of the 48-TQFP package to isolate analog and digital ground planes, ensuring the 48mA analog current draw does not introduce noise. Reference the WM8776 evaluation board documentation for optimal decoupling capacitor placement near the 2.7V-5.5V supply pins.
