WM8850GEFL/V

Overview

The WM8850GEFL/V is a multi-channel High Definition Audio CODEC designed for high-performance PC audio systems. It features full compatibility with the Intel HDA specification revision 1.0 and includes three stereo DACs for six channels of audio output, alongside two stereo ADCs for input digitization. The device supports DAC sampling frequencies from 8kHz to 192kHz and ADC sampling frequencies from 8kHz to 96kHz. Key performance metrics include a DAC SNR of 108 dB (A-weighted) and an ADC SNR of 105 dB (A-weighted). Power supplies operate at 1.62V–1.98V for the digital core, 2.97V–3.63V for the digital buffer, and 4.5V–5.25V for analogue and charge pump sections.

Feature Summary

Procurement Notes

Verify the component against the official Cirrus Logic datasheet Rev 4.0 to confirm pinout alignment and electrical specifications. Ensure that the ordering suffix matches the required package variant. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before integration into production designs.

Selection Notes

Select this component for applications requiring strict compliance with Intel HDA Revision 1.0 standards. Evaluate power supply requirements carefully, as the device necessitates distinct voltage rails for digital core, digital buffer, and analogue sections. Consider the 48-pin QFN package dimensions when designing PCB footprints and thermal management strategies for dense system layouts.
