WM8956CGEFL/V

Overview

The WM8956CGEFL/V is a low-power, high-quality stereo DAC designed for portable multimedia applications. It integrates stereo Class D speaker drivers capable of delivering 1W per channel into 8Ω loads with a 5V supply, alongside headphone and line outputs. The device features 24-bit sigma-delta DACs with digital interpolation filters and supports flexible input configurations for up to three stereo sources and microphone interfaces. Operating with analogue supplies down to 2.7V and digital supplies down to 1.71V, it utilizes a 32-lead QFN (5x5x0.9mm) package suitable for hand-held systems.

Feature Summary

• Stereo Class D Speaker Drivers: Delivers 1W per channel into 8Ω loads at 5V supply with low leakage and pop/click suppression.
• High-Fidelity Audio Performance: Features 24-bit sigma-delta DACs with 99dB SNR (A-weighted) and -87dB THD at 48kHz/3.3V.
• Flexible Input Configuration: Supports up to three stereo sources and complete microphone interfaces without external amplifiers.
• Integrated Clocking: Master clock can be input directly or generated internally via an onboard PLL supporting common clocking schemes.

Applications

• Portable media players
• Games consoles
• Multimedia phones

Procurement Notes

Verify the ordering suffix 'V' indicates tape and reel packaging with a quantity of 3500 units. Confirm the component is Pb-free and meets MSL3 moisture sensitivity standards. Ensure the supplier provides documentation confirming the -40°C to +85°C operating temperature range and the specific 32-lead QFN package dimensions.

Selection Notes

Select this component when designing portable audio systems requiring integrated speaker and headphone driving capabilities. Ensure the application supports the required supply voltage ranges: DCVDD/DBVDD from 1.71V to 3.6V, AVDD from 2.7V to 3.6V, and SPKVDD from 2.7V to 5.5V. Verify that the PCB layout accommodates the 5x5mm QFN package and connects the ground paddle to analogue ground.

Part Context

The WM8956CGEFL/V belongs to the WM8956 series produced by Wolfson Microelectronics plc, now part of Cirrus Logic. It is specifically the version packaged in a 32-lead QFN (5x5x0.9mm) form factor with tape and reel delivery. This variant is distinct from the '/RV' suffix which also denotes tape and reel but may have different handling or storage specifications according to the manufacturer's ordering information.
