WM8912CGEFL/V

Overview

The WM8912CGEFL/V is a high-performance ultra-low power stereo DAC optimized for portable audio applications. It features Class-W ground-referenced headphone amplifiers with an integrated dual-mode charge pump, eliminating the need for external coupling capacitors. The device supports standard sample rates from 8kHz to 96kHz and operates from a single 1.8V switched supply, with a digital core running at 1.0V. Key electrical specifications include a typical DAC SNR of 96dB and THD of -86dB. Quiescent power consumption for DAC-to-headphone playback is 3.8mW.

Feature Summary

Class-W ground-referenced headphone driver delivering 28mW per channel into 30Ω and 32mW per channel into 15Ω at <1% THD
Integrated ReTune Mobile 5-band parametric equalizer with fully programmable coefficients
Dynamic range controller with anti-clip and quick release features for impulsive noise handling
Integrated control write sequencer for minimized pops and clicks during startup and shutdown

Applications

Portable multimedia players
Multimedia handsets
Handheld gaming devices

Procurement Notes

Verify the ordering suffix 'V' corresponds to the tray package variant (32-lead QFN) rather than the '/RV' tape and reel version. Confirm the temperature range is -40°C to +85°C and that the component is lead-free. Ensure the source document matches the Wolfson Microelectronics production data revision 4.1 dated February 2013.

Selection Notes

Select this component when ground-referenced outputs are required to reduce BOM size by removing coupling capacitors. The integrated charge pump architecture is suitable for optimizing efficiency in battery-powered devices. Verify that the application requires a dedicated stereo DAC with headphone drivers rather than a full codec with ADC capabilities.

Part Context

The WM8912 is part of the Wolfson Microelectronics (now Cirrus Logic) portfolio of ultra-low power audio components. It is functionally related to the WM8904 and WM8978 series but focuses specifically on DAC and headphone amplification without integrated analog-to-digital conversion or microphone inputs.
