Includes internal RF noise suppression and differential architecture
Features pop and click suppression mechanisms
Supports direct battery connection due to low leakage characteristics

Applications

Mobile phones
Portable navigation devices
Portable media players
Laptop computers
Electronic dictionaries

Procurement Notes

Verify the specific suffix 'R' indicates the reel packaging configuration as documented in the ordering information. Confirm that the component is sourced from authorized distributors to ensure authenticity. Check for any end-of-life notifications or production data revisions relevant to this specific part number before finalizing procurement plans.

Selection Notes

Select this component when a flexible mono speaker driver is required for portable electronics. Consider the Class D mode for higher efficiency or Class AB for specific audio fidelity requirements. Ensure the system design accommodates the 3x3mm QFN package dimensions and provides adequate thermal dissipation paths for the specified power output levels.

Part Context

The WM9001 is part of the Wolfson Microelectronics portfolio, now under Cirrus Logic. It is designed to work standalone or with CODECs like the WM8991. The GEFL/R designation specifies the QFN package type and reel packaging format. This component targets applications requiring high-quality audio amplification in compact form factors.
