- Tablet computers
Procurement Notes
Verify the specific suffix 'V' against the manufacturer's official datasheet to confirm package type and tape-and-reel configuration. Ensure compatibility with RoHS directives and check for any recent Product Change Notifications that may affect pinout or material composition before finalizing procurement orders.
Selection Notes
Select this component when designing systems requiring integrated stereo codec functionality with built-in headphone amplification. It is suitable for battery-operated devices due to its low voltage operation range. Compare performance metrics such as SNR and power consumption against alternative models like the WM8904 if stricter power constraints exist.
Part Context
This part belongs to the Cirrus Logic WM8912 series of audio codecs. It is functionally related to other members in the family such as the WM8918, which shares similar packaging but may differ in integrated features. The CGEFL/V designation indicates the commercial temperature grade, QFN package, and specific reel variant.
Replacement Considerations
Potential substitutes within the same product line include the WM8918CGEFL/RV. Verify pin compatibility and feature parity, particularly regarding the presence of integrated headphone drivers, before implementing any cross-model replacements.
