Procurement Notes

Verify the obsolete lifecycle status before procurement planning. Confirm package dimensions match the 35-WLCSP specification. Ensure design compatibility with existing digital audio interfaces. Check for available replacement components due to end-of-life status.

Selection Notes

Select this component for applications requiring integrated boost conversion and speaker monitoring. Consider the small WLCSP footprint for space-constrained designs. Evaluate the need for Class-G efficiency improvements over standard Class-D solutions. Verify support for required digital audio protocols.

Part Context

This part belongs to Nuvoton's NAU83xx series of audio amplifiers. It is designed for portable computing devices where power efficiency and audio quality are critical. The series typically integrates boost converters to maximize speaker output power within limited supply voltage constraints.

Replacement Considerations

Check for NAU8331 variants or similar Class-D boost amplifiers from other manufacturers. Verify pinout compatibility if substituting. Review updated datasheets for any functional changes in successor models.
