• Consumer electronics with limited board space

Procurement Notes

Verify the specific suffix 'WG' against the official Nuvoton datasheet to confirm pinout and thermal specifications. Ensure the supplier provides documentation matching the 563Kb / 16P reference found in public records. Confirm the manufacturer is Nuvoton Technology Corporation and not an unclassified entity listing similar part numbers.

Selection Notes

Select this component when a mono Class-D solution without output filtering is required. Compare performance metrics such as THD+N and PSRR against other mono amplifiers if noise immunity is critical. Verify that the MSOP-8 package fits the target PCB layout constraints and thermal requirements for the intended power output level.

Part Context

This amplifier belongs to Nuvoton's audio product line, which includes various codecs and amplifiers. It shares functional similarities with other mono Class-D amplifiers in the market but is distinguished by its specific power rating and filter-free implementation. The part is designed for modern consumer electronics requiring compact audio solutions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided data. Cross-reference with other 2.9W mono Class-D amplifiers only after verifying electrical compatibility and pin assignments through official engineering samples or detailed datasheets.
