Audio Amplifiers Procurement Notes

Verify the specific suffix DEWV against the manufacturer's official ordering guide to confirm the 30-bump WLP package variant. Ensure compatibility with the required I2C address and PCM interface settings for your system design. Cross-reference the datasheet revision date to confirm the accuracy of electrical characteristics before finalizing procurement specifications.

Audio Amplifiers Selection Notes

Select this component when a single-channel solution with integrated power management is required. The built-in boost converter eliminates external inductors for basic operation, though inductor selection remains necessary for optimal performance. Consider the 30-bump WLP package constraints regarding PCB real estate and thermal dissipation requirements for dense mobile designs.
