Procurement Notes

Verify the specific suffix 'V0Y' against official STMicroelectronics documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the intended digital audio interface configuration. Confirm AEC-Q100 qualification status for the specific variant before finalizing procurement plans.

Selection Notes

Select this component for applications requiring a single-channel solution with integrated digital-to-analog conversion. It is suitable for designs needing wide voltage operation from 3.3 V to 18 V. Consider its low quiescent current and configurable amplitude limiter for power-sensitive automotive environments.

Part Context

This part belongs to the FDA803 series of automotive Class-D power amplifiers. It shares functional similarities with the FDA803D and FDA903Q models but is distinguished by its specific packaging and interface configuration. The series is designed for modern infotainment and safety-critical automotive audio applications.

Replacement Considerations

The FDA803D serves as a related single-channel alternative within the same family. Verify pinout and software compatibility when substituting between FDA803Q and FDA803D variants due to potential differences in package or specific diagnostic feature sets.
