• Automotive audio systems utilizing start-stop low voltage specifications
• Integrated solutions requiring high output power under boosted voltage conditions

Procurement Notes

Verify the specific ordering suffix 'VYT' corresponds to the tape and reel packing format as defined in the device summary table. Confirm that the component meets AEC-Q100 (rev. G) qualification requirements for your automotive application. Ensure design compatibility with the LQFP64 package dimensions and thermal management needs associated with the exposed pad configuration.

Selection Notes

Select this component for designs requiring a dual-bridge Class-D amplifier with integrated digital-to-analog conversion. It is suitable for applications needing high output power across varying supply voltages, from standard 14 V batteries up to 50 V boosted supplies. Consider its diagnostic features and EMI control capabilities if system reliability and electromagnetic compatibility are critical constraints.

Part Context

The FDA802 belongs to a family of dual bridge Class-D amplifiers designed using advanced BCD technology. It is specifically intended for car radio applications where high efficiency and low distortion are required. The device combines powerful MOSFET outputs with integrated feedback loops containing output L-C low-pass filters to ensure frequency response linearity independent of external component quality.

Replacement Considerations

The FDA802-VYY is a pin-compatible alternative offering the same functionality but packaged in trays instead of tape and reel. Verify that the change in packaging format aligns with your assembly line equipment and handling requirements before substituting.
