• Integrated high-performance 110 dB D/A conversion
• Supports I2S and TDM digital input interfaces
• AEC-Q100 qualified for automotive reliability

Applications

• Car radio systems
• Automotive audio amplification
• Digital audio processing units

Procurement Notes

Verify the specific suffix 'VYY' against official STMicroelectronics documentation, as datasheets often reference 'VYT'. Confirm current production status, as related FDA802 variants may be marked as Not Recommended for New Designs (NRND). Ensure compatibility with required digital input voltages and packaging specifications before procurement.

Selection Notes

Select this component for designs requiring integrated digital-to-analog conversion and robust automotive-grade reliability. The dual bridge configuration supports flexible speaker arrangements. Verify that the system design accommodates the 64-lead LQFP package dimensions and thermal requirements associated with the exposed pad.

Part Context

This part belongs to the FDA802 family of dual bridge Class-D amplifiers designed specifically for automotive environments. The family leverages BCD technology to combine power and digital functions on a single chip, simplifying system architecture for modern vehicle infotainment and audio distribution networks.

Replacement Considerations

Check for FDA802P-VYT or FDA802S-VYT as potential functional equivalents within the same family. Verify if the suffix change impacts pinout or electrical characteristics. Note that some FDA802 variants are listed as NRND; confirm availability and lifecycle status of substitutes.
