FDA802PB-VYT

Overview

The FDA802PB-VYT is a Class-D digital input automotive power amplifier manufactured by STMicroelectronics. It features a 64-lead LQFP package with an exposed pad, measuring 10x10 mm. The device supports flexible channel configurations, operating as either a mono or stereo amplifier. It is designed for high-voltage automotive environments with a supply voltage range of 5.5 V to 50 V. The component meets AEC-Q100 qualification standards and operates within a temperature range of -40°C to +125°C.

Feature Summary

• Digital input interface for direct connection to audio sources
• Flexible mono or stereo channel configuration
• Integrated I2C diagnostics for system monitoring
• Automotive-grade reliability under harsh conditions

Applications

• Automotive center console speaker systems
• Vehicle door panel audio amplification
• High-fidelity car audio subwoofer drivers
• Multi-zone automotive sound distribution networks

Procurement Notes

Verify the specific suffix 'PB' against the official STMicroelectronics datasheet to confirm pinout and functional compatibility. Ensure the design accounts for the LQFP-64 thermal requirements and moisture sensitivity levels during assembly. Confirm that the digital input signal levels match the amplifier's specifications before integration into the final product architecture.

Selection Notes

Select this component when a robust, digitally controlled audio solution is required for automotive interiors. It is suitable for designs needing both stereo separation and mono bridging capabilities within a single IC. Consider the thermal performance of the exposed pad package and the availability of I2C diagnostic features for advanced vehicle health monitoring systems.

Part Context

This part belongs to the FDA802 family of automotive power amplifiers from STMicroelectronics. The family includes variants such as FDA802S and HFDA802, which offer different power outputs and feature sets. The FDA802PB variant specifically targets applications requiring versatile channel modes while maintaining high efficiency and low distortion in compact automotive enclosures.

Replacement Considerations

Check for FDA802S-VYT or HFDA802-VYT if higher power output or different diagnostic features are needed. Verify pin-to-pin compatibility with existing PCB layouts before substituting. Consult the latest PCN documents for any manufacturing changes that might affect form, fit, or function.
