FDA802P-VYY

Overview

The FDA802P-VYY is a dual-bridge Class-D digital input automotive power amplifier manufactured by STMicroelectronics. It operates within a supply voltage range of 4.5V to 25V and features two stereo channels. The device is housed in a 64-LQFP-EP package with dimensions of 10x10mm. It supports an operating temperature range from -40°C to 105°C (TA) and holds AEC-Q100 qualification for automotive reliability.

Feature Summary

• Digital input interface for direct connection to audio sources
• Automotive-grade reliability with AEC-Q100 qualification
• Surface-mount installation in a compact LQFP-64 package

Applications

• Car radio applications
• Automotive audio systems
• Power amplification in vehicle infotainment units

Procurement Notes

Verify the specific suffix 'VYY' against official STMicroelectronics documentation, as distributor listings often reference similar variants like 'VYT'. Confirm that the 4.5V-25V supply range aligns with your system design, as other FDA802 family members support up to 50V. Ensure the 64-LQFP-EP footprint matches your PCB layout requirements before finalizing procurement.

Selection Notes

Select this component when a lower voltage operation range (up to 25V) is sufficient for the application, distinguishing it from higher-voltage FDA802 variants. The digital input capability simplifies integration with modern digital audio processors. Verify that the 80W per channel output at 4 ohms meets the acoustic requirements of the target speaker configuration.

Part Context

This part belongs to the FDA802 family of automotive power amplifiers from STMicroelectronics. While other variants in the series, such as the FDA802AB or FDA802S, support boosted supplies up to 50V and offer different power outputs, the FDA802P-VYY is specified for standard battery voltages. It shares the core Class-D architecture but differs in electrical ratings and packaging options.

Replacement Considerations

Direct substitutes include HFDA802-VYY and FDA802S-VYT, though these may have different voltage ranges or diagnostic features. Verify pin compatibility and thermal performance when replacing with other FDA802 family members.
