Procurement Notes

Verify the component status before integration, as the FDA802S-VYT is listed as Not Recommended for New Designs (NRND). Confirm availability through authorized distributors, noting that current stock levels may be limited or unavailable. Ensure compliance with RoHS directives and check for any recent Product Change Notifications (PCN) affecting manufacturing or packaging details prior to procurement.

Selection Notes

Select this component for designs requiring a dual-channel Class-D amplifier with digital input and diagnostic features. It is suitable for applications needing operation under boosted supply voltages up to 50 V. Consider the NRND status when planning long-term production cycles. Verify compatibility with the target PCB footprint, specifically the LQFP-64 package, and ensure the design supports the required I2C interface for configuration and diagnostics.
