Audio Amplifiers Procurement Notes

Verify the specific ordering suffix (XUMA1) against the manufacturer's current datasheet to confirm packaging details and reel specifications. Confirm component availability status as distribution listings may indicate end-of-life or discontinuation states. Ensure the procurement source provides valid RoHS compliance documentation matching the official material content sheet.

Audio Amplifiers Selection Notes

Select this component for applications requiring high power efficiency without external output filters. The integrated I2S receiver simplifies system architecture by eliminating external DACs. Consider the thermal resistance characteristics when designing PCB layouts for heatsink-free operation. Verify that the target application supply voltage falls within the specified +4V to +26V range for optimal performance.
