Procurement Notes

Verify the specific datasheet revision and ordering suffix to ensure compatibility with your system requirements. Confirm that the 20-QFN (5x5) package footprint matches your PCB layout constraints. Check for any regional distribution restrictions or availability updates directly from authorized Broadcom partners before finalizing procurement plans.

Selection Notes

Select this component when interfacing with second-order sigma-delta modulators requiring multi-channel digital filtering. Ensure the operating voltage range of 3 V to 5.5 V aligns with your system power rails. Consider the thermal performance of the QFN package if high ambient temperatures are expected in the application environment.

Part Context
