Procurement Notes

Verify the complete part number including the suffix 'MNR2G' to ensure correct tape-and-reel packaging configuration. Confirm that the required operating temperature range aligns with your system's thermal design specifications. Ensure compatibility with the 4.75 V to 5.25 V supply voltage domain. Check for any specific ESD handling requirements during assembly. Validate that the 16-QFN footprint matches your PCB layout constraints.

Selection Notes

Select this component when precise digital current measurement is required within a 5 V logic domain. Consider its small 3x3 mm package for dense board layouts. Evaluate its 1.6 mA supply current against system power budgets. Ensure the -40°C to +125°C rating meets environmental demands. Compare performance metrics against alternative monitors if higher precision or different voltage ranges are needed.
