Procurement Notes

Verify the specific gain configuration required for your design, as the part number suffix may indicate different gain settings. Confirm that the SOT-25-5 package footprint matches your PCB layout. Ensure the supply voltage constraints (2.7 V to 5.5 V) align with your system's power rails. Check for any specific automotive qualification requirements beyond standard AEC-Q100 if applicable to your final product certification.

Selection Notes

Select this component when precise current monitoring is needed in automotive or industrial environments. The wide common-mode range allows flexibility in sensing placement relative to ground. Consider the available gain options to match the expected current levels and desired output voltage swing. Verify thermal performance requirements, as accuracy is specified over a wide temperature range.
