Current Regulation/Management Procurement Notes

Verify the specific suffix 'IDR' corresponds to the SOIC-8 tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the ordering part number matches the required accuracy grade and thermal performance specifications for the target application environment.

Current Regulation/Management Selection Notes

Select this component when wide common-mode voltage coverage up to 80 V is required alongside high-side or low-side monitoring capabilities. Consider the 900 uA supply current consumption relative to system power budgets. Validate that the SOIC-8 package meets the thermal dissipation requirements for the intended operating temperature range of -40°C to +125°C.
