Current Sensors Procurement Notes

This component is marked as Not Recommended for New Designs (NRND). Procurement should verify availability constraints and potential minimum order quantity limitations associated with end-of-life status. Ensure the specific suffix matches required sensitivity and packaging preferences before ordering.

Current Sensors Selection Notes

Select this part for bidirectional AC/DC current measurement requiring high bandwidth up to 90kHz. Verify that the 8-SOIC package dimensions fit the PCB layout. Confirm if the fixed factory sensitivity of 270mV/mT meets system requirements or if programmability is necessary for calibration adjustments.

Current Sensors Part Context
