Procurement Notes

Verify the specific suffix LAE2 against official RoHM documentation to confirm exact ordering details and revision status. Ensure compatibility with the TSSOP-B8J footprint during PCB layout. Confirm that the single-channel configuration meets system requirements before procurement. Cross-reference datasheet electrical characteristics with actual operating conditions to guarantee performance within specified limits.

Selection Notes

Select this component when precise current sensing is required in industrial environments with varying common mode voltages. The fixed 20V/V gain simplifies design by eliminating external resistor adjustments. Consider the wide input voltage range if the application involves 12V or 24V power systems. The low operating current makes it suitable for energy-efficient designs where standby power consumption must be minimized.
