Active production — what it means for the BOM line
The INA381A3IDGST: The part is ROHS3 compliant, which clears the regulatory gate for EU and similar markets without an exemption review.
±1% accuracy and the measurement budget
The ±1% accuracy figure is the total unadjusted error across the rated input range — it sets the floor for the current-measurement uncertainty in the system. For a 10 A full-scale shunt, that is ±100 mA before any external resistor tolerance or temperature drift is added. High/low-side sensing means the amplifier can be placed between the supply and the load (high-side) or between the load and ground (low-side), giving layout flexibility depending on whether the load is grounded or floating.
Temperature grade and package fit
Supplied in a 10-MSOP (3.00 mm width) body, also listed as 10-VSSOP — the two package designations refer to the same footprint. The 0.50 mm pitch demands a standard fine-pitch PCB process; the small outline suits dense mixed-signal boards where board area is at a premium.
