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.","metaTitle":"Texas Instruments INA381A3IDGST Current Sense, ±1% Accuracy","metaDescription":"Active-production current-sense amplifier from Texas Instruments, ±1% accuracy, high/low-side sensing, 0–26 V input, -40°C to 125°C.
