• INA3221 datasheet · updated 2026-09-16

  Texas Instruments SBOS576C, revised September 2025. The ±163.84 mV shunt span, the 40 µV and 8 mV register steps, the eight conversion times, the four addresses in Table 7-1, the critical and warning alert behaviour in section 7.3.2, and the 10 V / 9 V power-valid defaults all come from here. Across the board's 50 mΩ shunts that ±163.84 mV is the 3.28 A printed on its back.
