The 100 µV input offset voltage keeps measurement error low even with small shunt voltages. The 20 V maximum supply span means the part can sit directly on a nominal 12 V battery line (which can spike to 18 V during cold crank) without a pre-regulator. The 1.5 mA supply current is moderate — fine for a powered module, but not the lowest draw for a battery-backed always-on sense node.","metaTitle":"INA281A5QDBVRQ1 Current Sense Amplifier, AEC-Q100, SOT-23-5","metaDescription":"TI INA281A5QDBVRQ1 automotive current sense amplifier, AEC-Q100 qualified, 2.7V–20V supply, 1.3 MHz GBW, SOT-23-5.
