Its input common-mode range extends from -0.1 V to 26 V, which means it can sit on either the high side or the low side of the supply rail and still measure the drop across the shunt resistor accurately. The ±1.5% accuracy ceiling holds across that entire range, so the gain error budget does not shift as the rail voltage varies. ## Temperature grade and deployment context The 14 kHz bandwidth is sized for DC and low-frequency current loops — motor phase currents, solenoid drive monitoring, or battery charge/discharge profiles — not for high-speed switching edges.","metaTitle":"Texas Instruments INA199B3RSWT Current Sense, ±1.5%, 10-UQFN","metaDescription":"Texas Instruments INA199B3RSWT Zero-Drift current-sense amplifier. ±1.5% accuracy, -0.1V to 26V input range, -40°C to 125°C.
