The rail-to-rail output stage keeps the full ADC input range usable at low supply voltages. The 1.7 V minimum supply span lets it run from a single Li-ion cell or a 1.8 V rail, and the 48 µA quiescent current keeps the power budget lean in battery-operated equipment. Surface-mount assembly on a standard SC-70-6 footprint; the Tape & Reel option suits automated pick-and-place for medium-to-high volume builds.","metaTitle":"TI INA190A2IDCKT Zero-Drift Current Sense Amplifier, SC-70-6","metaDescription":"Texas Instruments INA190A2IDCKT Zero-Drift current sense amplifier. 3 µV offset, 37 kHz GBW, 48 µA supply, -40°C to 125°C.

Both share the same pinout and supply range, so a direct replacement is possible if the gain (A2 vs A1) meets the system requirement.
