The rail-to-rail output stage swings within millivolts of both supply rails, preserving dynamic range in low-voltage systems. ## Bandwidth and slew rate — matching the signal to the measurement The gain-bandwidth product is 35 kHz and the -3 dB bandwidth is 20 kHz, with a slew rate of 0.25 V/µs. That bandwidth suits DC and low-frequency AC current monitoring — think motor winding current, battery charge/discharge profiles, or power-supply output monitoring. It is not meant for fast-switching waveforms like those from a high-frequency buck converter; for that, a current-sense amplifier with a 350 kHz bandwidth (such as the INA254A1IPWAR in the same Zero-Drift family) would be the better fit, though at the cost of higher supply current. ## Temperature range and package — industrial and automotive readiness The 10-UFQFN package (1.8 mm x 1.4 mm body) is a compact, leadless package suited for space-constrained PCBs. The supplier device package is 10-UQFN (1.8x1.4). Surface-mount assembly is standard; the small footprint demands careful solder-paste stencil design to avoid bridging.","metaTitle":"Texas Instruments INA190A3IRSWT Current-Sense Amplifier","metaDescription":"Zero-Drift current-sense amplifier in 10-UQFN. 2 µV offset, 40 µA supply, 1.7 V to 5.5 V range. -40°C to 125°C.
