The zero-drift architecture holds input offset voltage to 2 µV, which means the error from the amplifier itself stays below a few microvolts over temperature — no calibration trim needed in production. Supply current is 40 µA, making it viable for always-on current monitoring in battery-powered gear. ## 35 kHz bandwidth — what it resolves and what it doesn't The -3 dB bandwidth is 35 kHz with a slew rate of 0.25 V/µs. That is enough to capture DC load changes and low-frequency ripple on a power rail — think motor start-up current profiles, battery discharge curves, or steady-state overcurrent detection. It will not resolve fast switching edges from a buck converter at 500 kHz or a short-circuit pulse under a few microseconds. If the application needs sub-microsecond fault detection, a comparator-based current-sense solution is the right call. ## Temperature grade and package — industrial/automotive environment ready The 10-UQFN package (1.8x1.4 mm body) is a fine-pitch, leadless package — expect a 0.5 mm or 0.4 mm pitch. Reflow profile follows standard JEDEC MSL 1/2/3 prep; the tiny pad means the stencil aperture for the thermal pad (if present) needs careful sizing to avoid solder bridging on the perimeter lands. ## Lifecycle and compliance — active, ROHS3, no LTB risk ROHS3 compliant, so no RoHS exemption expiry to track for EU or California markets. The zero-drift series is a current product line; second-source alternatives are limited (see FAQ).","metaTitle":"TI INA190A3IRSWR Current Sense Amplifier, 35 kHz, 10-UQFN","metaDescription":"Zero-drift current sense amp, 2 µV offset, 40 µA supply, 1.7-5.5 V, -40 to 125°C, 10-UQFN.
