It measures current by amplifying the voltage drop across a shunt resistor, outputting a rail-to-rail signal proportional to the load current. With a gain-bandwidth product of 45 kHz and an input offset voltage of 3 µV, it resolves small differential signals accurately without external trimming. The part operates from 1.7 V to 5.5 V supply and draws 48 µA quiescent current, making it suitable for battery-powered and always-on monitoring in industrial and automotive systems. The SC-70-6 package fits tight PCB layouts, and the -40°C to 125°C temperature range covers under-hood and outdoor enclosures. ## Supply range and bias — fit for low-side and high-side shunts Supply voltage span from 1.7 V to 5.5 V. Input bias current is 500 pA. ## Active lifecycle — no LTB risk for production BOMs Listed as current production (active) with ROHS3 compliance. No end-of-life notice or last-time-buy schedule applies. The Zero-Drift series is an ongoing TI portfolio; the part can be specified into new designs without obsolescence concern. ## Package and mounting — SC-70-6 footprint Surface-mount SC-70-6 (also known as SOT-363). Available in Tape & Reel for automated pick-and-place or Cut Tape for prototype runs.","metaTitle":"INA190A1IDCKR Current Sense Amplifier, Zero-Drift, 45 kHz","metaDescription":"TI INA190A1IDCKR single-channel current sense amplifier, Zero-Drift series, 45 kHz GBW, 3 µV offset, 48 µA supply, SC-70-6 package.
