The small footprint suits space-constrained current-sense nodes on multi-layer boards. ## Precision and power budget With a 2 µV typical input offset voltage and 500 pA input bias current, the INA190A1IRSWR resolves sub-millivolt drops across a shunt resistor without significant error from bias currents — critical for low-side sensing where the shunt voltage is tens of millivolts. Drawing only 40 µA supply current, this amplifier fits battery-powered or energy-harvesting designs where every microamp counts. The rail-to-rail output swings close to the supply rails, preserving dynamic range at low supply voltages down to 1.7 V. ## Bandwidth and response time The 45 kHz gain-bandwidth product and 0.25 V/µs slew rate limit the INA190A1IRSWR to DC and low-frequency current monitoring — suitable for motor winding currents, battery charge/discharge profiles, or DC rail sensing, but not for fast-switching power converter loops above a few kilohertz.","metaTitle":"Texas Instruments INA190A1IRSWR Current Sense, 45 kHz","metaDescription":"Active Texas Instruments INA190A1IRSWR current-sense amplifier, 2 µV offset, 40 µA supply, -40 to 125°C.
