A 3 µV input offset voltage allows a smaller shunt resistor while keeping measurement error acceptable. Stack the offset with the 20 µA input bias current and the gain error over temperature when sizing the shunt — the INA290A2IDCKR's 370 µA quiescent supply current is low enough for always-on monitoring in battery-powered systems.","metaTitle":"TI INA290A2IDCKR Current-Sense Amplifier, 1.1 MHz, SC-70-5","metaDescription":"Texas Instruments INA290A2IDCKR current-sense amplifier: 2.7 V to 20 V supply, 3 µV offset, 1.1 MHz bandwidth, -40°C to 125°C, SC-70-5.
