With a 10 mΩ shunt carrying 1 A, the shunt drop is 10 mV; the 20 µA bias flowing through the shunt adds a 0.2 µV offset error, negligible here, but with a 1 Ω shunt the same bias adds 20 µV — comparable to the input offset itself. Housed in a 5-lead SC-70-5 (SOT-353), the part shares the same footprint as many other current-sense amplifiers from TI and other vendors — a pin-to-pin swap candidate if the BOM needs a second source.","metaTitle":"Texas Instruments INA290A2IDCKT Current-Sense Amp, SC-70-5","metaDescription":"Active-production current-sense amplifier from TI in SC-70-5. 3 µV offset, 1.1 MHz bandwidth, 2.7-20 V supply.
