The 2 V/µs slew rate keeps the output from lagging on fast current edges, though the 20 µA input bias current means the shunt value should be kept low enough that the bias drop does not eat into the measurement headroom.","metaTitle":"TI INA280A4IDCKR Current Sense Amplifier, 850 kHz, SC-70-5","metaDescription":"Texas Instruments INA280A4IDCKR single current-sense amplifier: 2.7 V to 20 V supply, 15 µV offset, 850 kHz GBW, -40°C to 125°C.
