The 15 µV input offset is low for this class, so you can resolve milliohm-level shunt drops without a large error term. ## 15 µV offset and 20 µA input bias — what they mean across a real shunt The 15 µV input offset is the dominant error at low shunt voltages. For a 1 mΩ shunt carrying 1 A, the sense voltage is 1 mV — the offset adds 1.5% error before any gain-stage drift. The 20 µA input bias current flows through the shunt itself, creating an additional voltage drop: across a 1 mΩ shunt, that is 20 nV, negligible; across a 100 mΩ shunt, it is 2 mV, which is larger than the offset. If your shunt is in the tens of milliohms or higher, budget the bias-current term in your system accuracy calculation. The 370 µA supply current is modest enough for always-on monitoring in battery-powered gear. The ROHS3 compliance is current — no exemption-driven redesign required.","metaTitle":"TI INA280A5IDCKR Current Sense Amplifier, 800 kHz, SC-70-5","metaDescription":"Texas Instruments INA280A5IDCKR current sense amplifier: 800 kHz GBW, 15 µV offset, 2.7-20 V supply, -40 to 125°C.

The A5 version has a fixed gain of 100 V/V, while the A3 is a different gain option. Check the gain setting against your shunt and ADC input range before swapping; the pin-compatibility is there, but the transfer function changes."},{"question":"Is INA280A5IDCKR available in tape and reel?","answer":"Yes, the INA280A5IDCKR is offered in Tape & Reel (TR) packaging, as well as Cut Tape (CT) for smaller quantities.
