The 100 µV input offset voltage sets the floor for measurement accuracy. The 20 µA input bias current is typical for a bipolar-input current-sense amp. ## Supply current and thermal range The 1.5 mA supply current is moderate — not a micropower part, but low enough for always-on monitoring in systems with a 100 mA-hour battery budget. The AEC-Q100 qualification (part of the Automotive series) means the part has passed the stress tests for moisture sensitivity, temperature cycling, and ESD that automotive OEMs require. For production programs that require a second source, the INA4290A2IRGVR is a four-channel current-sense amplifier in a similar voltage range, but with a 1.1 MHz GBW and 2 V/µs slew rate — not a pin-for-pin replacement, but a functional alternative if the design can accommodate a different package and channel count.","metaTitle":"TI INA281A3QDBVRQ1 Current Sense Amplifier, AEC-Q100","metaDescription":"Texas Instruments INA281A3QDBVRQ1 automotive current sense amplifier, AEC-Q100 qualified, 2.7 V to 20 V supply, 1.3 MHz GBW, SOT-23-5.
