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. 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.
