Its 1.3 MHz -3 dB bandwidth and 2.5 V/µs slew rate mean it tracks fast current transients — think solenoid drive recirculation or DC-DC inductor current — without the output lag that smears the measurement at the ADC input. Across a 10 mΩ shunt, that offset represents a 3 A error term; the bias current adds another 2 A of systematic error. For sub-amp sensing, a higher-value shunt or a zero-drift topology is worth evaluating. ## Supply rails and power budget Operates from 2.7 V to 20 V single supply, drawing 1.5 mA quiescent current. The wide supply range lets it share the same rail as the shunt-fed bus voltage or a lower 3.3 V ADC supply — no secondary regulator needed for the sense amplifier alone. ## Package — SOT-23-5 footprint The 5-lead SOT-23 footprint is standard for current-sense amplifiers in automotive modules; the small body keeps board area tight in ECU or BMS layouts.","metaTitle":"INA293A1QDBVRQ1 AEC-Q100 Current Sense Amp, 2.5V/µs","metaDescription":"TI INA293A1QDBVRQ1 automotive current sense amplifier, 1.3 MHz bandwidth, 30 µV offset, SOT-23-5.
