The 15 µV input offset voltage sets the floor on the minimum shunt voltage you can resolve — at a 10 mΩ shunt, that offset corresponds to 1.5 mA of apparent current error, which matters for low-current monitoring in battery-powered or precision-load applications. Supply range spans 2.7 V to 20 V, letting it run directly off a 3.3 V, 5 V, or 12 V rail without an extra LDO. ## Slew rate and response time for overcurrent detection The 2.5 V/µs slew rate determines how fast the output can swing when a fault current appears. For a 10 mΩ shunt and a 50 A step, the output jumps 500 mV; at 2.5 V/µs, the output reaches that level in 200 ns — fast enough to trigger a comparator or ADC interrupt before the current exceeds the silicon limit. If your application needs sub-microsecond fault response, this part keeps the signal chain tight.","metaTitle":"TI INA293B2IDBVR Current Sense Amplifier, 1.3 MHz, SOT-23-5","metaDescription":"Texas Instruments INA293B2IDBVR current sense amplifier: 2.7 V to 20 V supply, 15 µV offset, 2.5 V/µs slew rate, -40°C to 125°C.
