INA250/INA250-Q1 Zero-Drift Current-Shunt Monitor

Texas Instruments INA250/INA250-Q1 Bi-Directional Zero-Drift Current-Shunt Monitor is a voltage-output, current-sensing amplifier that integrates an internal shunt resistor. This enables high-accuracy current measurements at common-mode voltages that can vary from 0V to 36V, independent of the supply voltage. Texas Instruments INA250/INA250-Q1 device is a bidirectional, low- or high-side current-shunt monitor. It allows an external reference to be used to measure the current flowing in both directions through the internal current-sensing resistor sensor. The integration of the precision current-sensing resistor provides calibration equivalent measurement accuracy with ultra-low temperature drift performance. It also ensures an optimized Kelvin layout for the sensing resistor is always obtained. The INA250-Q1 devices are AEC-Q100 qualified for automotive applications.
