INA250 Current-Sensing Amplifier

36 V low-/high-side bi-directional zero-drift current sense amp with precision internal shunt resistor from Texas Instruments

Image of Texas Instruments INA250 Current-Sensing AmplifierTexas Instruments' INA250 is a voltage-output, current-sensing amplifier family that integrates an internal shunt resistor to enable high-accuracy current measurements at common-mode voltages that can vary from 0 V to 36 V, independent of the supply voltage. The device is a bidirectional, low- or high-side current-shunt monitor that allows an external reference to be used to measure 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 and ensures an optimized Kelvin layout for the sensing resistor is always obtained.
