INA250A1 - Texas Instruments

INA250A1 Zero-Drift Current-Shunt Monitor

The 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 highside current-shunt monitor that allows an external reference to be used t.
