INA250A2PW .

产品概述

The INA250A2PW is a Voltage-Output, Current-Sensing Amplifier that integrates an internal shunt resistor to enable high-accuracy current measurements at common-mode voltages that can vary from 0 to 36V, 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.
