The INA185 is a 26-V common-mode current-sensing amplifier used in both low-side and high-side configurations. This specially-designed, current-sensing amplifier accurately measures voltages developed across current-sensing resistors on common-mode voltages that far exceed the supply voltage powering the device. Current can be measured on input voltage rails as high as 26 V, and the device can be powered from supply voltages as low as 2.7 V.
