The input circuitry of the INA185 allows for accurate measurements beyond the power-supply voltage, V_S. For example, V_S can be 5 V, whereas the bus supply voltage at IN+ and IN– can be as high as 26 V. However, the output voltage range of the OUT pin is limited by the voltages on the VS pin. The INA185 also withstands the full differential input signal range up to 26 V at the IN+ and IN– input pins, regardless of whether or not the device has power applied at the VS pin.
