7.3 Power Supply Recommendations

The input circuitry of the INA185-Q1 allows for accurate measurements beyond the power-supply voltage, VS. For example, VS can be 5V, whereas the bus supply voltage at IN+ and IN– can be as high as 26V. However, the output voltage range of the OUT pin is limited by the voltages on the VS pin. The INA185-Q1 also withstands the full differential input signal range up to 26V at the IN+ and IN– input pins, regardless of whether or not the device has power applied at the VS pin.
