10 Power Supply Recommendations

The input circuitry of the INA203-Q1 can accurately measure beyond the power-supply voltage, VS. For example, the VS power supply can be 5 V, whereas the load power-supply voltage is up to 80 V. The output voltage range of the OUT terminal, however, is limited by the voltages on the power-supply pin.
