9 Power Supply Recommendations

The input circuitry of the INA20x devices can accurately measure beyond the power-supply voltage, Vs. For example, the Vs power supply is 5 V, whereas the load power-supply voltage is up to 80 V. However, the output voltage range of the OUT pin is limited by the voltages on the power supply pin.

9.1 Output vs Supply Ramp Considerations

Figure 36, Figure 37, and Figure 38 show the typical output voltages for high and low-side configurations with the given ramp supply voltage. These fluctuations on the output during power-up may require a controller to incorporate a blanking time to disregard the artifacts.
