The input circuitry of the device can accurately measure signals on common-mode voltages beyond its power supply voltage, VVS. For example, the voltage applied to the VVS power supply terminal can be 5 V, whereas the load power-supply voltage being monitored (the common-mode voltage) can be as high as 36 V. Note also that the device can withstand the full 0-V to 36-V range at the input terminals, regardless of whether the device has power applied or not.
Place the required power-supply bypass capacitors as close as possible to the supply and ground terminals of the device to ensure stability. A typical value for this supply bypass capacitor is 0.1 μF. Applications with noisy or high-impedance power supplies may require additional decoupling capacitors to reject power-supply noise.
