9 Power Supply Recommendations

The device input circuitry accurately measures signals on common-mode voltages beyond the power-supply

voltage, VS. For example, the voltage applied to the VS+ power-supply pin can be 5 V, whereas the load power-

supply voltage being monitored (VCM) can be as high as 26 V. The device can withstand the full –0.2-V to +26-V

range at the input pins, regardless of whether the device has power applied or not.

Power-supply bypass capacitors are required for stability and must be placed as closely as possible to the supply

and ground pins of the device. A typical value for this supply bypass capacitor is 0.1 µF. Applications with noisy

or high-impedance power supplies can require additional decoupling capacitors to reject power-supply noise.
