7.2.2 Detailed Design Procedure

The AMC3301 requires a single 3.3-V or 5-V supply on its low-side. The high-side supply is internally generated by an integrated DC/DC converter as explained in the Isolated DC/DC Converter section.

The ground reference (HGND) is derived from the terminal of the shunt resistor that is connected to the negative input of the AMC3301 (INN). If a four-pin shunt is used, the inputs of the AMC3301 are connected to the inner leads and HGND is connected to one of the outer shunt leads. To minimize offset and improve accuracy, set the ground connection to a separate trace that connects directly to the shunt resistor rather than shorting HGND to INN directly at the input to the device. See the Layout section for more details.
