8.5 Layout

8.5.1 Layout Guidelines

Figure 8-6 shows a layout recommendation with the critical placement of the decoupling capacitors (as close as

possible to the AMC1301 supply pins) and placement of the other components required by the device. For best

performance, place the shunt resistor close to the INP and INN inputs of the AMC1301 and keep the layout of

both connections symmetrical.
