11.1 Layout Guidelines
A layout recommendation showing the critical placement of the decoupling capacitors (as close as possible to the
AMC1301-Q1 device) and placement of the other components required by the device is shown in Figure 55. For
best performance, place the shunt resistor close to the VINP and VINN inputs of the AMC1301-Q1 device and
keep the layout of both connections symmetrical.
