10 Layout

10.1 Layout Guidelines

Figure 10-1 shows a layout recommendation with the critical placement of the decoupling capacitors. The same

reference designators are used as in the Power Supply Recommendations section. Decoupling capacitors are

placed as close as possible to the AMC3336 supply pins. For best performance, place the sense resistor close

to the INP and INN inputs of the AMC3336 and keep the layout of both connections symmetrical.

This layout is used on the AMC3336 EVM and supports CISPR-11 compliant electromagnetic radiation levels.
