PCB Layout Guidelines
This section provides general practical guidelines for PCB layouts that use various power and ground
traces. Designers should note that these are only "rule-of-thumb" recommendations and the actual results
are predicated on the final layout.

5.1
Differential Signals
The two input pins of the LMP8601 form a differential pair that must be handled following the rules given
below.
below.
•
Keep both signals coupled by routing them closely together and keeping them of equal length.
•
Do not allow any other signal in between these two signals of the differential pair.
•
Keep all impedances in both traces of the signal equal.
5.2
Power, Ground and De-Coupling
Keep the power supply de-coupling capacitor close to the power supply pin (V
S
of the part.)
Make sure all return currents of the signals can flow next to the originating signals
