Use a 0.1μF bypass capacitor as close as possible to the V
performance. Often this can be done by placing the surface mount capacitor on the bottom side of the
PC board, directly between the V
digital traces. Sensitive traces should not run under the device or close to the bypass capacitors.
A dedicated plane for analog ground helps in reducing ground noise for sensitive analog signals.
