ONSIDERATIONS
A 0.1µF bypass capacitor as close as possible to the V
pin is recommended for best performance.
DD
Often this can be done by placing the surface mount capacitor on the bottom side of the PC board,
directly between the V
and V
pins. Care should be taken to separate the analog and digital traces.
DD
SS
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.
