BOARD LAYOUT AND GROUNDING
To obtain the best performance from the SP712X, a printed circuit board with ground plane is
required. High quality, low series resistance ceramic 1nF bypass capacitors should be used at
the Vcc and GND pins. This capacitor must be located as close to the pins as possible. The
traces connecting the pins and these capacitors must be kept short and should be made as
wide as possible.
