BOARD LAYOUT AND GROUNDING

To obtain the best performance from the SP8043, a printed circuit board with ground plane is

required. Both ground pins (pins #6 and #13) should be connected to the ground plane. High

quality, low series resistance ceramic 0.1uF bypass capacitors should be used at the Vcc and

Vref pins (pins #3 and #14). These capacitors must be located as close to the pins as possible.

The traces connecting the pins to the ground plane, Vcc, Vref, and bypassing capacitors must

be kept short and should be made as wide as possible.
