BOARD LAYOUT AND GROUNDING

To obtain the best performance from the SP8042, a printed circuit board with ground plane is required.

Both ground pins (pins #9 and #16) should be connected to the ground plane. High quality, low series

resistance ceramic 0.1

µF bypass capacitors should be used at the V

These capacitors must be located as close to the pins as possible.

short and should be made as wide as possible.
