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
F bypass capacitors should be used at the V
CC and VS pins (pins 12 and 13).
These capacitors must be located as close to the pins as possible.
The traces connection the pins to the ground plane, VCC, VS, and bypassing capacitors must be kept
short and should be made as wide as possible.
