BOARD LAYOUT AND GROUNDING
To obtain the best performance from the SP8052, a printed circuit board with ground plane is
required. High quality, low series resistance ceramic 0.1uF bypass capacitors should be used at
the Vcc and Vs pins (pins 1 and 16). These capacitors must be located as close to the pins as
possible. The traces connecting the pins and the bypassing capacitors must be kept short and
should be made as wide as possible.
