GAIN MODE SELECTION
* If no logic inputs are applied to gain select pins, Power Down Mode is default mode.
PIN ASSIGNMENTS
BOARD LAYOUT AND GROUNDING
To obtain the best performance from the SP8064, a printed circuit board with ground plane is
required. Ground pins (pin #6) 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. A Vref
decoupling capacitor to ground should be used. 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.
