PRINTED CIRCUIT BOARD LAYOUT
GUIDELINES
It is recommended that the ground planes for the digital
and analog sections of the printed circuit board (PCB) be
separate from one another. The planes should be
connected at a single point. Figure 6 shows the
recommended PCB floor plan for the PGA2310.
The PGA2310 is mounted so that it straddles the split be-
tween the digital and analog ground planes. Pins 1 through
8 are oriented to the digital side of the board, while pins 9
through 16 are on the analog side of the board.
