PRINTED CIRCUIT BOARD (PCB) LAYOUT
GUIDELINES
It is recommended that the ground planes for the digital
and analog sections of the 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 PGA2311.
The PGA2311 is mounted so that it straddles the split
between 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.
