* N/C pins must be connected

to GND(to Analog GND if

possible).

NOTES:

1 pin #10 = pin #19(internally connected).

2. Do not tie up Vp and VDD

: Vp is the source of digital noises. The power for analog part is supplied by VDD. If Vp and VDD are tied together,

noisy Vp corrupts the power source for the analog part.
