* N/C pins must be connected
to GND(to Analog GND if
possible).
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.
