24-QFN

24 PIN Quad Flat Non-leaded

(Digital)

(Analog)

* 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.
