Note. All the analog characteristics shown above are the values obtained on the DMB-D1, Yamaha's YDA131
evaluation board.
The characteristics may vary according to the coils and capacitors that are used, pattern layout and other
factors.
These values do not guarantee the characteristics at VDD=3.3±0.5V.
