NOTES:
1. AGND and DGND should be connected as close to the WM8716 as possible.
2. C

should be positioned as close to the WM8716 as possible.
3. Capacitor type used can have a big effect on device performance. It is
recommended that capacitors with very low ESR are used and that ceramics
are either NPO or COG type material to achieve best performance from the
WM8716.
