Note 8. PSR is applied to AVDD and DVDD with 1kHz, 50mVpp. This is the value of convoluted sinusoidal voltage of

1kHz and 50mVpp when the VREFH pin is held +5V.

Note 9. This is a value when the frequency range is 20Hz ~ 20kHz assuming an external capacitor is 10uF±30% and

GDNIN1/2 amplitude is 100mVpp.
