Note 8. This value is (AINnP)−(AINnN) that the ADC output becomes full-scale (n=1~8). Input voltage is
proportional to VREFH−VREFL.
Vin = 0.56 × (VREFHm−VREFLm) [Vpp]. (m=1~4)
Note 9. PSRR is applied to AVDD, TVDD with 1kHz, 20mVpp sine wave. The VREFH1~4 pins are held to the
same voltage.
Note 10. All digital inputs are fixed to TVDD or TVSS.
