Note 8. This value is (LIN+)−(LIN−) and (RIN+)−(RIN−). Input voltage is proportional to VREF voltage.
Vin = 0.58 x VREF1/2 (Vpp).
Note 9. PSR is applied to AVDD1/2 and DVDD with 1kHz, 20mVpp. The VREFP1 and VREFP2 pins held a constant
voltage.
Note 10. All digital input pins are held DVDD or VSS3/4.
