Note 6. This value is (LIN+)−(LIN−) and (RIN+)−(RIN−). Input voltage is proportional to VREF voltage.
Vin = 0.56 x VREF1/2 (Vpp).
Note 7. PSR is applied to AVDD1/2 and DVDD1/2 with 1kHz, 20mVpp. The VREFP1 and VREFP2 pins held a constant
voltage.
Note 8. All digital input pins are held DVDD1/2 or VSS3/4.
