Note 4. This value is (LIN+)−(LIN−) and (RIN+)−(RIN−). Input voltage is proportional to VREF voltage.
Vin = 0.58 x VREF (Vpp).
Note 5. 100µF capacitors are connected between the VREFL/R pins and AVSS.
Note 6. PSR is applied to AVDD and DVDD with 1kHz, 20mVpp. The VREFL and VREFR pins held a constant voltage.
Note 7. All digital input pins are held DVDD or DVSS.
