Note 3. Full-scale voltage (0dB). Output voltage scales with the voltage of VDD, Vout = 0.85 × VDD (typ).
Note 4. Full-scale voltage (0dB). Output voltage scales with the voltage of VDD, Vout = 0.67 × VDD (typ).
Note 5. For AC-load.
Note 6. RSTN bit= “1”, PW bit= “1”
Note 7. All digital input pins are fixed to VDD or VSS.
