Note 7. This value is the full scale (0dB) of the input voltage. Input voltage is proportional to AVDD
voltage. Vin = 0.8 x AVDD (Vpp).
Note 8. This value is the full scale (0dB) of the output voltage. Output voltage is proportional to AVDD
voltage. Vout = 0.76 x AVDD (Vpp).
Note 9. When LOUT/ROUT drives some capacitive load, a 220 resistor should be added in series
between LOUT/ROUT and capacitive load. In this case, LOUT/ROUT pins can drive a capacitor
of 400pF.
Note 10. For AC-load
Note 11. VCOM pin is connected to VSS1 pin with 1µF±50% capacitor in series.
When LDOE pin = “L”, PSR is applied to AVDD, VDD18 and TVDD with 1kHz, 50mVpp.
When LDOE pin = “H”, PSR is applied to AVDD and TVDD with 1kHz, 50mVpp.
