ANALOG CHARACTERISTICS (AUDIO)
(Ta=25
°
C; AVDD = VVDD1-2 = 5V, DVDD =3.3V; AVSS = VVSS1-3 = DVSS = 0V; Signal Frequency=1kHz,
Measurement Frequency=20Hz

Input Reception Adjustment Gain Step (Note: 11)
Note: 5. Connected GND1-7 to GND using a capacitor for AC-coupling.
Note: 6. The Input Voltage meets S/(N+D)>82dB
Note: 7. Between all channels of LIN1-7 and RIN1-7.
Note: 8. The output resistance of audio output (LOUT1-3 and ROUT1-3) are less than l0
Ω
(typ).
Note: 9. Applied to AVDD, VVDD1-2 and DVDD with a sine wave (1kHz, 50mVpp).
Note: 10. Detect an instant value. 31dBV=+40mV0p. If the input voltage is smaller than the detection reception value, the
signal isn’t detected, and if the input voltage is larger than the detection reception value, the signal is detected.
The input reception value is proportional to AVDD voltage as of 0.008 x AVDD V0p(typ).
Note: 11. Input Reception Adjustment Gain is +6dB
～
-6dB.
