Note 16. When ALC1 is enabled, maximum input voltage becomes typically (VA – 0.13V) Vpp.
E.g. 2.67Vpp = -0.5dBV @ VA = 2.8V
Note 17. Input impedance of MIC changes from 8k
to 10k
by setting GAIN value, typically.
Note 18. Input impedance of LINE changes from 168k
to 200k
by setting GAIN value, typically.
Note 19. Input/Output voltage are proportional to VA voltage. 0.54 x VA.
Note 20. Input from LIN/RIN pins. AIN = “1”. IPGA = 0dB.
Note 21. Input from MIC_IN_L and MIC_IN_R pins. AIN = “0”. IPGA = +26dB.
Note 22. When output pin drives some capacitive load, some resistor should be added in series between output pin and
capacitive load.
