Note 13. When the ALC operation is enabled, maximum input voltage becomes typically (VA – 0.1V) Vpp.
Note 14. Input resistance of MIC changes from 8k to 10k by setting GAIN value, typically.
Note 15. Input resistance of LINE changes from 168k to 200k by setting GAIN value, typically.
Note 16. Input/Output voltage is proportional to VA voltage. 0.54 x VA.
Note 17. When output pin drives some capacitive load, some resistor should be added in series between output pin and
Note 18. Input resistance of OPGA changes from 63k to 158k by setting GAIN value, typically.
