Note 23. Input impedance of OPGA changes from 63kΩ to 158kΩ by setting GAIN value, typically.
Note 24. Input OPGL/OPGR pins. These values are measured via the following path.
Analog volume (OPGA=0dB) → Monaural Output (MOUT pin)
Note 25. Input impedance of MIN pin changes from 21kΩ to 25kΩ by setting ALC2 GAIN value, typically.
Note 26. OPGL/OPGR pins are input to –5.5dBV. These values are measured via the following path.
Analog volume (OPGA=0dB) → Monaural Output (MOUT pin)
