Note 4. Output voltage is proportional to AVDD voltage. Vout = 0.75 x AVDD.
Note 5. When IPGA Gain is changed, this typical value changes between 8k
and 11k
(LIN1, RIN1), 48k
and 66k
(LIN2, RIN2).
Note 6. Input voltage is proportional to AVDD voltage. Vin = 0.06 x AVDD)@Mic In, Vin = 0.6 x AVDD(typ)@Line In.
