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
Note 6. Input voltage is proportional to AVDD voltage. Vin = 0.06 x AVDD)@Mic In, Vin = 0.6 x AVDD(typ)@Line In.
Note 7. MIC Gain=20dB, IPGA=0dB, ALC1=OFF, INT(MICL)/EXT(MICR)
Note 8. IPGA=0dB, ALC1=OFF, LIN2/RIN2
Note 9. Output voltage is proportional to AVDD voltage. Vout = 0.588 x AVDD.
