Note 10. Maximum input voltage of MIC+ and MIC
pins are proportional to AVDD voltage. Vin = 0.03 x AVDD(typ).
Note 11. When IPGA Gain is changed, this typical value changes between 8k
and 11k
.
Note 12. Input voltage is proportional to AVDD voltage. Vin = 0.06 x AVDD.
Note 13. Output voltage is proportional to AVDD voltage. Vout = 1.2 x AVDD(typ)@MOGN2-0 bits = “111” at
full-differential output. Vout = 0.6 x AVDD(typ
)
@MOGN2-0 bits = “111” at single-ended Output.
