Note 13. Input voltage is proportional to AVDD voltage. Vin = 0.06 x AVDD (typ)@MGAIN1-0 bits = “01” (+20dB),
Vin = 0.6 x AVDD(typ)@MGAIN1-0 bits = “00” (0dB)
Note 14. MGAIN1-0 bits = “01” (+20dB)
Note 15. MGAIN1-0 bits = “00” (0dB)
Note 16. Output voltage is proportional to AVDD voltage. Vout = 0.6 x AVDD (typ)@LOVL bit = “0”.
Note 17. Output voltage is proportional to AVDD voltage. Vout = (RCP) − (RCN) = 0.59 x AVDD (typ)@LOVL bit =
“0”, −6dBFS.
