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. |
