Note 10. In case of full-differential input, MGAIN=0dB (min) and AVDD=2.4V (min).
Note 11. Output voltage is proportional to AVDD voltage. Vout = 0.8 x AVDD (typ).
Note 12. Comparator Voltage Level is proportional to AVDD voltage. Vth = 0.05 x AVDD(min), 0.075 x AVDD(max).
Note 13. Input voltage is proportional to AVDD voltage. Vin = 0.053 x AVDD (typ)@MGNL3-0=MGNR3-0 bits =
“CH” (+21dB), Vin = 0.6 x AVDD(typ)@MGNL3-0=MGNR3-0 bits = “5H” (0dB).
Note 14. MGNL3-0=MGNR3-0 bits = “CH” (+21dB).
Note 15. MGNL3-0=MGNR3-0 bits = “5H” (0dB).
