Note 4. Output voltage is proportional to AVDD voltage. Vout = 0.75 x AVDD.
Note 5. Comparator Voltage Level is proportional to AVDD voltage. Vout = 0.05 x AVDD(min), 0.075 x AVDD(max).
Note 6. When IPGA Gain is changed, this typical value changes between 8k
and 11k
.
Note 7. Input voltage is proportional to AVDD voltage. Vin = 0.06 x AVDD.
Note 8. Output voltage is proportional to AVDD voltage. Vout = 0.588 x AVDD.
Note 9. Output voltage is proportional to AVDD voltage. Vout = 1.2 x AVDD(typ)@MOGN=0,
0.094 x AVDD(typ)@MOGN=1 at Full-differential output.
Vout = 0.6 x AVDD(typ)@MOGN=0, 0.047 x AVDD(typ) @MOGN=1 at Single-end Output.
