Hello ADI
Our customer has a question for AD8351.
A calculated Av(dB) value does not match GAIN(dB) on the figure 38.
This calculated Av(dB) is used for the part of "GAIN ADJUSTMENT" of page12 on the data sheet.
For example, a calculated Av was 23.84 dB when RL=150 ohm, RG=10 ohm, Rf=350 ohm.(GAIN on the figure 38 is about 25 dB)
How do we need to understand this calculation?
For example we made graph for Av vs RG.
(RL=150 ohm/500 ohm ,Rf=350 ohm for internal , and we calculate for RG(5.6)=RG*5.6) .
But these calculated Av(dB) is a little smaller than data on the figure 38. (please see to attachment)
Best regards
Nozawa
