Hi Video Expert,
Our customer have confused about the explanation on your datashseet.
As for the part of the calculation Gain of VGA setting on AD9824 datasheet rev-0 page-3,
On "VARIABLE GAIN AMPLIFIER(VGA)", the value of setting x 0.0359408033826638dB
But on "SYSTEM PERORAMANCE", the value of setting x 0.0353dB
Which is correct?
0.0359408033826638dB come from as following
The case of setting value 77 is 2dB
The case of setting value 1023 is 36dB
36dB - 2dB=34dB
Please give us your advice for this.
