In the AD8310 data sheet Rev. F 6/10 the sensitivity ( slope ) is stated in several places, but with different values being given, i.e., 20, 22, 24, 25 and 26mV/dB.
I calculate that for a dc output voltage 1.8V, slopes in the range 20 to 26mV/db give a input voltage range of -18 to-39dBV.
The conversion from Vout to input dBV is essential and has to me made, but the uncertainty in slope is a problem for an acceptable tolerance on input dBV.
In my application I am currently using 24mV/dB slope. But what slope should I choose and on what basis ? Does anyone have an opinion on this ?
