I want to know,
What is the response time to change from 0dB to 40dB also vice-a-versa
for change in control voltage from 0.1V to 1.2V also vice-a-versa.
In my AGC circuit with two VGAs in cascade with external AGC circuit I am able to get only 350uSec attack/release times as against my requirement of 100uSec. AGC time constant is 20uSec only & RF detector used is ADL5501. Is there any limitation with VGA, I don,t see any graph or parameter to confirm. One of the graph show voltage change from 0.6V to 0.65V only.
