May I set the ADL5330 gain PIN using AC signal?
I just saw the DC setting in spec.
If it is OK for AC setting, how about the frequency limit?
Thanks a lot!
The bandwidth of the gain control input is kept low so that the main signal is not degraded by any noise on this input. The bandwidth of the gain control input can be seen in figure 8 in the datasheet, pretty flat out to where it falls off at around 10kHz. There is a large spike in the response around 8kHz, looks like the overall response is underdamped,
