Tool/software:
Dear Specialists,
My customer is considering VCA821 and has a question.
I would be grateful if you could advise.

In the case of analog VGA, the output voltage may fluctuate greatly due to noise in the gain adjustment voltage.
In the case of VCA821, can noise at VG pin be reduced internally?
Or does the noise applied to the VG pin directly affect the gain?
In this case, the control voltage must be kept very clean.

I appreciate your great help in advance.
Best regards,
Shinichi
