I am wondering about using a AD5206 to provide a variable gain signal (X or Y) and offset-signal (Z) to a AD835.
It will be used to control a high-speed video signal,
and I am wondering about output impedance of AD5206 vs input impedance of AD835.
The AD835 datasheet does mention loading, but will it be toward a "clean" point? or can parts of the video be injected out the input?
There will be used a capacitor on the output(Wiper) of AD5206, but is there any other things to beware of (ex power control signal with a opamp)? The gain and offset signals will mostly stay at fixed values.
