Hi friends, does any of you before used ADA2200 to make lock-in amplifier. I read that its ready board to which you need to add some additional elements to make lock-in amplifier. If anyone knows, your help will be appreciated. Thank you in advance.
 

Hi,

I always used some standard analog switch/mux and some Rs and some Cs.
No special hardware needed.

If you want to amplify the signal, then almost any OPAMP will do.

Show us a draft of your input signals and the expected output signal.
A signal flow chart and an electrical specification of the input and output signals would be useful, too.
