Hello, I am trying to identify an IC to perform the function above, with I/Q outputs. Carrier frequency is 125kHz so the usual suspects (RF demodulators) are out of question.
The closest thing I found that could work was the AD2200 but is has been discontinued years ago.
I am considering implementing it with analog switches and amp. ops., but before reinventing the wheel, I would like to know if there is some more integrated solution I may be missing.
Or, if not a fully integrated solution is available, some non obvious use of some IC(s) that could make a more integrated/sound/stable implementation instead of the analog switches/amp. ops approach.
TIA for any help.
