Anybody has a reference for a simple ADC board with an spdif output? I prefer coax output but optical is also an option. 16/44.1 is plenty for the use I have in mind.
I'd like to build one into my preamp so that all analog sources get converted before switching and sending out of the preamp. So it is for my fm radio, an old tape deck, turntable etc. DAC board are 13 a dozen but ADC boards look scarce.

A cheap ADC to SPDIF board is probably going to sound bad. First, a good ADC is like a good dac, to be really good takes some good surrounding circuitry. Then the other problem is that SPDIF is jittery. So, if its a cheap board then its probably going to be kind of like garbage in, garbage out. Is that what you want for your turntable sound, etc.?
Then there is the problem that boards like that may not be very common. If you want an ADC input, and a SPDIF output then a cheap USB recording interface such as Scarlett 6i8 is at least pretty good for the money.

Putting an 6i8 into my preamp is a bit silly I feel. It is just for radio and the occasional lp or cassette.
I haven't said "dead cheap" either. Just something simple, basic for occasional listening. If I want to record an lp to the pc I'll use the RME setup but that is in the study at the other end of the appartment.

I would not be afraid to test out e.g. https://www.aliexpress.com/item/1005006565291310.html along with any spdif transmitter, e.g. https://www.aliexpress.com/item/1005007622347810.html
If it would need to be really cheap, you could buy this and get the PCB out of the enclosure.

Mind you, I know from experience that an ADC that looked remarkably similar to this one had a reasonable ADC chip on board (not up to Mark's standards, but not very bad either), but the manufacturer had completely left out the analogue anti-aliasing filter/input buffer application circuit. If the same holds for this one, an upgrade would be to add a perfboard with the normal input application circuit recommended in the ADC chip datasheet.
