Looking for an ADC that works stand alone without a computer.

I was thinking about exactly that last night. I wanted to write an email in the next few days anyway and ask if you can hack the Cosmos ADC and output the digital signal as SPDIF or i2s. It would be the ideal device and the values could hardly be better.I read recently in the cosmos thread that it can be modified to output spdif. Not sure if it can work standalone though, but you can go and ask @IVX don't know if it has the functionality or price point you need, but performance I am sure will be good enough

Used EMU 0404 USB?

I think your best choice is what Amir suggested, RME BabyFace Pro. It will do both SPDIF Toslink and ADAT. It can be setup and then run without a PC. It is bus powered, but has an optional jack that can power it without a PC.

No, it works standalone. Here's a Samsung Galaxy S8 headphone out into EMU 0404 USB running standalone outputting SPDIF to an RME ADI-2 DAC FS. No computer in sight.
This misses some of your requirements. Maybe still worthwhile:

Will be quite cheap because only available as used. Balanced DB25 input, can be adapted to RCA or whatever. Has 8x AES out and only needs power to operate, not a single button. Shows up used for around 300 EUR.

The Genelec AD9200A Analog to Digital Converter is no longer in production.

I prepared the SPDIF-ready FW for Cosmos ADC, so, you need just add a TOSLINK.
Original Cosmos ADC has no that pin on the header, and would not be easy to tie the SPDIF directly to the ES9822 pin, but Cosmos ADCiso has that pin on the header.
a use case for Eitr 2 ?
as $99 DDC, input USB-C, designed specifically to interface computers, tablets, or phones
reclocks the signal and provides S/PDIF both coax and Optical outputs, for devices that do not have USB inputs, plus AES/EBU (AES3) outputs, all concurrent
turns into a digital preamp for $50 more

I am quite happy with the Minisdp Pocket Adc. It has a very useful 100k input impedance and a 2V sensitivity making it simple to interface with current analog equipment. The 100k load makes it easy to attenuate the input signal with something like a 5k potentiometer to prevent digital clipping. It only has RCA input and Spdif coaxial and optical outputs. I don't want actual computers in my audio environment. I use it to splice my old turntable into a Marantz ND 8006 streamer / CD player.
And for a USB output DDC, I think uniquely when USB host mode is required

SPDIF Optical TOSlink to USB Converter takes a TOSlink input and outputs it as USB audio, working without a computer involved
16-bit/44.1kHz up to 24-bit/96kHz
I love these specialised tools, small and not pricey but high SQ, modularity to help handle many use cases rather than all-in-ine boxen costing the earth

Apparently I was wrong, the product page at HiFiMeDIY clearly states while the USB is a generic Class interface, it does require a computer to act as host.
Back to the drawing board, further reco's wanted

WiiM Pro has RCA in and S/PDIF out. Pro Plus, likewise, and it tested better.
Yes but pricey if you just want signal conversion!

ISO DDCs with USB Output, act in USB Host mode, work without a computer
I thought one of the HiFiMe devices worked like this, turns out I was mistaken got bad info. Not looking for an ADC or audio interface, or hybrid DAC / mixers etc, but if these do exist with this capability, please do post. Technically the Wiim devices' USB output do qualify, but those are in...
