> The ADS7953 is somewhat of a ferrari, whereas the MCP3208 feels like a Toyota, simple to use, unimpressive performance.

What about the AD9226? It only has a single channel but can do up to 65 MSa/s at 12 bits. I bought one as a module for around $12 on AliExpress to experiment with software decoding of analog video. I only run it at 20 MSa/s and only use 8 bits because, funnily enough, the limiting factor is the speed at which I could get the data into my laptop. I connected it to a Raspberry Pi Zero and use the SMI peripheral as described here: https://iosoft.blog/2020/07/16/raspberry-pi-smi/



That is very interesting, especially using SMI to talk to rpi. Never seen SMI used in anger before.


I've seen it used as a multi channel logic wave generator. Basically a 16bit wide relatively fast DMA.


For the curious: that blogpost does not mention the Pi model explicitly, but one of the links refers to BCM2835. This means Raspberry Pi Model 1.


The article does reference pi 3b and zero W.


I've used it on pi1-4. Not sure if Pi5 has SMI on its southbridge
