/diy/ - Do It Yourself

>>2619313
Yeah I was designing a sample+hold circuit a few years ago, and realised the 4051 was way too bad to use for it with any size capacitor. Too big a capacitor and its high ESR wouldn't charge it all the way in the narrow charge window, and too small a capacitor and the leakage current would discharge it too quickly. No sweet spot at all.
So I made a spreadsheet out of all the analog mux ICs I could find. The DG506 is another mux with 16 channels, but it's got worse specs in general so I've no idea why someone would even use the DG5xx series aside from for the higher voltage. Pic related.

>Max Dist - the product of Ron max and Ioff max
>Seperate A/D - analogue and digital rails are seperate
Rest should be self-explanatory.
