/diy/ - Do It Yourself

Sounds like tuning an array of caps is a pointless exercise in this case.
I did notice that the thermocouple is very sensitive to trace length, so I made sure to keep the traces as tight as possible on the prototype perf board, which I plan to translate to the PCB.

For all intents and purposes, I will just place a 0.1μf cap near the AD595

I should add that I plan on making a buck converter to power the Teensy with a 3.3V (stepped down from the 5 Vcc). I want to power it independently from the USB port (didn't depict that in my original circuit).
Will I need to worry about decoupling capacitors for the 3.3V supply? Judging by the Teesny's schematic, it doesn't look like that MKL02Z32VFG4 or the SD Card is decoupled at all from the 3.3V input supply. The MCU itself looks like it has sufficient decoupling otherwise.
