Since there is a discussion about ovenized oscillators, here's something for restoring the broken symmetry.
I am planning to build an electrometer based on ADA4530-1. Due to the insanely low leakage currents required, a regular PCB seems to be a no-go. This instrument will be a one-off, so I can safely ignore the usual DFM rules. Namely, I am considering a dead-bug arrangement of the critical components and using air as insulation. For mechanical stiffness and reasonable thermal conductance to avoid gradients, a ceramic base plate would be one idea. But the ceramic can be a part of a TEC module. Question: would it be worth the trouble to cool the ADA4530-1 (and maybe the ADC and the reference) to ~10 degrees C, in terms of noise/thermal input offset etc.?
Best regards, Piotr
