Morbid curiosity, peltier cooling?

[Septimus]

What would happen if you used a peltier junction on a chipamp. Could you up rail voltages and increase power? I'm sure this wouldn't work, but I was just curious to see what people had to say on the topic.

PS. I mean use the peltier not just to heatsink, but to get the chip like, SUPER cold. You'd have to have some sort of moisture management to keep things from condensing/freezing, but other than that, any thoughts?

You would have higher power output, lower noise,wider bandwidth, higher slew rate etc. It should generally improve the specs. There may also be undesirable effects, such as altered biasing internally and mechanical stress.

Why don't you try it and see? You would need a fairly hefty heatsink to deal with all the extra power from the Peltier.

You'd be a brave man to try this, a low watt pelt. would get good, though you would still get a fair amount of condensation. IMO.

if it a < 80w pelt then i dont see condensation as an issue, unless you are in a low heat high humidity environment.
i have a 60w drinks cooler and unless there is no load on it for a few hours then it doesnt get wet
i used a heatsink with 20, 10 x 5 cm fins

Note that the cooling power (Qmax) of the Peltier must be higher than the amount of heat to be removed, otherwise it will heat instead of cooling.

peltiers are very inneficient and require large amounts of power. But they are fun to work with.

Try it out and post your results.
