[Orcnet] 165C -- anybody got _really_ high temp circuit experience?

[Steve Wetterling]

The Anadigm switched capacitor analog signal processor IC is represented to
be particularly well suited to high temp environments like this based on
existing successful applications.  What kind of analog frequencies are being
talked about?  The Anadigm technology is good for milli-Hertz bandwidths at
very low frequencies.

Please tell me more.

Subject: [Orcnet] 165C -- anybody got _really_ high temp circuit experience?

I've got a prospect who wants some work done, combining software, 
hardware, and signal processing.  The business end of this is going to 
be down in an oil well, where things are hot.  It needs to work at 150C, 
and he likes to test things at 165C.  Furthermore it's attached to a 
drilling head, so it's a high vibration/shock environment.  There are a 
lot of kinks and quirks to this (not least of which is using off the 
shelf components well beyond their maximum ratings).

I'm figuring that I'll be doing the signal processing and possibly the 
firmware.  But I don't think the customer is going to be eager to pay me 
to learn how to do the high-temp circuit design.  So if you have similar 
high temperature circuits experience, or if you know someone who has, 
let me know or point them to me.

Thanks in advance.
