Anyone work with this guy?
I have five on order that should be getting here this week... I'd be interested to hear if anyone has too, or if I get it working beforehand.. Perhaps I'll share.. =)

Is there a reason you need to use an analog sensor over a digital one? A digital one such as LM75B or DS1631 will be much easier and won't need to be calibrated with a pot.(only reason I can really see maybe is waterproof or cost-sensitive application... or maybe thermocouple compensation)Otherwise, its just like any other sensor, plug into ADC and calibrate with pot.
I'm using them because they are cheap... $1.35 in quantity, and I don't need a particularly accurate temperature reading...just a too hot or not too hot gauge.. The 1631 or even 1820 are wonderful, but way overkill for some apps... (my two cents...)

http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=568-4769-1-ND92 cents for singles.. 29 cents in quantity...plus you don't need a pot...granted, its not the easiest to use package in the world, there are similar ones in DIP package (similar cost).=p
And it's I2C even! I'm sold. The TSSOP8 or even SO8 would be easy to work with...
Thanks, Michael! Glen....hope I didn't hijack this too much..and maybe you found this info useful too.... =)
You can get the TSSOP8 here in smaller than 2500piece quantities.... less than 1$ea... http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=568-4768-1-ND
or here in the 8-SOIC package for ~1$ea.... http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=568-4688-1-ND
OR... if you like smaller prices....Try $0.46ea (singles) in the TSSOP-8 package...at Mouser.!!! http://www.mouser.com/ProductDetail/NXP-Semiconductors/LM75BDP118/?qs=sGAEpiMZZMsrT%252b%252bRgDw3Nt0dGHVb6SM3HxNM6J1hXoo%3d
I just noticed while ordering some of these LM75s from mouser, I made a quick check and sure enough...SparkFun has a nice break out board for the SSOP8 package to dip... Anyone notice if there is there a footprint difference between TSSOP and SSOP?
(If it works, and if you don't mind paying $2.95 for the breakout when the part only costs 0.46).. but that's the cost of convenience!
