I was wondering if anyone out there has had the pleasure of using this variant?

I'm using it and I'm have some problems with the internal temperature sensor. The reading at 25 deg C should be 600mv. It has a Temperature Coefficient of -3mv/degC. I'm reading values of 640mv @25degC which means the device appears to be cooler than the ambient air...hardly. I've slowed the aquisition time and the conversion time to th maximum time allowed using a 11.0592MHz crystal.

Anybody out there with ADUC812 experience???

Thanks in advance.
