[BC] Novus Development?

[Mike McCarthy]

  After looking at this data sheet, this device might prove to be a 
challenge with some remote controls and sensors without a conversion 
scale or algorithm despite it being nearly linear.  Instead of 10mV/deg. 
with the LM 34, this device runs 20mV/deg. starting at 0.4V at 32 deg. 
F. At least with the LM34, you can direct read the temperature by merely 
shifting the decimal place over two points.

I will admit, I WOULD prefer to see that 10mV/deg. scale start at 1V to 
permit below zero indication without the need for a Bi-polar supply.
