Apologies for the off topic post, but I know there some very knowlegable people in this forum that might know the answer.
Do any of you know much about CMOS sensor ICs. I am having to do some thermal calculation on a system that has one of this implimented. Its a high end CMOS sensor, that draws 4w of power. The only problem if, when I model this at 4w the temperature gets crazily hot (in free air), but in reality it only gets 40c above ambient at the 4w.
Im therefore wonder if all 4w is actually converted in to heat, or maybe CMOS / CCD sensors are different in the way they use the power and in fact a lot less is converted in to heat?
