STEADY HEAT CONDUCTION
s at tem-perature T s and the surrounding surfaces at some average temperature T surr can be expressed as rad es A s ( ) h rad A s (T s T surr) (W) (3–9) where R rad (K/W) (3–10) is the thermal resistanceof a surface against radiation, or the radiation resistance, and h rad es( (T s T surr)(W/m2 K) (3–11) is the radiation heat transfer ...

www.analog.comThe LT1236 combines both superior accuracy and tem-perature coefficient specifications without the use of high power, on-chip heaters. The LT1236 references are based on a buried zener diode structure which eliminates noise and stability problems with surface breakdown devices. Further, a subsurface zener exhibits better temperature
