T he thermal mass ofthe T M P01 package and the degree of thermal coupling to the surrounding circuitry are the largest factors in determining the rate ofthermal settling, which ulti- mately determines the rate at which the desired temperature measurement accuracy may be reached. T hus, one must allow sufficient time for the device to reach the final temperature. T he typical thermal time constant for the plastic package is approximately 140 seconds in still air! T herefore, to reach the final temperature accuracy within l%, for a temperature change of60 degrees, a settling time of5 time constants, or 12 min- utes, is necessary.
