8.2.3 Application Curve

Figure 8-4 shows the step response of the TMP112 to a submersion in an oil bath of 100ºC from room temperature (25ºC). The time-constant, or the time for the output to reach 63% of the input step, is around 1.2s for both packages. The time-constant result depends on the printed-circuit board (PCB) size that the TMP112 is mounted. For this test, the TMP112 is soldered to a two-layer PCB that measured 0.5 inches × 0.5 inches.
