SBOS397F – AUGUST 2007 – REVISED DECEMBER 2015

Typical Application (continued)

The TMP102 device is a very low-power device and generates very low noise on the supply bus. Applying an RC

filter to the V+ pin of the TMP102 device can further reduce any noise that the TMP102 device might propagate

Figure 15. Noise Reduction Techniques

8.2.3 Application Curve

Figure 16 shows the step response of the TMP102 device to a submersion in an oil bath of 100ºC from room

temperature (27ºC). The time-constant, or the time for the output to reach 63% of the input step, is 0.8 s. The

time-constant result depends on the printed circuit board (PCB) that the TMP102 device is mounted. For this test,

the TMP102 device was soldered to a two-layer PCB that measured 0.375 inch × 0.437 inch.
