Figure 3-3 shows the temperature sensing circuit used to measure the PCB temperature. The TMP61 silicon linear thermistor has a linear positive temperature coefficient (PTC) that results in a uniform and consistent temperature coefficient resistance (TCR) across a wide operating temperature range. The TMP61 offers higher accuracy and easier speed acquisition compared to NTC. (No temperature form is required.)
