8.2.2 Detailed Design Procedure

The size of CF depends on the size of the internal sampling capacitor and the sampling frequency. The charge requirements may vary because not all ADCs have identical input stages. This general ADC application is shown as an example only.

Equation 8 shows an example of how to translate the VOUT of the TMP9A00-EP into temperature. This can be implemented in the microcontroller in control of the ADC to record temperature. Another possible way to use the TMP9A00-EP is as a temperature switch in software. The same equation can be used to translate different temperature points into discrete voltages. For example, if a desired overtemperature condition is 105 °C, the corresponding voltage output would be 628 mV.
