The VFO pin of CIPOS™ modules provides direct access to the NTC, which is referenced to VSS. An external pull-

up resistor connected to +3.3 V ensures that the resulting voltage can be directly connected to the

microcontroller.

Figure 26 depicts the CIPOS™ internal circuit at pin VFO. An external pull-up resistor is required to bias the NTC.
