SLUSAS3C April 2014 – November 2017
The TS1 input is enabled with an internal 18-kΩ (Typ.) linearization pull-up resistor to support the use of a 10-kΩ (25°C) NTC external thermistor, such as the Semitec 103AT-2. The NTC thermistor should be connected between VSS and the individual TS1 pin. The analog measurement is then taken via the ADC through its input multiplexer. If a different thermistor type is required, then changes to configurations may be required.
