2.2.5.1 TMP235 Temperature Sensor

The MSP430FR2476 MCU LaunchPad development kit features a TMP235A2 temperature sensor that is accurate to ±0.5°C (typical) from –40°C to +150°C. The analog output of the TMP235 is connected to analog input A1 (P1.1) on the MSP430FR2476 through a capacitor (C7) and a pair of resistors (R12 and R13). The capacitor and resistors can be replaced if a custom RC circuit is needed. For applications that use the temperature sensor and a connected BoosterPack plug-in module, determine if there are any pin conflicts. The 3.3-V power rail can be disconnected from the TMP235 device by removing the shunt jumper at J9. This is useful in low-power applications that do not use the temperature sensor.
