RT1 ~ RT3). The internal reference voltage source via a resistor UREF REX1 ~ REX3 were given three thermistor power supply, the voltage drop across the thermistor respectively supplied THER1 ~ THER3 pins. Temperature transistor can be used CMPT3904, SST3904, KST3904-TF, SMBT3904, FMMT3904CT-ND models.
