Abstract: A temperature sensor includes a first selection circuit outputting one among temperature signals in response to a selection code. A reference voltage generator generates a reference voltage. A control circuit generates a control signal. A second selection circuit outputs the reference voltage and the temperature signal in response to the control signal indicating a voltage conversion condition is satisfied and outputs only the temperature signal in response to the control signal indicating the voltage conversion condition is not satisfied. A converter converts the reference voltage to a voltage digital code and the temperature signal to a temperature digital code in response to the control signal indicating the voltage conversion condition is satisfied and converts only the temperature signal to the temperature digital code in response to the control signal indicating the voltage conversion condition is not satisfied.
