An example method includes outputting, by a device, a first current through a temperature sensor that is that is external to the device; determining, by the device and based on a voltage drop across the temperature sensor while the first current is flowing through the temperature sensor, a current level; outputting, by the device, a second current at the determined current level through the temperature sensor; determining, by an analog-to-digital converter (ADC) of the device, a value that corresponds to a voltage drop across the temperature sensor while the second current is flowing through the temperature sensor; outputting, by the device, a third current through a reference resistor that is external to the device; and determining, based on the value and a voltage drop across the reference resistor while the third current is flowing through the reference resistor, a temperature of the temperature sensor.
