A sensor circuit, e.g., a circuit for use with a sensor that develops a current responsive to temperature, includes a digital to analog (D/A) comparison circuit having an analog sense current input and a digital input, the D/A comparison circuit operative to compare a digital value at the digital input to a sense current at the sense current input and to responsively generate a comparison signal. The sensor circuit further includes a control circuit configured to provide digital values to the digital input of the D/A comparison circuit responsive to the comparison signal and to generate a digital output corresponding to the sense current.
