A digital to analog converter convert digital data in binary format to thermometer bit vectors. A first set of the thermometer bit vectors corresponds to most significant bits of the digital data and a second set of the thermometer bit vectors corresponds to least significant bits of the digital data. Connections of first current sources corresponding to the first set of the thermometer bit vectors and second current sources corresponding to the second set of the thermometer bit vectors are dynamically and randomly alternated to a first output line and a second output line. Calibration current is applied to the second current sources so a total current of the second current sources and the calibration current is within a predetermined range of an average current of the first current sources.
