A self-calibrating digital-to-analog converter (DAC) is disclosed. The self-calibrating DAC includes an input port, a non-binary DAC, an ADC to receive an output of the non-binary DAC, a lookup table to store a plurality of calibration code and a calibration logic coupled with the non-binary DAC. The self-calibrating DAC has two modes of operations, a calibration mode and a normal operational mode. In the calibration mode, the self-calibrating DAC is configured to calculate weightages of the non-binary DAC and to calculate an offset coefficient and a gain coefficients using high precision on chip analog-to-digital converter (ADC).
