Abstract
A digital-to-analog converter (DAC) and an operation method thereof are provided. The DAC includes a first operational amplifier (OPA), a second OPA, a resistor circuit, first switches, second switches, a first voltage shift circuit and a second voltage shift circuit. The first OPA outputs a first operating voltage. The second OPA outputs a second operating voltage. First terminals of the first switches receive the first operating voltage. First terminals of the second switches receive the second operating voltage. Second terminals of the first switches and the second switches are coupled to the resistor circuit. The first switches and the second switches perform switching operations in response to digital values. The first voltage shift circuit provides a first compensation voltage to the first OPA. The second voltage shift circuit provides a second compensation voltage to the second OPA.
