Abstract
A digital-to-analog converter (DAC, 300) utilizes a coarse DAC (306) and fine DAC (315) to produce an analog output signal having both low glitch energy and good linearity performance. The DAC (300) also uses an error table (312) to store correction data generated through a calibration procedure. Outputs (307, 311) from each DAC (306, 315) are summed to produce an analog output signal which exhibits better linearity than does the output (307) of the coarse DAC (306) alone.
