This Paper presents a 10 bits 80 MSPS 2.5 V digital-to-analog converter (DAC) using 0.25 micrometer double poly four metal CMOS technology for mixed-signal applications. A segmented current steering architecture is used for this DAC. This architecture gives the most optimized results in terms of speed, resolution, area and power. The DAC can operate at a frequency of 80MHz and above. Total power dissipation is 27.6525 mW with 2.5 V power supply. It achieves differential nonlinearity and integral nonlinearity of ?0.55 LSB and ?0.4 LSB. It occupies an area of 0.185 mm².
