The 10-bit dual high-speed DAC is based on current steering architecture, which provides high-speed conversion rate and good dynamic performance. DAC consists of four principal blocks: adjustable bias, control logic, current source array and current output switches. Device has a feature of adjusting output current, output cascade transistors bias voltage, and entering sleep mode, turning device off. DAC requires 1 V digital supply, 1.8 V digital and analog supply, and digital and analog ground to work properly. Pins dac_adj[4:0] adjust DAC output current and pins vbias_cm0_adj[2:0] adjust output cascades transistors bias voltage.
