Analog Devices introduces a 14-bit digital-to-analog converter (DAC) that clocks at a sample rate of 1.2 GSPS. The fast data rates are made possible by the integration of LVDS digital interface technology. The AD9736 operates from 1.8 V and 3.3 V supplies, consuming 380 mW at 1.2 GSPS with the interpolation filter bypassed, and 550 mW with the interpolation filter enabled. The device features a 2X digital interpolation filter. The output currents can be programmed over a range of 10 mA to 30 mA, and can be configured for various single-ended or differential circuit topologies. The device's IMD is 74 dBc at an output frequency of 255 MHz and better than 65 dBc up to a 600 MHz output frequency. SFDR is 63 dBc at a 300 MHz output frequency and 53 dBc at 600 MHz, sampling at 1.2 GSPS. Noise spectral density of 158 dBm/Hz synthesizing a 300 MHz output.
