8-Bit, 125 MSPS Dual TxDAC+® D/A Converter

The AD9709 is a dual port, high-speed, two channel, 8-bit CMOS DAC It integrates two high-quality 8-bit TxDAC+ cores, a Voltage Reference and digital Interface circuitry into a small 48-lead LQFP package. The AD9709 offers exceptional ac and dc performance while supporting update rates up to 125 MSPS.
The AD9709 has been optimized for processing I and Q data in Communications applications. The digital Interface consists of two double-buffered Latches as well as control Logic Separate write inputs allow data to be written to the two DAC ports independent of one another. Separate Clocks control the update rate of the DACs
A mode control pin allows the AD9709 to Interface to two separate data ports, or to a single interleaved high-speed data port. In interleaving mode the input data stream is demuxed into its original I and Q data and then latched. The I and Q data is then converted by the two DACs and updated at half the input data rate.
The DACs utilize a segmented current source architecture combined with a proprietary switching technique to reduce glitch energy and to maximize dynamic accuracy. Each DAC provides differential current output thus supporting single-ended or differential applications. Both DACs CAN be simultaneously updated and provide a nominal full-scale current of 20 mA. The full-scale currents between each DAC are matched to within 0.5%. The AD9709 is manufactured on an advanced low cost CMOS process. It operates from a single supply of 3.0 Vto 5.5 V and consumes <400 mW of power.
