PRODUCT DESCRIPTION The AD9755 is a dual, muxed port, ultrahigh speed, singlechannel, 14-bit CMOS DAC. It integrates a high quality 14-bit TxDAC+ core, a voltage reference, and digital interface circuitry into a small 48-lead LQFP package. The AD9755 offers exceptional ac and dc performance while supporting update rates up to 300 MSPS.
The AD9755 has been optimized for ultrahigh speed applications up to 300 MSPS where data rates exceed those possible on a single data interface port DAC. The digital interface consists of two buffered...
