AD9755 is a dual, muxed port, ultrahigh speed, single- channel, 14-bit CMOS DAC.
The AD9755 is a dual‑port, 14‑bit CMOS DAC designed for ultrahigh‑speed applications. It integrates a high‑quality TxDAC+ core, on‑chip 1.20 V reference, and digital interface circuitry in a 48‑lead LQFP package. The device supports a maximum output update rate of 300 MSPS and provides differential current outputs ranging from 2 mA to 20 mA.
The converter operates from a single 3.0 V to 3.6 V supply, consuming only 155 mW at typical conditions. It offers excellent spurious‑free dynamic range and low distortion, making it suitable for communications, digital synthesis, and high‑speed data conversion tasks.
