The MAX5890 is a 14-bit, 600Msps, high-performance digital-to-analog converter (DAC) that meets the demanding performance requirements of signal synthesis applications found in wireless base stations and other communications applications
The MAX5890 is a high‑performance 14‑bit current‑steering DAC designed for signal‑synthesis applications such as wireless base stations and test equipment. It operates from 3.3 V or 1.8 V supplies and supports update rates up to 600 Msps while drawing only 297 mW.
Key features include a full‑scale output current range of 2 mA‑20 mA, spurious‑free dynamic range of 80 dBc at 30 MHz, low noise spectral density of –162 dBFS/Hz at 36 MHz, and an integrated 1.2 V bandgap reference. The device is offered in a 68‑pin QFN‑EP package and includes flexible LVDS data and clock inputs.
