Overview
The MAX5890EGK, produced by Analog Devices Inc./Maxim Integrated, is a high-performance 14-bit digital-to-analog converter (DAC) designed to meet the demanding requirements of signal synthesis applications. This DAC operates at update rates of up to 600Msps and is particularly suited for use in wireless base stations and other communications systems. It features a current-steering architecture, high-speed LVDS inputs, and exceptional dynamic performance, including an 80dBc spurious-free dynamic range (SFDR) at an output frequency of 30MHz.
