14-Bit, 260Msps High-Dynamic Performance DAC

The MAX5195 is an advanced, 14-bit, 260Msps digital-to-analog converter (DAC) designed to meet the demanding performance requirements of signal synthesis applications found in wireless base stations and other communication systems. Operating from a single 5V supply, this DAC offers exceptional dynamic performance such as 77dBc spurious-free dynamic range (SFDR) at fOUT = 19.4MHz, while supporting update rates beyond 260Msps.

The MAX5195 current-source array architecture supports a full-scale current range of 10mA to 20mA, which allows a differential output voltage swing between 0.5VP-P and 1VP-P.

The MAX5195 features an integrated 1.2V bandgap reference and control amplifier to ensure high accuracy and low-noise performance. Additionally, a separate reference input pin allows the user to apply an external reference source for optimum flexibility.

The digital and clock inputs of the MAX5195 are designed for differential LVPECL-compatible voltage levels.

The MAX5195 is available in a 48-lead QFN package with exposed paddle and is specified for the extended industrial temperature range (-40°C to +85°C).
