MAX5878

The MAX5878 is an advanced 16-bit, 250Msps, dual digital-to-analog converter (DAC). This DAC meets the demanding performance requirements of signal synthesis applications found in wireless base stations and other communications applications. Operating from +3.3V and +1.8V supplies, this dual DAC offers exceptional dynamic performance such as 76dBc spurious-free dynamic range (SFDR) at f_OUT= 16MHz and supports update rates of 250Msps, with a power dissipation of only 296mW.The MAX5878 utilizes a current-steering architecture that supports a 2mA to 20mA full-scale output current range, and allows a 0.1V_P-Pto 1V_P-Pdifferential output voltage swing. The device features an integrated +1.2V bandgap reference and control amplifier to ensure high-accuracy and low-noise performance. A separate reference input (REFIO) allows for the use of an external reference source for optimum flexibility and improved gain accuracy.The clock inputs of the MAX5878 accept both LVDS and LVPECL-compatible voltage levels. The device features an interleaved data input that allows a single LVDS bus to support both DACs. The MAX5878 is available in a 68-pin QFN package with an exposed paddle (EP) and is specified for the extended temperature range (-40°C to +85°C).Refer to the MAX5876 and MAX5877 data sheets for pin-compatible 12-bit and 14-bit versions of the MAX5878, respectively. Refer to the MAX5875 datasheet for a CMOS-compatible version of the MAX5878.
