MAX5877 Series

The MAX5877 is an advanced 14-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 75dBc spurious-free dynamic range (SFDR) at fOUT= 16MHz and supports update rates of 250Msps, with a power dissipation of only 287mW.The MAX5877 utilizes a current-steering architecture that supports a 2mA to 20mA full-scale output current range, and allows a 0.1VP-Pto 1VP-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 MAX5877 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 MAX5877 is available in a 68-pin QFN package with an exposed pad (EP) and is specified for the extended temperature range (-40°C to +85°C).Refer to theMAX5876andMAX5878data sheets for pin-compatible 12-bit and 16-bit versions of the MAX5877, respectively. Refer to theMAX5874data sheet for a CMOS-compatible version of the MAX5877.See a parametric table of the complete family of pin-compatible 12-/14-/16-bit high-speed DACs.ApplicationsAutomated Test Equipment (ATE)Base Stations: Single-/Multicarrier UMTS, CDMA, GSMCable Modem Termination Systems (CMTS)Communications: Fixed Broadband Wireless Access, Point-to-Point MicrowaveDirect Digital Synthesis (DDS)Instrumentation
