MAX5887

19-2777; Rev 1; 10/03 3.3V, 14-Bit, 500Msps High Dynamic Performance DAC with Differential LVDS Inputs General Description The MAX5887 is an advanced, 14-bit, 500Msps digitalto-analog converter (DAC) designed to meet the demanding performance requirements of signal synthesis applications found in wireless base stations and other communications applications. Operating from a single 3.3V supply, this DAC offers exceptional dynamic performance such as 76dBc spurious-free dynamic range (SFDR) at f OUT = 30MHz. The DAC supports update rates of 500Msps and a power dissipation of only 230mW. The MAX5887 utilizes a current-steering architecture, which supports a full-scale output current range of 2mA to 20mA, and allows a differential output voltage swing between 0.1VP-P and 1VP-P. The MAX5887 features an integrated 1.2V bandgap reference and control amplifier to ensure high accuracy and low noise performance. Additionally, a separate reference input pin enables the user to apply an external reference source for optimum flexibility and to improve gain accuracy. The digital and clock inputs of the MAX5887 are designed for differential low-voltage differential signal (LVDS)-compatible voltage levels. The MAX5887 is available in a 68-pin QFN package with an exposed paddle (EP) and is specified for the extended industrial temperature range (-40°C to +85°C). Refer to the MAX5886 and MAX5888 data sheets for pin-compatible 12- and 16-bit versions of the MAX5887. DGND DVDD B2N B3N B4N B2P B...
