3.3V, 12-Bit, 500Msps High Dynamic Performance DAC with Differential LVDS Inputs
General Description
The MAX5886 is an advanced, 12-bit, 500Msps digitalt o - a n a l o g 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 fOUT = 30MHz. The DAC supports update rates of 500Msps and a power dissipation of only 230mW. The MAX5886 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 MAX5886 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 extern a l reference source for optimum flexibility and to improve gain accuracy. The digital and clock inputs of the MAX5886 are designed for differential low-voltage differential signal ( L V D S ) - c o m p a t i b l e voltage levels. The MAX5886 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 MAX5887 and MAX5888 data sheets for pin-compatible 14- and 16-bit versions of the MAX5886.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
