MAX5886EGK+D

Digital To Analog Converters Overview

The MAX5886EGK+D is a 12-bit, 500Msps digital-to-analog converter (DAC) designed for high dynamic performance applications. It operates from a single 3.3V supply and features a current-steering architecture with a full-scale output current range of 2mA to 20mA. The device supports differential LVDS-compatible digital and clock inputs. Key electrical specifications include an SFDR of 76dBc at fOUT = 30MHz, an IMD of -85dBc at fOUT = 10MHz, and an ACLR of 70dB at fOUT = 61MHz. Power dissipation is typically 130mW, with a power-down mode reducing consumption to less than 1mW. It is housed in a 68-pin QFN-EP package and specified for temperatures between -40°C and +85°C.

Digital To Analog Converters Procurement Notes

Verify the component authenticity by checking the manufacturer marking against official documentation. Ensure the package matches the 68-pin QFN-EP specification. Confirm the temperature grade corresponds to the extended industrial range (-40°C to +85°C). Cross-reference the ordering suffix with the manufacturer's pinout and electrical parameter tables to ensure functional compatibility before integration into designs.

Digital To Analog Converters Selection Notes

Select this DAC when high-speed conversion at 500Msps is required alongside stringent dynamic performance metrics such as SFDR and IMD. Consider the 12-bit resolution and current-output architecture for applications requiring wide bandwidth and low noise. Evaluate the need for LVDS inputs for robust signal integrity in noisy environments. Compare power dissipation requirements against available thermal management solutions within the target system design constraints.

Digital To Analog Converters Part Context

The MAX5886 belongs to a family of high-performance DACs from Analog Devices/Maxim Integrated, including the MAX5887 and MAX5888. These devices share similar architectures but vary in resolution, offering 12-bit, 14-bit, and 16-bit options respectively. They are designed to meet the demanding requirements of wireless base stations and communication systems, providing pin-compatible alternatives for designers scaling performance needs.

Digital To Analog Converters Replacement Considerations

The MAX5887 and MAX5888 are pin-compatible 14-bit and 16-bit versions of the MAX5886. Verify that the increased resolution meets system requirements without exceeding interface or timing constraints. Check if the specific dynamic performance parameters at target frequencies align with application needs, as higher resolution variants may exhibit different noise characteristics.
