MAX5887EGK+TD

Digital To Analog Converters Overview

The MAX5887EGK+TD is a 14-bit, 500Msps digital-to-analog converter (DAC) designed for high-performance signal synthesis. 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 inputs and includes an integrated 1.2V bandgap reference. Key dynamic specifications include a spurious-free dynamic range (SFDR) of 76dBc at fOUT = 30MHz and power dissipation of 130mW. It is housed in a 68-pin QFN-EP package and specified for the -40°C to +85°C temperature range.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and temperature rating. Ensure compatibility with LVDS signaling standards for data and clock interfaces. Confirm that the 68-pin QFN-EP thermal pad connection meets PCB layout requirements for adequate heat dissipation during operation.

Digital To Analog Converters Selection Notes

Select this component when high dynamic performance and low power consumption are required for wireless infrastructure applications. Consider the internal reference accuracy versus external reference flexibility based on system gain requirements. Evaluate the 50Ω double termination or transformer coupling options for optimal SFDR and ACLR performance in the target frequency range.

Digital To Analog Converters Part Context

The MAX5887 belongs to a family of high-speed DACs from Analog Devices/Maxim Integrated. Pin-compatible variants include the 12-bit MAX5886 and the 16-bit MAX5888, allowing for design scalability across different resolution requirements while maintaining consistent interface and packaging characteristics.

Digital To Analog Converters Replacement Considerations

Pin-compatible alternatives within the same series include the MAX5886EGK+TD (12-bit) and MAX5888AEGK+TD (16-bit). Verify that the resolution change aligns with system accuracy needs and that timing parameters remain sufficient for the application's clock speed.
