MAX5878EGK+TD

Digital To Analog Converters Overview

The MAX5878EGK+TD is a dual 16-bit digital-to-analog converter (DAC) with a 250Msps update rate. It operates from +3.3V and +1.8V supplies, dissipating 296mW at full speed. The device features a current-steering architecture supporting 2mA to 20mA full-scale output currents and differential voltage swings of 0.1V to 1V peak-to-peak. Key performance metrics include a spurious-free dynamic range (SFDR) of 76dBc at 16MHz output frequency and -164dBFS/Hz noise spectral density. It accepts LVDS-compatible clock and data inputs, includes an integrated +1.2V bandgap reference, and is housed in a 68-pin QFN package.

Digital To Analog Converters Procurement Notes

Verify the component status as discontinued before design finalization. Confirm the specific ordering suffix matches the required packaging and lead-free specifications. Ensure compatibility with existing board layouts due to the 68-QFN package dimensions. Review the datasheet for any obsolescence notices or recommended alternative part numbers from Analog Devices.

Digital To Analog Converters Selection Notes

Select this component for applications requiring high dynamic performance at 250Msps. Consider the MAX5876 or MAX5877 for pin-compatible 12-bit or 14-bit resolution options. Choose the MAX5875 if CMOS logic inputs are preferred over LVDS. Evaluate power dissipation requirements against the thermal capabilities of the 68-QFN package.

Digital To Analog Converters Part Context

The MAX5878 belongs to the Maxim Integrated high-performance DAC family. It shares pin compatibility with the MAX5876 (12-bit) and MAX5877 (14-bit). The MAX5875 offers a similar form factor but utilizes CMOS inputs instead of LVDS. This series targets demanding communications infrastructure applications requiring precise analog signal generation.

Digital To Analog Converters Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Pin-compatible alternatives within the same family include the MAX5876 and MAX5877, though they offer lower resolution.
