3.3V, 16-Bit, 500Msps High Dynamic
Performance DAC with Differential LVDS Inputs
General Description
Features
The MAX5888 is an advanced, 16-bit, 500Msps digital-
to-analog converter (DAC) designed to meet the
demanding performance requirements of signal synthe-
sis applications found in wireless base stations and
other communications applications. Operating from a
single 3.3V supply, this DAC offers exceptional dyna-
mic performance such as 76dBc spurious-free dynamic

The MAX5888 features an integrated 1.2V bandgap ref-
erence and control amplifier to ensure high accuracy
and low noise performance. Additionally, a separate
reference input pin enables the user to apply an exter-
nal reference source for optimum flexibility and to
improve gain accuracy.

TEMP RANGE
The digital and clock inputs of the MAX5888 are
designed for differential low-voltage differential signal
(LVDS)-compatible voltage levels. The MAX5888 is
available in a 68-lead QFN package with an exposed
paddle (EP) and is specified for the extended industrial
temperature range (-40°C to +85°C).
