General Description
The MAX5886 is an advanced, 12-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
range (SFDR) at f
OUT
= 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 0.1V
P-P
and 1V
P-P
.
The MAX5886 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.
The digital and clock inputs of the MAX5886 are
designed for differential low-voltage differential signal
(LVDS)-compatible 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.
