14-Bit, 260Msps High-Dynamic
Performance DAC
General Description
Features
The MAX5195 is an advanced, 14-bit, 260Msps digital-
to-analog converter (DAC) designed to meet the
demanding performance requirements of signal synthe-
sis applications found in wireless base stations and
other communication systems. Operating from a single
5V supply, this DAC offers exceptional dynamic perfor-
mance such as 77dBc spurious-free dynamic range
o 260Msps Output Update Rate
o Excellent SFDR Performance
To Nyquist (-12dBFS)
At 19.4MHz Output = 77dBc
At 51.6MHz Output = 76dBc
o Industry-Leading IMD Performance
For 4 Tones (-15dBFS)
(SFDR) at f
= 19.4MHz, while supporting update

rates beyond 260Msps.
At 18MHz Output = 86dBc
At 31MHz Output = 84dBc
The MAX5195 current-source array architecture sup-
ports a full-scale current range of 10mA to 20mA, which
allows a differential output voltage swing between

The MAX5195 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 allows the user to apply an external
reference source for optimum flexibility.
o On-Chip 1.2V Bandgap Reference
o 20mA Full-Scale Current
o Single 5V Supply
o Differential LVPECL-Compatible Digital Inputs
o 48-Lead QFN-EP Package
The digital and clock inputs of the MAX5195 are
designed for differential LVPECL-compatible voltage
levels.
The MAX5195 is available in a 48-lead QFN package
with exposed paddle and is specified for the extended
industrial temperature range (-40°C to +85°C).
