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  
OUT  
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  
o Low Noise Performance  
0.5V  
and 1V  
.
P-P  
SNR = 160dB/Hz at f  
= 19.4MHz  
P-P  
OUT  
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).
