(17 pages)
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
(SFDR) at f
rates beyond 260Msps.
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
0.5V
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.
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).
