The MAX5876 is an advanced 12-bit, 250Msps, dual
digital-to-analog converter (DAC). This DAC meets the
demanding performance requirements of signal synthesis
applications found in wireless base stations and other
communications applications. Operating from +3.3V and
+1.8V supplies, this dual DAC offers exceptional dynamic
performance such as 75dBc spurious-free dynamic range
(SFDR) at fOUT = 16MHz and supports update rates of
250Msps, with a power dissipation of only 287mW.
The MAX5876 utilizes a current-steering architecture
that supports a 2mA to 20mA full-scale output current
range, and allows a 0.1VP-P to 1VP-P differential output
voltage swing. The device features an integrated +1.2V
bandgap reference and control amplifier to ensure
high-accuracy and low-noise performance. A separate
reference input (REFIO) allows for the use of an external
reference source for optimum flexibility and
improved gain accuracy.
The clock inputs of the MAX5876 accept both LVDS
and LVPECL-compatible voltage levels. The device features
an interleaved data input that allows a single
LVDS bus to support both DACs. The MAX5876 is available
in a 68-pin QFN package with an exposed pad
(EP) and is specified for the extended temperature
range (-40°C to +85°C).
Refer to the MAX5877 and MAX5878 data sheets for pin-compatible 14-bit and 16-bit versions of the
MAX5876, respectively. Refer to the MAX5873 data
sheet for a CMOS-compatible version of the MAX5876.
