General Description
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 exter-
nal 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 fea-
tures an interleaved data input that allows a single
LVDS bus to support both DACs. The MAX5876 is avail-
able 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.
