The MAX5874 is an advanced 14-bit, 200Msps, 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 78dBc spurious-free dynamic range
(SFDR) at fOUT = 16MHz and supports update rates of
200Msps, with a power dissipation of only 260mW.
The MAX5874 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 digital and clock inputs of the MAX5874 accept
3.3V CMOS voltage levels. The device features a flexible
input data bus that allows for dual-port input or a
single-interleaved data port. The MAX5874 is available
in a 68-pin QFN package with an exposed paddle (EP)
and is specified for the extended temperature range
(-40°C to +85°C).
Refer to the MAX5873 and MAX5875 data sheets for
pin-compatible 12-bit and 16-bit versions of the
MAX5874, respectively. Refer to the MAX5877 for an
LVDS-compatible version of the MAX5874.
