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 f

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 0.1V

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.
