General Description

The MAX5887 is an advanced, 14-bit, 500Msps digital-

to-analog converter (DAC) designed to meet the

demanding performance requirements of signal synthe-

sis applications found in wireless base stations and

other communications applications. Operating from a

single 3.3V supply, this DAC offers exceptional dyna-

mic performance such as 76dBc spurious-free dynamic

range (SFDR) at f

OUT

= 30MHz. The DAC supports

update rates of 500Msps and a power dissipation of

only 230mW.

The MAX5887 utilizes a current-steering architecture,

which supports a full-scale output current range of 2mA

to 20mA, and allows a differential output voltage swing

between 0.1V

P-P

and 1V

P-P

The MAX5887 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 enables the user to apply an exter-

nal reference source for optimum flexibility and to

improve gain accuracy.

The digital and clock inputs of the MAX5887 are

designed for differential low-voltage differential signal

(LVDS)-compatible voltage levels. The MAX5887 is

available in a 68-pin QFN package with an exposed

paddle (EP) and is specified for the extended industrial

temperature range (-40°C to +85°C).

Refer to the MAX5886 and MAX5888 data sheets for

pin-compatible 12- and 16-bit versions of the MAX5887.
