General Description

The MAX5891 advanced 16-bit, 600Msps, digital-to-

analog converter (DAC) meets the demanding perfor-

mance requirements of signal synthesis applications

found in wireless base stations and other communica-

tions applications. Operating from +3.3V and +1.8V

supplies, the MAX5891 DAC supports update rates of

600Msps using high-speed LVDS inputs while consum-

ing only 298mW of power and offers exceptional

dynamic performance such as 80dBc spurious-free

The MAX5891 utilizes a current-steering architecture that

supports a 2mA to 20mA full-scale output current range,

and produces -2dBm to -22dBm full-scale output signal

levels with a double-terminated 50

Ω load. The MAX5891

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 MAX5891 digital inputs accept LVDS voltage lev-

els, and the flexible clock input can be driven differen-

tially or single-ended, AC- or DC-coupled. The

MAX5891 is available in a 68-pin QFN package with an

exposed paddle (EP) and is specified for the extended

(-40°C to +85°C) temperature range.

Refer to the MAX5890* and MAX5889* data sheets for

pin-compatible 14-bit and 12-bit versions of the

MAX5891.
