The MAX5890 advanced 14-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 sup-

plies, the MAX5890 DAC supports update rates of

600Msps using high-speed LVDS inputs while consum-

ing only 297mW of power and offers exceptional

dynamic performance such as 80dBc spurious-free

dynamic range (SFDR) at f

The MAX5890 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 50Ω load. The MAX5890

features an integrated 1.2V bandgap reference and con-

trol amplifier to ensure high-accuracy and low-noise per-

formance. A separate reference input (REFIO) allows for

the use of an external reference source for optimum flexi-

bility and improved gain accuracy.

The MAX5890 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

MAX5890 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 MAX5891 and MAX5889 data sheets for

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

MAX5890.
