The MAX5891 advanced 16-bit, 600Msps, digital-toanalog
converter (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,
the MAX5891 DAC supports update rates of
600Msps using high-speed LVDS inputs while consuming
only 298mW of power and offers exceptional
dynamic performance such as 80dBc spurious-free
dynamic range (SFDR) at fOUT = 30MHz.
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 50Ω 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 levels,
and the flexible clock input can be driven differentially
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 pincompatible
14-bit and 12-bit versions of the MAX5891.
