16-Bit, 600Msps, High-Dynamic-Performance
DAC with LVDS Inputs
General Description
Features
♦ 600Msps Output Update Rate
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 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.
♦ 2mA to 20mA Full-Scale Output Current
♦ LVDS-Compatible Digital Inputs
♦ On-Chip +1.2V Bandgap Reference
♦ Low 298mW Power Dissipation at 600Msps
♦ Compact (10mm x 10mm) QFN-EP Package
♦ Evaluation Kit Available (MAX5891EVKIT)
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.
