MAXIM MAX5889 Technical data

General Description
The MAX5889 advanced 12-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 MAX5889 DAC supports update rates of 600Msps using high-speed LVDS inputs while consum­ing only 292mW of power and offers exceptional dynamic performance such as 79dBc spurious-free dynamic range (SFDR) at f
OUT
= 30MHz.
The MAX5889 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 50load. The MAX5889 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 MAX5889 digital inputs accept LVDS voltage lev­els, and the flexible clock input can be driven differen­tially or single-ended, AC- or DC-coupled. The MAX5889 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 MAX5890 data sheets for pin­compatible 16-bit and 14-bit versions of the MAX5889.
