General Description
The MAX5885 is an advanced, 16-bit, 200Msps digital-to-analog converter (DAC) designed to meet the demanding performance requirements of signal synthe-sis applications found in wireless ba stations and other communications applications. Operating from a single 3.3V supply, this DAC offers exceptional dyna-mic performance such as 77dBc spurious-free dynamic range (SF DR) at f OUT = 10MHz. The DAC supports update rates of 200Msps at a power dissipation of less than 200mW.
The MAX5885 utilizes a current-steering architecture,which supports a full-scale output current range of 2mA to 20mA, and allows a differential output voltage swing between 0.1V P-P and 1V P-P .
The MAX5885 features an integrated 1.2V bandgap reference and control amplifier to ensure high accuracy and low noi performance. Additionally, a parate reference input pin enables the ur to apply an exter-nal reference source for optimum flexibility and to improve gain accuracy.
The digital and clock inputs of the MAX5885 are designed for CMOS-compatible voltage levels. The MAX5885 is available in a 48-pin QFN package with an expod paddle (EP) and is specified for the extended industrial temperature range (-40°C to +85°C).
Refer to the MAX5883 and MAX5884 data sheets for pin-compatible 12- and 14-bit versions of the MAX5885.F or LVDS high-speed versions, refer to the MAX5886/MAX5887/MAX5888 data sheet.
