The MAX5885 is available in a 48-pin QFN package with an exposed 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. For LVDS high-speed versions, refer to the MAX5886/ MAX5887/MAX5888 data sheet. ♦ 200Msps Output Update Rate 48 The MAX5885 is an advanced, 16-bit, 200Msps digitalto-analog converter (DAC) designed to meet the demanding performance requirements of signal synthesis applications found in wireless base stations and other communications applications. Operating from a single 3.3V supply, this DAC offers exceptional dynamic performance such as 77dBc spurious-free dynamic range (SFDR) 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 0.1VP-P and 1VP-P. The MAX5885 features an integrated 1.2V bandgap reference and control amplifier to ensure high accuracy and low noise performance. Additionally, a separate reference input pin enables the user to apply an external reference source for optimum flexibility and to improve gain accuracy.
