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
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.
