MAX5875 19-3515 Rev 2 1/07 16-Bit, 200Msps, High-Dynamic-Performance, Dual DAC with CMOS Inputs General Description Features The MAX5875 is an advanced 16-bit, 200Msps, dual 200Msps Output Update Rate digital-to-analog converter (DAC). This DAC meets the Noise Spectral Density = -162dBFS/Hz at f = OUT demanding performance requirements of signal synthesis 16MHz applications found in wireless base stations and other Excellent SFDR and IMD Performance communications applications. Operating from 3.3V and SFDR = 78dBc at f = 16MHz (to Nyquist) 1.8V supplies, this dual DAC offers exceptional dynamic OUT SFDR = 75dBc at f = 80MHz (to Nyquist) performance such as 78dBc spurious-free dynamic range OUT (SFDR) at f = 16MHz and supports update rates of IMD = -86dBc at f = 10MHz OUT OUT IMD = -76dBc at f = 80MHz 200Msps, with a power dissipation of only 260mW. OUT The MAX5875 utilizes a current-steering architecture ACLR = 75dB at f = 61MHz OUT that supports a 2mA to 20mA full-scale output current 2mA to 20mA Full-Scale Output Current range, and allows a 0.1V to 1V differential output P-P P-P CMOS-Compatible Digital and Clock Inputs voltage swing. The device features an integrated 1.2V bandgap reference and control amplifier to ensure On-Chip 1.2V Bandgap Reference high-accuracy and low-noise performance. A separate Low 260mW Power Dissipation reference input (REFIO) allows for the use of an exter- Compact 68-Pin QFN-EP Package (10mm x 10mm) nal reference source for optimum flexibility and improved gain accuracy. Evaluation Kit Available (MAX5875EVKIT) The digital and clock inputs of the MAX5875 accept Ordering Information 3.3V CMOS voltage levels. The device features a flexi- ble input data bus that allows for dual-port input or a PIN- PKG PART TEMP RANGE single-interleaved data port. The MAX5875 is available PACKAGE CODE in a 68-pin QFN package with an exposed paddle (EP) MAX5875EGK-D -40C to +85C 68 QFN-EP* G6800-4 and is specified for the extended temperature range (-40C to +85C).
