MAX5873 19-3446 Rev 3 1/07 12-Bit, 200Msps, High-Dynamic-Performance, Dual DAC with CMOS Inputs General Description Features The MAX5873 is an advanced 12-bit, 200Msps, dual 200Msps Output Update Rate digital-to-analog converter (DAC). This DAC meets the Noise Spectral Density = -152dBFS/Hz demanding performance requirements of signal synthesis at f = 16MHz OUT 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) OUT 1.8V supplies, this dual DAC offers exceptional dynamic SFDR = 73dBc at f = 80MHz (to Nyquist) OUT performance such as 78dBc spurious-free dynamic range IMD = -85dBc at f = 10MHz OUT (SFDR) at f = 16MHz and supports update rates of OUT IMD = -74dBc at f = 80MHz OUT 200Msps, with a power dissipation of only 255mW. ACLR = 74dB at f = 61MHz OUT The MAX5873 utilizes a current-steering architecture 2mA to 20mA Full-Scale Output Current that supports a 2mA to 20mA full-scale output current CMOS-Compatible Digital and Clock Inputs range, and allows a 0.1V to 1V differential output P-P P-P voltage swing. The MAX5873 features an integrated On-Chip 1.2V Bandgap Reference 1.2V bandgap reference and control amplifier to ensure Low 255mW Power Dissipation high-accuracy and low-noise performance. A separate 68-Lead QFN-EP Package reference input (REFIO) allows for the use of an exter- Evaluation Kit Available (MAX5873EVKIT) nal reference source for optimum flexibility and improved gain accuracy. Ordering Information The digital and clock inputs of the MAX5873 accept PIN- PKG 3.3V CMOS voltage levels. The MAX5873 features a PART TEMP RANGE PACKAGE CODE flexible input data bus that allows for dual-port input or a single-interleaved data port.
