MAX5874 19-3514 Rev 2 1/07 14-Bit, 200Msps, High-Dynamic-Performance, Dual DAC with CMOS Inputs General Description Features The MAX5874 is an advanced 14-bit, 200Msps, dual 200Msps Output Update Rate digital-to-analog converter (DAC). This DAC meets the Noise Spectral Density = -160dBFS/Hz at demanding performance requirements of signal synthesis applications found in wireless base stations and other f = 16MHz OUT communications applications. Operating from 3.3V and Excellent SFDR and IMD Performance 1.8V supplies, this dual DAC offers exceptional dynamic SFDR = 78dBc at f = 16MHz (to Nyquist) performance such as 78dBc spurious-free dynamic range OUT (SFDR) at f = 16MHz and supports update rates of SFDR = 74dBc at f = 80MHz (to Nyquist) OUT OUT 200Msps, with a power dissipation of only 260mW. IMD = -86dBc at f = 10MHz OUT IMD = -74dBc at f = 80MHz The MAX5874 utilizes a current-steering architecture OUT that supports a 2mA to 20mA full-scale output current ACLR = 75dB at f = 61MHz OUT range, and allows a 0.1V to 1V differential P-P P-P output voltage swing. The device features an integrated 2mA to 20mA Full-Scale Output Current 1.2V bandgap reference and control amplifier to ensure CMOS-Compatible Digital and Clock Inputs high-accuracy and low-noise performance. A separate reference input (REFIO) allows for the use of an exter- On-Chip 1.2V Bandgap Reference nal reference source for optimum flexibility and Low 260mW Power Dissipation improved gain accuracy. The digital and clock inputs of the MAX5874 accept 68-Lead QFN-EP Package 3.3V CMOS voltage levels. The device features a flexi- Evaluation Kit Available (MAX5874EVKIT) ble input data bus that allows for dual-port input or a single-interleaved data port. The MAX5874 is available Ordering Information in a 68-pin QFN package with an exposed paddle (EP) and is specified for the extended temperature range PIN- PKG PART TEMP RANGE (-40C to +85C).
