Dual DAC with LVDS Inputs

General Description Features

The MAX5878 is an advanced 16-bit, 250Msps, dual 250Msps Output Update Rate digital-to-analog converter (DAC). This DAC meets the

Noise Spectral Density = -164d BFS/Hz

demanding performance requirements of signal synthesis

at f OUT = 16MHz

applications found in wireless base stations and other

Excellent SFDR and IMD Performance

communications applications. Operating from +3.3V and

+1.8V supplies, this dual DAC offers exceptional dynamic SFDR = 76d Bc at f OUT = 16MHz (to Nyquist) performance such as 76d Bc spurious-free dynamic range SFDR = 71d Bc at f OUT = 80MHz (to Nyquist) (SFDR) at f OUT = 16MHz and supports update rates of IMD = -90d Bc at f OUT = 10MHz

250Msps, with a power dissipation of only 296m W. IMD = -72d Bc at f OUT = 80MHz

The MAX5878 utilizes a current-steering architecture ACLR = 75d B at f OUT = 61MHz
