applications found in wireless base stations and other at f OUT = 16MHz

communications applications. Operating from +3.3V and Excellent SFDR and IMD Performance +1.8V supplies, this dual DAC offers exceptional dynamic

performance such as 75d Bc spurious-free dynamic range

SFDR = 71d Bc at f OUT = 80MHz (to Nyquist)

(SFDR) at f OUT = 16MHz and supports update rates of

250Msps, with a power dissipation of only 287m W.

IMD = -73d Bc at f OUT = 80MHz

The MAX5876 utilizes a current-steering architecture
