The MAX5876 is a high-performance 12-bit, 250Msps, dual-channel digital-to-analog converter (DAC) that meets the demanding performance requirements of signal synthesis applications found in wireless base stations and other communications applications.
The MAX5876 is an advanced 12‑bit, 250 Msps dual digital‑to‑analog converter designed for high‑dynamic‑performance signal synthesis. It operates from +3.3 V and +1.8 V supplies, provides a full‑scale output current of 2 mA to 20 mA, and includes an on‑chip +1.2 V bandgap reference. The device supports LVDS‑compatible digital and clock inputs and is available in a 68‑pin QFN‑EP package for compact board integration.
Key specifications include 75 dBc spurious‑free dynamic range at 16 MHz, noise spectral density of –154 dBFS/Hz, and a power dissipation of only 287 mW. The datasheet details absolute maximum ratings, electrical characteristics, pin descriptions, and typical operating curves for SFDR, IMD, and power consumption across update rates.
