The MAX5875 is a high‑performance 16‑bit dual digital‑to‑analog converter designed for signal‑synthesis applications such as wireless base stations and broadband wireless access. It operates from 3.3 V and 1.8 V supplies, offers a 200 Msps update rate, and provides a differential output swing of 0.1 V‑1 V P‑P.
Key features include a current‑steering architecture with 2 mA‑20 mA full‑scale output current, an on‑chip 1.2 V bandgap reference, low power dissipation (260 mW), and a compact 68‑pin QFN‑EP package. The device supports CMOS‑compatible digital and clock inputs and is specified for –40 °C to +85 °C operation.
