The DAC3283 is a dual-channel 16-bit 800 MSPS digital-to-analog converter (DAC) with features such as an 8-bit input LVDS data bus, wideband communications, digital synthesis, and multi-DAC synchronization.
The DAC3283 is a dual‑channel 16‑bit DAC capable of 800 MSPS conversion rates. It features an 8‑bit LVDS input bus, selectable 2×‑4× interpolation filters, on‑chip 1.2 V reference, and a differential scalable output of 2‑20 mA. The device supports multi‑DAC synchronization, a coarse mixer for frequency up‑conversion, and digital I/Q correction.
The datasheet provides detailed electrical specifications, absolute maximum ratings, thermal characteristics, and package information for the 48‑pin 7 × 7 mm QFN (RGZ) package. It also includes pin‑out tables, functional block diagrams, and land‑pattern guidelines for PCB design.
