The MAX5580–MAX5585 series are quad digital‑to‑analog converters offering 12‑, 10‑, or 8‑bit resolution with buffered voltage outputs. They operate from a +2.7 V to +5.25 V analog supply and a separate +1.8 V to +5.25 V digital supply, and support a 20 MHz, 3‑wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP protocols. The devices include two user‑programmable digital I/O ports and selectable output‑buffer configurations (unity‑gain or force‑sense).
The datasheet details absolute maximum ratings, electrical and timing characteristics, power‑supply recommendations, layout guidelines, and application examples such as unipolar and bipolar output configurations. It also provides typical performance graphs for integral and differential non‑linearity across the supported code ranges.
