The MX7225 and MX7226 each contain four 8‑bit voltage‑output digital‑to‑analog converters with internal buffer amplifiers and input logic compatible with TTL/CMOS microprocessors. The MX7225 provides double‑buffered inputs and separate reference inputs for each DAC, while the MX7226 uses a single shared reference.
The document lists absolute maximum ratings, dual‑ and single‑supply electrical characteristics, timing diagrams, recommended PCB layouts, and interface examples for various microprocessors. It also covers grounding recommendations, unipolar and bipolar output configurations, and typical performance figures such as slew rate, settling time, and output sink current.
