The Maxim MX7528 and MX7628 are CMOS dual 8‑bit buffered multiplying DACs that provide two independent digital‑to‑analog conversion channels. Each DAC features a thin‑film R‑2R resistor ladder, on‑chip latches for data storage, and separate reference inputs, allowing precise and matched analog output.
The document includes detailed electrical characteristics, switching timing, dynamic performance, package options, and ordering information. It is intended for designers integrating these DACs into programmable attenuators, motion‑control systems, digital‑to‑synchronization converters, and other applications requiring high‑resolution analog output.
