DG401/DG403/DG405 is a high-performance switch with low on-resistance and low leakage current, suitable for sample-and-hold circuits, test equipment, guidance and control systems, heads-up displays, communication systems, PBX, PABX, battery-operated systems, audio signal routing, military radios, etc. applications.
The Maxim DG401/DG403/DG405 family are dual, high‑speed analog switches with low on‑resistance and low charge injection. The DG401 is a single‑pole/single‑throw device, the DG403 is dual‑pole/double‑throw, and the DG405 is dual‑pole/single‑throw. They operate from a single +10 V to +30 V supply or bipolar ±4.5 V to ±20 V supplies.
The datasheet provides absolute maximum ratings, electrical characteristics, pin configurations, timing diagrams, and ordering information. It also lists typical applications such as sample‑and‑hold circuits, test equipment, and communication systems.
