The MAX326 and MAX327 are quad, single‑pole‑single‑throw (SPST) CMOS analog switches offering ultra‑low leakage (10 pA max) and low charge injection (2 pC typ). They operate from a wide range of supply configurations, including single (+10 V to +30 V), dual (+5 V to +18 V) and unbalanced supplies, making them suitable for high‑accuracy data acquisition, sample‑and‑hold circuits, communication and control systems.
The document provides electrical characteristics, absolute maximum ratings, dynamic performance data, ordering information, pin‑out diagrams and package dimensions. Application hints describe how to use the devices as low‑leakage upgrades for DG201A/DG202 and DG211/DG212, and include protection recommendations for over‑voltage and fault conditions.
