The MAX4747-MAX4750 low-voltage quad single-pole single-throw (SPST)/dual single-pole/double-throw (SPDT) analog switches operate from a single +2V to +11V supply and handle rail-to-rail analog signals. These switches exhibit low leakage current (0.1nA) and consume less than 0.5nW (typ) of quiescent power, making them ideal for battery-powered applications.
The MAX4747–MAX4750 family provides low‑voltage analog switching with four normally‑open (NO) or normally‑closed (NC) configurations, and two SPDT options. They operate from a single +2 V to +11 V supply, handle rail‑to‑rail signals, and feature low leakage (0.1 nA) and ultra‑low quiescent power (<0.5 nW), making them suitable for battery‑powered applications.
Available in 14‑pin TSSOP, 16‑pin TQFN, and 16‑bump WLP packages, the devices offer on‑resistance of 50 Ω max at +3 V (25 Ω max at +5 V) with tight channel matching. The datasheet includes detailed electrical characteristics, pin‑out tables, package drawings, and application notes for protection and layout.
