Vishay Siliconix DG201AP CMOS Quad SPST Analog Switch

Vishay Siliconix DG201AP CMOS Quad SPST Analog Switch is a four‑channel analog switch device that contains four independent single‑pole, single‑throw switches in one package, enabling straightforward routing of analog signals in a compact footprint. It is built on Vishay Siliconix’s CMOS process and, according to its packaging description, is housed in a purple ceramic package with gold-plated contacts. The DG201AP is designed for analog signal switching in instruments, telecommunications, and data‑acquisition circuits, providing four discrete SPST paths that can be opened or closed as needed. For exact electrical characteristics—such as supply voltage range, on‑resistance, leakage currents, and switching times—consult the official DG201 family datasheet to ensure accuracy for your design.
