ADG1211/ADG1212/ADG1213 are low capacitance, low charge injection, ±15 V/+12 V iCMOS™ quad single-pole single-throw switches. The 1 pF switch off capacitance and 2.6 pF switch on capacitance make them ideal for applications demanding extremely low capacitance such as automatic test equipment, data acquisition systems, and portable systems.
The ADG1211, ADG1212, and ADG1213 are iCMOS quad SPST switches offering ultra‑low off‑capacitance (≈0.9 pF) and charge injection (<1 pC). They operate from a dual supply of ±15 V or a single supply of +12 V and feature 3 V logic‑compatible inputs without a separate logic supply.
The document provides detailed specifications, pin configurations for TSSOP and LFCSP packages, ordering information, and functional block diagrams. It is intended for designers of data‑acquisition, sample‑and‑hold, audio/video routing, and battery‑powered systems.
