Overview
The ADG211AKN, produced by Analog Devices Inc., is a monolithic CMOS device that comprises four independently selectable single-pole, single-throw (SPST) switches. These switches are designed on an enhanced LC2MOS process, which enhances their signal handling capability to ±15 V. This makes them suitable for a wide range of analog signal switching applications. The ADG211A and ADG212A models differ primarily in their digital control logic, with the ADG211A having non-inverted logic and the ADG212A having inverted logic.
