Overview
The ADG1611BRUZ, produced by Analog Devices Inc., is a quad single-pole/single-throw (SPST) analog switch. This device is part of the ADG1611/ADG1612/ADG1613 family, differing primarily in their digital control logic. The ADG1611 switches are activated with a Logic 0 input, making it suitable for various applications requiring precise control over analog signals. The device is available in a 16-lead TSSOP package, ensuring compact integration into a wide range of electronic systems.
