Overview
The ADG1613BRUZ-REEL, produced by Analog Devices Inc., is a quad single-pole/single-throw (SPST) analog switch integrated circuit. This device is part of the ADG1611/ADG1612/ADG1613 series, differing in their digital control logic. The ADG1613 has two switches with digital control logic similar to the ADG1611, while the other two switches have inverted logic. This configuration makes it suitable for various applications requiring precise control over analog signals.
The ADG1613 is designed with CMOS construction, ensuring ultralow power dissipation, which is ideal for portable and battery-powered instruments. It features break-before-make switching action, low charge injection, and an ultralow on-resistance profile, making it excellent for data acquisition, gain switching, and audio signal switching applications.
