Overview
The ADG1612BRUZ-REEL, produced by Analog Devices Inc., is a quad single-pole/single-throw (SPST) analog switch. This component is part of the ADG1611/ADG1612/ADG1613 family, differing primarily in their digital control logic. The ADG1612 switches are turned on with a Logic 1 input, contrasting with the ADG1611 which uses Logic 0. This device is designed to offer low on-resistance, minimal charge injection, and low power dissipation, making it suitable for various applications including data acquisition, gain switching, and audio signal processing.
