Overview
The ADG512BRZ-REEL, produced by Analog Devices Inc., is a monolithic CMOS IC containing four independently selectable analog switches. These switches are part of the ADG511, ADG512, and ADG513 series, which are designed for precision analog signal switching. The ADG512BRZ-REEL operates with low, well-controlled on resistance and a wide analog signal range, making it ideal for various precision analog signal processing and data acquisition systems. The device is available in a 16-lead SOIC package and is suitable for single +3 V, +5 V, or ±5 V bipolar supply operations.
