Overview
The ADG1308BRUZ is a monolithic analog multiplexer produced by Analog Devices Inc. This device is part of the ADG1308 series, which includes 8-channel single-ended multiplexers. The ADG1308 switches one of eight inputs to a common output, controlled by 3-bit binary address lines A0, A1, and A2. An additional enable (EN) input allows the device to be enabled or disabled, with all channels switched off when disabled. The ADG1308 is designed for high performance, featuring low on-state resistance, break-before-make switching action, and low charge injection, making it suitable for various applications including audio and video routing, test equipment, and battery-powered systems.
