Overview
The ADG5208BRUZ, produced by Analog Devices Inc., is a monolithic CMOS analog multiplexer. This device features eight single channels, allowing it to switch one of eight inputs to a common output based on the 3-bit binary address lines A0, A1, and A2. An enable input (EN) allows the device to be enabled or disabled, with all channels switching off when EN is disabled. The ADG5208 is designed for applications requiring low glitch and fast settling times, making it ideal for data acquisition, sample-and-hold, and video signal switching.
