Overview
The ADG1608BRUZ, produced by Analog Devices Inc., is a monolithic CMOS analog multiplexer that switches one of eight inputs to a common output. This device is part of the ADG1608/ADG1609 family, which includes both single-channel and differential-channel configurations. The ADG1608 is specifically designed to handle eight single channels, controlled by 3-bit binary address lines (A0, A1, and A2). An enable input (EN) allows for the device to be enabled or disabled, with all channels switched off when disabled.
