Overview
The ADG408BRZ-REEL, produced by Analog Devices Inc., is a monolithic CMOS analog multiplexer. This device comprises eight single channels and is designed to switch one of eight inputs to a common output based on the 3-bit binary address lines A0, A1, and A2. An additional EN input allows for enabling or disabling the device, with all channels switched off when disabled. The ADG408 is fabricated on an enhanced LC2MOS process, which ensures low power dissipation, high switching speed, and low on-resistance.
