Overview
The ADG408BRZ-REEL7 is a monolithic CMOS analog multiplexer produced by Analog Devices Inc. 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 ADG408BRZ-REEL7 is fabricated on an enhanced LC2MOS process, which ensures low power dissipation, high switching speed, and low on-resistance.
