Overview
The ADG408BN is a high-performance analog multiplexer produced by Analog Devices Inc. This monolithic CMOS device comprises eight single channels, allowing it to switch one of eight inputs to a common output. The switching is controlled by 3-bit binary address lines A0, A1, and A2, and an enable (EN) input is used to enable or disable the device. When disabled, all channels are switched off. The ADG408BN is fabricated on an enhanced LC2MOS process, which ensures low power dissipation, high switching speed, and low on-resistance.
