Overview
The ADG408BNZ 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. The switching is controlled by 3-bit binary address lines A0, A1, and A2. An additional enable (EN) input allows the device to be enabled or disabled, with all channels switched off when disabled.
The ADG408BNZ is fabricated on an enhanced LC2MOS process, which offers low power dissipation, high switching speed, and low on-resistance. Each channel conducts equally well in both directions when on and has an input signal range that extends to the supply rails. The device also features break-before-make switching action to prevent momentary shorting when switching channels and low charge injection for minimal transients when switching digital inputs.
