Overview
The ADG408BRU-REEL7 is a monolithic CMOS analog multiplexer produced by Analog Devices Inc. This device is part of the ADG408 series, which comprises 8 single channels 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 EN input allows for enabling or disabling the device, with all channels switched off when disabled.
The ADG408 is built on an enhanced LC2MOS process, ensuring low power dissipation, high switching speed, and low on-resistance. Each channel conducts equally well in both directions when on and can handle input signal ranges that extend to the supplies. The design also includes break-before-make switching to prevent momentary shorting when switching channels and features low charge injection for minimal transients when switching digital inputs.
