Overview
The ADG408BRUZ is a high-performance analog multiplexer produced by Analog Devices Inc. This device is part of the ADG408 series, which is designed on an enhanced LC²MOS process. This technology ensures low power dissipation while providing high switching speed and low on-resistance. The ADG408BRUZ switches one of eight inputs to a common output, controlled by 3-bit binary address lines A0, A1, and A2, and an enable input (EN) to activate or deactivate the device. Each channel conducts equally well in both directions when on and blocks signal levels up to the supply voltage when off, preventing momentary shorting due to break-before-make switching action.
