ADG408BRU

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG408BRU is a monolithic CMOS analog multiplexer featuring eight single channels. It operates with supply voltages ranging from ±5 V to ±15 V, providing an analog signal range extending to the rails. Key electrical parameters include a maximum on-resistance of 100 Ω and low power consumption with supply current under 75 μA. The device supports break-before-make switching and exhibits charge injection as low as 20 pC. It functions reliably within an industrial temperature range of −40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific package variant RU-16 (Thin Shrink Small Outline Package) matches design constraints. Confirm RoHS compliance status via the 'Z' suffix if required by environmental regulations. Ensure voltage ratings align with system supply limits. Check for updated revision history regarding pinout or thermal characteristics before finalizing procurement specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring high-speed analog switching with minimal power dissipation. The ADG408 offers a plug-in replacement for legacy DG408 devices. Consider the B version for industrial temperature ranges. Evaluate off-isolation and crosstalk specifications against signal integrity requirements in multi-channel environments.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADG408/ADG409 family of high-performance analog multiplexers manufactured by Analog Devices Inc. The ADG408 specifically handles eight single-ended channels, while the ADG409 manages four differential pairs. Both utilize enhanced LC2MOS technology to achieve low on-resistance and fast switching speeds suitable for precision data acquisition.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet identifies the ADG408 as a direct plug-in replacement for the DG408. Designers upgrading from older bipolar processes should verify that the CMOS input logic levels and supply voltage ranges are compatible with existing control circuitry.
