ADG408BRU-REEL

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG408BRU-REEL is a monolithic CMOS analog multiplexer featuring eight single channels. It operates with supply voltages up to ±15 V (dual) or 12 V (single), supporting signal ranges from VSS to VDD. Key electrical parameters include a maximum on-resistance of 100 Ω, off-isolation of -75 dB at 100 kHz, and channel-to-channel crosstalk of 85 dB. The device draws less than 75 μA supply current, exhibits a transition time of 250 ns max, and has a charge injection of 20 pC typ.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific package variant RU-16 corresponds to the Thin Shrink Small Outline Package configuration required for the design. Confirm that the REEL suffix indicates tape-and-reel packaging format rather than tube packaging. Ensure the B version temperature rating of -40°C to +85°C meets the operational environmental requirements. Cross-reference the ordering guide to confirm RoHS compliance status if indicated by a Z suffix in other variants.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an eight-channel single-ended multiplexer is required with low on-resistance and high off-isolation. The ADG408 is designed as a plug-in replacement for the DG408, offering improved performance characteristics such as lower power consumption and extended signal range. Consider the ADG409 if differential channel switching is needed instead of single-ended paths. Evaluate the break-before-make timing specifications against system glitch tolerance requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADG408/ADG409 family of high-performance analog multiplexers manufactured by Analog Devices Inc. These devices are built on an enhanced LC2MOS process to balance low power dissipation with high switching speed. The ADG408 specifically handles eight single-ended channels, while the companion ADG409 manages four differential channels. Both share similar pinouts and control logic for ease of integration into existing designs.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet explicitly identifies the ADG408 as a plug-in replacement for the DG408. Designers should verify that the legacy DG408's electrical limits, particularly regarding absolute maximum ratings and leakage currents, are compatible with the new component's specifications to ensure reliable operation without circuit modification.
