ADG408BRUZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG408BRUZ is a monolithic CMOS analog multiplexer featuring eight single channels, switching one of eight inputs to a common output via 3-bit binary address lines. It operates on an enhanced LC2MOS process with a maximum supply rating of 44 V and supports both single (12 V) and dual (±15 V) supplies. Key electrical parameters include a maximum on-resistance of 100 Ω, a transition time of 130 ns, and charge injection of 5 pC under single-supply conditions. The device functions within an industrial temperature range of −40°C to +85°C and is housed in a 16-lead TSSOP package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Enhanced signal range extending to the supply rails due to LC2MOS fabrication.
• Low power dissipation with supply current below 75 μA.
• Break-before-make switching action prevents momentary shorting during channel transitions.
• Single-supply operation capability for unipolar analog signals.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the specific part number matches the required package type and RoHS compliance status. Confirm the operating temperature range aligns with system requirements. Ensure digital input voltage levels are compatible with the logic family used in the design. Check datasheet specifications for absolute maximum ratings to prevent device damage during installation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low on-resistance and fast switching speeds in a compact surface-mount package. Consider the 100 Ω maximum on-resistance and 130 ns transition time for signal integrity requirements. Evaluate the single-supply versus dual-supply configuration based on the analog signal range. Verify that the 16-lead TSSOP footprint fits the PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG408BRUZ belongs to the ADG408/ADG409 series of high-performance analog multiplexers manufactured by Analog Devices Inc. It serves as a plug-in replacement for legacy DG408/DG409 devices. The BRUZ suffix indicates a lead-free, RoHS-compliant version packaged in a 16-lead Thin Shrink Small Outline Package (TSSOP).

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG408BRZ is a verified equivalent offering identical functionality in a 16-lead SOIC package. Designers should verify pin compatibility and thermal characteristics when substituting between TSSOP and SOIC packages.
