ADG1408YRUZ 概述
An analog multiplexer is an analog switch network that connects one selected source channel to a shared destination. In the ADG1408, eight single-ended inputs are multiplexed onto one output. The address inputs control the selected path, while the common output provides a compact way to route signals in test equipment, data-acquisition systems, relay-replacement circuits, and audio/video equipment. This places the device in the interface IC hierarchy: analog switch → multiplexer → signal-routing IC.
Key features include a maximum on-resistance of 4.7 ohms, on-resistance flatness of 0.5 ohm, rail-to-rail operation, and break-before-make switching. The manufacturer lists operation across ±15 V, +12 V, and ±5 V supplies, plus compatibility with 3 V logic inputs. These features make the ADG1408 suitable for systems that require controlled switching of bipolar or low-voltage signals while maintaining defined break-before-make behavior.
The ADG1408YRUZ is specified in a 16-lead TSSOP package. Its 4.7-ohm maximum on resistance and 190-mA continuous-current capability provide useful performance for precision signal routing, although insertion loss and settling behavior depend on the source impedance, load, signal frequency, supply voltage, and layout. The 0.5-ohm on-resistance flatness helps minimize resistance variation across the selected switch network.
Typical applications include relay replacement, audio and video routing, automatic test equipment, data-acquisition systems, and signal-path multiplexing. The break-before-make action is particularly useful where briefly connecting two externally driven sources is undesirable. For high-speed or high-impedance systems, engineers should evaluate switch capacitance, off leakage, charge injection, and clock timing in the complete signal path.
The principal design consideration is ensuring that address transitions do not create an undesirable transient at the common output. Use the manufacturer-recommended supply bypassing, keep routing short, and account for the TSSOP footprint and pin orientation. This page combines the verified manufacturer and distributor information with engineering-oriented application guidance and sourcing details.

典型应用
ADG1408YRUZ 适用于 6 应用s: Relay-Replacement Signal Routing, Audio and Video Routing, Automatic Test Equipment, Data-Acquisition Systems, Industrial Control and Monitoring, Communication and RF-Signal Conditioning.
Relay-Replacement Signal Routing
The ADG1408YRUZ suits solid-state routing where a mechanical relay would be slow, wear-prone, or undesirable. Eight single-ended inputs can be selected onto one common output through the A0, A1, and A2 address lines. Its maximum on resistance of 4.7 ohm at 25°C and 190-mA continuous-current capability make it appropriate for moderate-amplitude, moderate-current signal paths. Break-before-make operation helps avoid momentarily connecting two externally driven sources. Designers should still check leakage, input voltage limits, and load capacitance against the application.
推荐
Audio and Video Routing
The ADG1408YRUZ can route one of eight single-ended audio or video sources to a common output for source selection and test-point routing. Its 4.7-ohm maximum on resistance is low enough for many general-purpose routing tasks, while the 0.5-ohm flatness helps limit channel-to-channel resistance variation. Rail-to-rail operation supports signal paths near the supply limits. The design must account for switch capacitance, off-state behavior, signal bandwidth, grounding, and the bandwidth of the downstream amplifier or receiver.
推荐
Automatic Test Equipment
The ADG1408YRUZ is useful in automatic test equipment for connecting one of eight test signals to a shared measurement or instrumentation path. Three binary address inputs allow digital control from a tester, controller, or communications interface. The 4.7-ohm maximum on resistance and 190-mA continuous-current rating support many general instrumentation signals, while break-before-make switching helps isolate channels during changes. For high-accuracy measurements, include switch resistance in the error budget and verify leakage, settling, and channel isolation for the selected operating conditions.
推荐
Data-Acquisition Systems
The ADG1408YRUZ can select among eight single-ended sensor or conditioned-signal inputs in a data-acquisition front end. The common output simplifies routing into a downstream converter, amplifier, or digitizer, while the 3 V-compatible address inputs support modern digital control. Its 4.7-ohm maximum on resistance should be included in the source-loading analysis, particularly with high-impedance sensors. The break-before-make characteristic is useful when switching between channels whose outputs are not guaranteed to be at the same potential.
推荐
Industrial Control and Monitoring
The ADG1408YRUZ can route multiple analog control or monitoring points into a common processing channel in industrial systems. The listed operating supplies of ±15 V, +12 V, and ±5 V support common industrial signal environments, while the address interface allows deterministic channel selection. The 4.7-ohm maximum on resistance and 190-mA continuous-current capability are useful for moderate-load instrumentation. Designers should verify the full signal range, transient protection, grounding, and fault-current behavior because those requirements are application-specific and are not established by the verified product snippets.
推荐
Communication and RF-Signal Conditioning
The ADG1408YRUZ can be used for controlled analog routing in communication equipment when eight single-ended paths must be selected onto one common line. Its 3 V-compatible address inputs simplify connection to digital control logic, and the family’s rail-to-rail operation can support low-voltage signal ranges. The 4.7-ohm on resistance may be acceptable for baseband or instrumentation paths, but high-frequency designs must verify capacitance, off isolation, insertion loss, and switching transients. It is not automatically suitable as a substitute for a dedicated RF switch.

关键差异点
- Eight-channel single-ended multiplexing （对比 ADG1409YRUZ)
- Defined break-before-make routing （对比 ADG1408)
- Low-resistance signal routing （对比 ADG1408-REEL7)
设计说明
Include the 4.7-ohm maximum on resistance in the insertion-loss budget for the selected channel. Estimated: for a 50-ohm system, a 4.7-ohm series resistance alone produces an approximate voltage-divider ratio of 50/(50+4.7) = 0.914, or about 0.78 dB loss before accounting for switch capacitance and other parasitics. Confirm the actual source and load impedance, frequency, and datasheet operating conditions.
Place the common output and selected input routing close to the device and keep the address traces away from sensitive analog paths. Provide local supply bypassing according to the manufacturer’s recommended layout practice. Because the device uses break-before-make switching, verify that address transitions do not create an unacceptable transient at the common output, especially when two external sources can be active simultaneously.
Do not treat ADG1408 and ADG1409 as interchangeable solely because both belong to the ADG1408/ADG1409 family. The ADG1408 is the eight-single-channel architecture, while the ADG1409 is the four-differential-channel architecture. Confirm the exact pinout, address logic, supply arrangement, and signal-channel definition from the manufacturer datasheet before substituting any part.
