DG411DJ+ 概要
An analog switch is a semiconductor-controlled routing device that connects or disconnects an analog signal path under digital control. The DG411 belongs to the analog-switch hierarchy, where a CMOS switch IC combines low-voltage control logic with low-power, high-impedance off-state behavior. It is intended for precision test, measurement, audio, video, and industrial signal-routing systems where a compact four-channel device reduces component count.
The DG411 family provides improved matching among its four switches and guaranteed on-resistance flatness across the signal range. According to the Analog Devices DG411 product page and manufacturer datasheet, redesigned DG411 devices feature on-resistance matching of 3 ohm maximum and on-resistance flatness of 4 ohm maximum. These characteristics are useful when several channels must present similar resistance to precision measurement and signal-conditioning circuits.
The normally closed configuration routes each switched node to its corresponding common terminal while the control input is asserted. This differs from normally open SPST switches, which leave the signal path disconnected until enabled. DG411DJ+ combines four independent channels in one 16-pin PDIP package, allowing simultaneous routing of multiple sensor, audio, video, or test signals without using four separate switch packages.
Typical uses include audio and video signal routing, automated test equipment, sample-and-hold front ends, data acquisition systems, battery-powered instrumentation, and industrial measurement modules. The monolithic CMOS implementation provides high input impedance and low leakage, while the low on resistance helps reduce signal attenuation when a channel is closed.
The principal design consideration is signal voltage and logic compatibility. Verify the absolute maximum signal and supply limits in the manufacturer datasheet, do not exceed the 30 V supply-voltage ceiling, and ensure the control levels meet the device's TTL- or CMOS-compatible input thresholds. The 16-pin through-hole package also requires adequate lead spacing, insertion clearance, and protection from electrostatic discharge during handling.
This product page consolidates verified distributor availability, manufacturer information, comparison data, and practical application guidance for engineers evaluating the DG411DJ+ as a quad SPST routing device.

Automated Test Equipment Signal Routing
DG411DJ+ fits automated test systems that need to connect several instrument or DUT paths through a compact analog switch. Its four independent normally closed SPST channels can route test signals while a 45-ohm on resistance limits insertion loss in many low-frequency measurement systems. The manufacturer's specified 3-ohm maximum matching between switches and 4-ohm maximum on-resistance flatness are particularly useful when calibration depends on similar channel behavior. Because the channels are normally closed, software and fixture design must account for the connected default state. Confirm leakage, bandwidth, and maximum signal voltage against the datasheet before using the device near high-impedance meters.
おすすめ
Audio Signal Routing
The four-channel DG411DJ+ can route audio paths in mixer, amplifier, and test-fixture architectures. A 45-ohm on resistance is appropriate for many line-level audio systems because it provides a defined, repeatable insertion impedance without requiring a separate relay. The guaranteed 3-ohm maximum matching and 4-ohm maximum flatness help minimize channel-to-channel level variation when the same source is switched into several destinations. Since the switches are normally closed, signal-path isolation during reset differs from a normally open design. Engineers should evaluate distortion, off-state leakage, and switching transients against the complete analog gain stage rather than relying only on the DC on-resistance figure.
おすすめ
Video Signal Multiplexing
DG411DJ+ supports four-channel routing in cost-conscious video test and switching systems, particularly at lower frequencies where the 45-ohm on resistance is electrically acceptable. Matching among the four switches helps reduce channel-dependent gain errors, while flatness of 4 ohm maximum limits resistance variation over the signal range. The 16-pin PDIP package is useful for through-hole prototype and legacy instrument designs where a surface-mount package would complicate assembly. For video paths, however, engineers must verify bandwidth, capacitance, charge injection, and crosstalk rather than inferring performance from DC resistance. The normally closed topology may also be unsuitable where the output must remain isolated during power-up.
おすすめ
Data Acquisition Front End
DG411DJ+ can provide four independently selected normally closed paths in a multiplexed data-acquisition front end. The 45-ohm switch resistance is small relative to many low-frequency sensors and amplifier inputs, while the 3-ohm maximum switch-to-switch matching improves repeatability during calibration. A four-channel package reduces routing-component count compared with four individual SPDT or SPST devices. The design must account for switched-input charge injection and off-state leakage, especially with high-impedance sensors, because these effects are not characterized by the simple on-resistance figure. The 10 V to 30 V operating range supports legacy industrial instrumentation, and TTL-compatible control allows straightforward interfacing from older digital control hardware.
おすすめ
Battery-Powered Instrumentation
DG411DJ+ is appropriate for portable measurement equipment that uses four switchable sensor or reference paths. Its monolithic CMOS implementation provides low off-state leakage, an important property when the device continuously connects to the supply through normally closed contacts. The compact integration of four SPST channels reduces board area relative to four discrete packages, while the 16-pin PDIP format is straightforward to prototype and service. Designers should calculate leakage-driven error in high-impedance battery-powered circuits, verify the logic levels of the portable controller, and ensure the 10 V minimum supply requirement is compatible with the system rail. A boost or regulated auxiliary supply may be needed if the main battery voltage is lower.
おすすめ
Industrial Sensor Switching
DG411DJ+ can multiplex industrial sensors whose signals remain within the switch's 10 V to 30 V supply framework. Four independent channels allow a controller to select thermocouple, strain-gauge, or other conditioned sensor paths without changing the analog front end. The low on-resistance variation supports repeatable calibration, while the 16-lead PDIP package is practical for rugged through-hole instrument boards. Industrial use requires careful isolation planning: off-state leakage, common-mode range, switching transients, and fault energy can affect sensor accuracy or safety. The normally closed contacts need appropriate software defaults so an unexpected reset does not connect an unintended excitation or measurement source.

設計ノート
Do not treat the 45-ohm on resistance as the only switch-selection criterion. Check leakage, bandwidth, charge injection, off-state isolation, and allowable signal voltage in the manufacturer datasheet, especially for high-impedance sensors. Also confirm that the normally closed topology is acceptable: DG411DJ+ connects its switched terminals through the common terminals when the control state is inactive, so reset or power-up behavior can prevent the isolation expected by the system.
Keep routing between DG411DJ+ and the connected analog circuit short and use a ground plane that returns control and signal currents without crossing sensitive paths. The 3-ohm maximum on-resistance matching and 4-ohm maximum flatness improve channel consistency, but PCB capacitance and leakage can still dominate in high-impedance designs. Place input protection outside the switch when exposed signals can exceed the 10 V to 30 V supply framework, and evaluate crosstalk at the intended operating frequency.
Provide a stable supply within the verified 10 V to 30 V operating range and decouple it close to the device using the manufacturer-recommended network. The four normally closed channels can draw leakage current continuously when the off state is implemented by separating rather than opening the path, so power calculations should include worst-case channel states. Confirm TTL- or CMOS-compatible control levels with the actual controller supply voltage rather than assuming 5 V CMOS thresholds are sufficient in every configuration.
