DG413CJ+ - 4-Channel SPST Analog Switch | Analog Devices
MPN： DG413CJ+ ✓ 啟用中DG413CJ+ 概覽
An analog switch is an integrated semiconductor device that connects or disconnects signal paths under digital control. The DG413 belongs to the analog-switch and multiplexer hierarchy, using MOSFET switch elements to control voltage or current paths. Unlike a mechanical relay, it provides compact, solid-state switching and is intended for low-voltage signal routing rather than power switching. Its four-channel architecture lets one system control multiple analog measurement or signal nodes efficiently.
The DG413 family is documented by Analog Devices as an improved quad SPST analog switch with low on-resistance matching between switches and guaranteed on-resistance flatness over the signal range. Verified manufacturer-family information states that the redesigned DG411, DG412, and DG413 switches provide on-resistance matching of 3 ohm maximum and on-resistance flatness variation of 4 ohm maximum. This helps reduce channel-to-channel error in instrumentation and test systems. The DG413CJ+ is specifically identified as the PDIP-16, through-hole ordering variant.
The device supports dual supplies from -20 V to -4.5 V and +4.5 V to +20 V, with a maximum dual supply span stated as ±20 V. Its four normally open SPST channels can be used to route external signals, sample-and-hold paths, or measurement inputs. The 145 ns maximum off time and 45 ohm maximum on-resistance are useful when timing and insertion resistance matter, although the verified data does not provide every timing threshold or control-pin detail.
Typical applications include automated test equipment, oscilloscope and instrument signal routing, data-acquisition systems, sensor interface switching, communication signal conditioning, and control systems requiring multiple analog paths. Designers should account for the relatively high 45 ohm maximum on-resistance compared with modern low-resistance switches, especially when driving high-impedance sensors or precision divider networks.
A key design consideration is the ±4.5 V minimum dual supply requirement. The through-hole PDIP-16 package is appropriate for through-hole assembly, prototyping, repair, and industrial control boards, but it is not interchangeable with surface-mount TSSOP-16 variants without a package redesign. This page combines verified manufacturer-family information, distributor observations, package details, and design guidance for DG413CJ+ selection and replacement planning.

典型應用
DG413CJ+ 適用於 7 應用s: Automated Test Equipment, Data-Acquisition Systems, Sensor Interface Switching, Instrument Signal Routing, Communication Signal Conditioning, Process-Control Signal Routing, Educational and Prototype Circuitry.
Automated Test Equipment
DG413CJ+ fits four-channel analog signal routing in automated test systems because it provides four normally open SPST paths in one PDIP-16 device. The verified maximum on-resistance is 45 ohm, so the inserted resistance must be included when sizing sense paths, dividers, or low-impedance sources. Its 145 ns maximum off time is useful when the test system changes measurement connections, while the through-hole package simplifies insertion into industrial test fixtures and repairable controller boards. Engineers should verify control levels, supply sequencing, and signal limits against the manufacturer datasheet before using the switch directly on high-current or high-voltage nodes.
推薦
Data-Acquisition Systems
DG413CJ+ can route sensor and reference signals in a multiplexed data-acquisition front end, where four independent channels reduce the number of discrete switches. Its four-channel architecture allows a controller to select different measurement paths without changing the analog wiring around the acquisition circuitry. The 45 ohm maximum on-resistance may be acceptable for high-impedance sensors, but it can introduce gain error or attenuation when the source impedance is low. Designers should calculate the complete divider formed by the switch, source, and input impedance, and verify that the selected architecture does not require a lower-resistance switch.
推薦
Sensor Interface Switching
DG413CJ+ is suitable for selecting among sensor outputs, test points, or amplifier inputs in a sensor interface when the signals remain within the switch's supply and signal limits. The four normally open SPST channels provide independent connection control, and the verified ±4.5 V minimum dual supply supports bipolar bias arrangements when the surrounding circuit requires them. Because the maximum on-resistance is 45 ohm, high-impedance sensors are generally more suitable than low-impedance sources. Layout should keep the switched path short and provide a defined return path to avoid coupling sensor noise into the selected measurement channel.
推薦
Instrument Signal Routing
DG413CJ+ can connect external instruments, calibration nodes, and internal reference paths in a compact measurement instrument. Four SPST channels allow a controller to isolate or select several analog points while keeping the package count lower than four separate single switches. The verified 145 ns maximum off time supports relatively fast routing decisions, but the complete switching timing and control behavior should be checked in the manufacturer datasheet. The PDIP-16 through-hole package is particularly useful for prototype instruments and repairable industrial electronics where through-hole assembly and socketed replacement are preferred.
推薦
Communication Signal Conditioning
DG413CJ+ may be used to route low-frequency analog control, feedback, or monitoring signals in communication equipment when the inserted resistance is acceptable. The four-channel normally open SPST structure can isolate branches and route them under control logic, while the ±20 V maximum dual supply provides compatibility with systems using bipolar rails. Designers must avoid using the switch for power switching unless the complete voltage, current, power, and transient limits are verified. Keep control traces away from sensitive analog paths and confirm that switch capacitance and timing meet the communication bandwidth requirements.
推薦
Process-Control Signal Routing
DG413CJ+ can select external control or monitor signals in a process-control system when the operating temperature remains within the verified 0 C to +70 C range. The four SPST channels are useful for isolating field inputs, selecting calibration references, or routing signals between controller stages. Its through-hole PDIP-16 package is straightforward to assemble and service on control boards, but the 45 ohm maximum on-resistance should be included in input-loading calculations. For installations outside the verified temperature range, select a suitably rated industrial switch rather than assuming typical-rated commercial parts are adequate.
推薦
Educational and Prototype Circuitry
DG413CJ+ is useful for teaching laboratories, breadboard prototypes, and repairable demonstration boards because it exposes four SPST switch channels in a standard PDIP-16 package. Students can use the part to demonstrate analog signal isolation, control routing, and the effect of on-resistance in simple measurement systems. The verified 45 ohm maximum resistance is easy to include in classroom calculations, while the 145 ns maximum off time provides a defined timing reference. For low-voltage educational signals, include supply bypassing and control-logic pull resistors exactly as specified in the manufacturer documentation.

主要差異化特點
- Four-channel analog routing in one package (對比DG413DJ)
- Through-hole package for repairable and prototype boards (對比DG413CUE+T)
- Documented family on-resistance matching and flatness (對比DG413CJ)
設計說明
The DG413CJ+ is a PDIP-16 through-hole device, so its PCB footprint must provide 16 through-hole pins with spacing matching the manufacturer package drawing. Do not substitute a TSSOP-16 footprint: the verified comparison explicitly identifies DG413CUE+T as TSSOP-16 and surface mount, which requires a different land pattern and assembly process.
Include the verified 45 ohm maximum on-resistance when calculating insertion loss, divider ratios, and sensor-source loading. The DG413 family documentation describes improved on-resistance matching and flatness, but matching specifications do not remove the resistance itself. For high-impedance sensors, the effect may be small; for low-impedance sources, a lower-resistance switch may be required.
Design the supply rails around the verified range of -4.5 V to +4.5 V minimum and -20 V to +20 V maximum. Confirm control-input levels, analog signal limits, and supply sequencing in the manufacturer datasheet before connecting bipolar signals. The available distributor data does not provide every absolute maximum or control threshold, so those values must not be inferred from the supply rating.
Do not treat a same-family suffix change as automatically approved without checking the complete datasheet. DG413DJ and DG413CJ share the PDIP-16 and four-channel SPST description in the verified cross-reference results, but exact control, voltage, timing, and lifecycle details remain incomplete there. Validate the full pin function and operating limits before substitution.
