DG407DN+

DG407DN+ - Dual 8:1 CMOS Analog Multiplexer | Analog Devices

The Analog Devices DG407DN+ is an improved dual 8-channel CMOS analog multiplexer with a maximum on-state resistance of 100 ohm, packaged in a 28-pin PLCC. It combines two independently addressed 8:1 muxes with TTL- and CMOS-compatible channel-selection logic, allowing sixteen analog inputs to share two common outputs. The device supports communication systems, audio signal routing, data acquisition, guidance and control systems, sample-and-hold circuits, and test equipment. An analog multiplexer is a semiconductor switching network that routes one of several analog inputs to a shared output according to binary address and enable signals. In the signal-chain hierarchy, the DG407DN+ is a CMOS analog switch IC, a precision signal-routing component, and part of a broader data-acquisition or communication system. The 28-pin PLCC provides a standardized leaded surface-mount footprint suitable for compact industrial, instrumentation, and embedded-control equipment. The manufacturer describes DG407 as an improved 16-channel or dual 8-channel CMOS analog multiplexer family. Verified distributor information identifies DG407DN+ as a two-circuit 8:1 switch with 100-ohm maximum on-state resistance in a 28-pin PLCC measuring 11.51 mm by 11.51 mm. Its TTL- and CMOS-compatible digital decode circuitry allows the address and enable inputs to operate with common logic families, while the enable function can deselect the mux when it is not required. The DG407 family includes sixteen analog switches, a binary channel-selection decoder, a voltage reference for logic thresholds, and an enable input for device selection. This integrated addressing arrangement reduces the number of external control components required in multiplexed analog systems. The Analog Devices product page also identifies the DG406 and DG407 devices as pin-compatible plug-in upgrades for the industry-standard DG506A and DG507A families, supporting design migration without changing the board footprint. Typical uses include selecting among multiple sensors in a data-acquisition system, routing audio signals between functional blocks, multiplexing instrumentation channels, and directing control signals in communication equipment. Because the mux contains two 8:1 sections, adjacent channel pairs can also be combined as differential or paired selections where the system architecture requires it. The principal design trade-off is the 100-ohm maximum on-state resistance, which can introduce signal attenuation and distortion compared with lower-resistance switching networks. PCB designers should keep analog traces short and provide a stable ground reference beneath the PLCC while separating sensitive inputs from switching or digital return currents. Power and ground connections should be decoupled close to the device, and unused digital inputs should be driven to a defined logic level rather than left floating. The manufacturer datasheet should be consulted for the exact pin assignments, truth table, control timing, electrical limits, and recommended operating conditions before layout or firmware is released. This product record combines verified manufacturer and distributor information, package and pricing references, pin-compatible alternatives, application guidance, and practical selection considerations. It is intended to support sourcing and engineering evaluation while preserving explicit markers wherever the supplied source material does not expose a verified parameter.

DG408 - 8-Channel CMOS Analog Multiplexer 100Ω | Renesas

The Renesas DG408 is a single 8-channel CMOS analog multiplexer with 100 ohm maximum on-resistance, 15 pC maximum charge injection, and 1.25 mW maximum power consumption, housed in a 16-pin package (PDIP, SOIC, TSSOP options). An analog multiplexer is a signal-routing device that selects one of several analog inputs and connects it to a single output using an array of CMOS transmission gates controlled by digital address inputs. In the signal-chain hierarchy, the DG408 sits between sensors or signal sources and an ADC or amplifier, functioning as a digitally controlled switch matrix within the broader family of analog switches and multiplexers in data acquisition systems. Key features include guaranteed channel-to-channel on-resistance matching of 8 ohms max and on-resistance flatness of 9 ohms max, which preserve signal accuracy when switching between channels. The device offers TTL/CMOS-compatible digital inputs over the full operating temperature range, an ENABLE input for paralleling multiple muxes, and break-before-make switching to prevent momentary channel shorting. ESD protection exceeds 2000 V per datasheet specifications. Technically, the DG408 integrates eight CMOS analog switches, a TTL/CMOS-compatible 3-bit decoder, an internal voltage reference for logic thresholds, and an enable circuit on one monolithic die. Rail-to-rail analog signal handling allows the full supply range to be switched, and input leakage current is limited to 5 nA max at +85C, minimizing signal errors in high-impedance paths. Typical applications include high-speed data acquisition front ends, audio signal switching and routing, automatic test equipment (ATE) systems, and avionics, where its low leakage and fast, clean switching fit dense channel-scanning designs. When designing with the DG408, observe the break-before-make timing margin and keep the digital address lines clean, as slow edges can cause transient feedthrough during decoding.

DG408CY+

DG408CY+ - 8:1 CMOS Analog Multiplexer, 16-SOIC | Maxim Integrated

The Maxim Integrated DG408CY+ is an 8:1 CMOS analog multiplexer in a 16-pin narrow SOIC package, featuring 100Ω maximum on-resistance and 15pC maximum charge injection. It selects one of eight analog inputs through three digital control inputs and supports bidirectional signal conduction, making it suitable for multiplexed measurement, instrumentation, data acquisition, and control systems. The device also provides rail-to-rail signal handling, TTL/CMOS-compatible controls, and low power consumption of 1.25mW maximum. What is an analog multiplexer? An analog multiplexer is an analog switch that connects one common terminal to one of several input terminals. The DG408CY+ belongs to the CMOS analog switch and multiplexer hierarchy, where CMOS circuitry controls low-resistance, bidirectional signal paths. In a typical system, address logic selects a sensor, voltage source, or measurement channel, while the common terminal routes that signal to an ADC, amplifier, or signal-processing circuit. The DG408 can also be used as a demultiplexer when the design requires distributing a signal toward multiple destinations. Key verified features include guaranteed channel matching of 8Ω maximum, on-resistance flatness of 9Ω maximum, maximum on-resistance of 100Ω, and maximum charge injection of 15pC. Input off-leakage is specified below 5nA at 85°C. The device uses TTL/CMOS-compatible digital input control and includes ESD protection exceeding 2000V according to the listed product information. Its 16-pin narrow SOIC package supports conventional surface-mount assembly while keeping the analog signal routing compact. The improved DG408CY+ design emphasizes repeatable channel behavior across the specified signal range. This matters when multiple measurements are compared in instrumentation, automated test equipment, or data-acquisition systems because channel mismatch can create systematic measurement error. Its bidirectional conduction also allows the common signal path to be used according to the system architecture, although external protection and input-voltage limits must be respected. Typical uses include switching analog inputs into an ADC, selecting external sensors, routing test signals, implementing sample-and-hold front ends, and controlling laboratory or industrial measurement equipment. For high-impedance sources, leakage and off-state behavior can be important; for low-impedance signals, on-resistance and charge injection deserve attention. The DG408CY+ is therefore most appropriate when a compact, multiplexed analog-routing solution is needed with verified low-leakage and controlled charge-injection behavior. When laying out the circuit, keep analog traces short and route control signals away from sensitive analog nodes. Confirm that supply voltage, logic levels, input voltage range, and switch-cycle timing meet the device requirements before use. This page consolidates distributor information, verified datasheet features, package details, and design guidance for engineers evaluating the DG408CY+.

DG408DJ+ - 8-Channel 100Ω CMOS Analog Mux | Analog Devices

Analog Devices DG408DJ+ is an improved 8-channel, single-ended CMOS analog multiplexer with 100 ohm on-resistance, 8:1 signal routing, and a 16-pin PDIP package. Designed for bidirectional analog conduction, it connects one of eight inputs to a common output according to three binary address inputs, A0, A1, and A2. It can also be used as an 8-channel demultiplexer when signal-flow requirements permit. An analog multiplexer is a semiconductor switching network that routes multiple analog inputs onto a shared output path. The DG408DJ+ belongs to the analog switch and multiplexer hierarchy and combines eight switch elements, TTL/CMOS-compatible channel decoding, and device-enable control in one integrated circuit. This integration reduces discrete switching hardware in data-acquisition, test, communication, guidance, and control systems. The verified product information identifies a nominal 100 ohm on-resistance, 15 pC maximum charge injection, and input off-leakage below 5 nA at 85°C. Its equal bidirectional conduction makes the device suitable for routing signals where the source and destination roles can change. The three address inputs determine the selected channel, while the enable control allows the device to be removed from active service without changing the board interface. The DG408DJ+ is identified as an improved member of the DG408 family and as a pin-compatible upgrade for the industry-standard DG408. Analog Devices lists audio-signal routing, communication systems, data acquisition, guidance and control systems, sample-and-hold circuits, and test equipment among its applications. These uses illustrate why switching bandwidth, on-resistance, leakage, and control compatibility must be evaluated together. A primary design advantage is the ability to consolidate an eight-way analog routing matrix into one 16-pin IC. Logic-grounded address and enable signals control the selected path, while the common analog node reduces the number of external routing connections. Engineers should still verify signal amplitude, bandwidth, settling behavior, supply requirements, and all device limits against the current Analog Devices datasheet before releasing a production design. When sourcing a replacement, preserve the 16-pin PDIP footprint and confirm pin-level compatibility rather than relying only on the DG408 family name. Similar multiplexers can differ in address decoding, enable polarity, injection, leakage, supply range, and electrical performance. The official Analog Devices product page and datasheet remain the controlling sources for those details. This page combines verified distributor availability, manufacturer documentation, functional application analysis, and same-footprint replacement guidance. It is intended to help engineers identify the DG408DJ+, locate its documentation, understand its multiplexing role, and plan a technically defensible sourcing or replacement decision.

DG408DY+

DG408DY+ - 8-Channel 100Ω CMOS Multiplexer | Analog Devices

Analog Devices DG408DY+ is a single 8-channel CMOS analog multiplexer with an 8:1 configuration, 100Ω maximum on-resistance, and a 16-SOIC package. Designed for routing one of eight analog inputs to a common output, it combines a TTL/CMOS-compatible decoder with low-power monolithic switch arrays for data acquisition, signal routing, test equipment, and instrumentation. An analog multiplexer is an interface IC that connects multiple input channels to one shared signal path. The DG408 family extends this hierarchy from analog switch to multiplexer, analog interface, and integrated circuit. Its eight independently addressed channels reduce the number of external pins and board-routing requirements when a system must sample or route several sensor, measurement, or test signals through one analog-to-digital converter or processing channel. Key features include a maximum on-resistance of 100Ω, guaranteed channel matching of 8Ω maximum, and signal-range flatness of 9Ω maximum. These specifications help minimize gain or attenuation differences among channels. The TTL/CMOS-compatible digital control accepts common logic levels, while the monolithic CMOS implementation supports low power dissipation for battery-operated and remote instrumentation systems. The DG408 architecture uses eight analog switches, a binary decoder, and a common output arrangement. Because it is a single-ended multiplexer, the DG408 routes eight channels to one output; the closely related DG409 provides a differential four-channel arrangement. Channel matching and flatness limits are particularly important when calibration assumes that all eight positions present nearly identical resistance. The 16-SOIC package supports conventional surface-mount PCB assembly. Typical applications include high-speed data acquisition, audio signal switching and routing, automatic test equipment, avionics, battery-powered instruments, and remote measurement systems. In each case, the multiplexer's low channel variation supports repeatable measurements, while its on-resistance remains suitable for many moderate-impedance sources. Signal bandwidth, input impedance, settling time, and source drive capability must be checked together when establishing an acquisition system's accuracy. For layout, keep the selected analog path short and route all eight channels consistently to reduce crosstalk and propagation mismatch. Place input protection and conditioning networks close to the mux pins, maintain a continuous ground reference, and avoid long parallel routes beneath noisy digital signals. Use the manufacturer's pin-description table when assigning supply, enable, address, common, and output connections. This product page combines the manufacturer's DG408 documentation with parameter-level comparison, replacement guidance, and practical PCB design considerations. It is intended to help engineers evaluate channel architecture, logic compatibility, package constraints, and signal-integrity requirements before integrating the DG408DY+ into a new analog routing system.

DG409CJ+ - Dual 4:1 CMOS Multiplexer | Analog Devices

Analog Devices DG409CJ+ is a dual 4:1 CMOS analog multiplexer with 100 ohm maximum on-resistance, 150 ns switching performance, and a 16-pin DIP package. The device supports supply voltages from 5 V to 30 V, operates as two independent 4-position analog switches, and provides break-before-make behavior for applications requiring isolated signal paths. An analog multiplexer is an interface IC that routes one of several input signals to an output terminal under digital control. The DG409 family is described as an improved 8-channel or dual 4-channel CMOS analog multiplexer. In each 4:1 section, four inputs share one output, while separate address-select inputs determine the active path. This places the device in the analog switch and multiplexer hierarchy within broader signal-routing and interface semiconductor systems. Key features include a maximum on-resistance of 100 ohm, 150 ns switching time, low off leakage current of 500 pA, and operation across a 5 V to 30 V supply range. The manufacturer also identifies guaranteed channel matching of 8 ohm maximum and signal-range flatness of 9 ohm maximum for the redesigned DG408 and DG409 families. These characteristics help minimize gain error, channel-to-channel mismatch, and distortion when routing precision analog signals. The DG409CJ+ uses CMOS multiplexing architecture with separate control logic for the two 4:1 sections. Break-before-make switching prevents the incoming and outgoing paths from conducting simultaneously during transition, reducing signal contention in test, measurement, and instrumentation systems. The 16-DIP package provides through-hole mounting and approximately 7.62 mm lead pitch according to the verified distributor listing. Typical uses include automated test equipment, data acquisition, analog signal routing, industrial control, instrumentation, and communications systems. One multiplexer section can select among four sensor outputs while the other routes a separate group of four inputs, allowing a compact dual-bank routing architecture. Designers must also account for the relatively high on-resistance compared with modern low-resistance multiplexers when driving high-impedance or high-capacitance loads. For PCB design, place the DG409CJ+ close to the routed analog signals to minimize trace capacitance and pickup. Confirm logic levels and supply tolerances before decoding address inputs, and verify downstream loading because the 100 ohm maximum path resistance can create signal attenuation with a finite input impedance. This page combines verified manufacturer and distributor information, drop-in family alternatives, application guidance, and a parameter-by-parameter comparison. It also identifies unavailable electrical details explicitly rather than estimating unverified values, helping engineers evaluate the DG409CJ+ for new designs and legacy replacements.

The DG409 family is identified as a production product by Analog Devices. An analog multiplexer is an interface IC that connects multiple analog signal paths to a shared output while preserving the selected signal. The DG409DY+ belongs to the CMOS analog multiplexer hierarchy, where four channels and two switch circuits provide bidirectional signal routing for differential or paired single-ended measurements. Its differential 4:1 organization makes it more appropriate than an 8:1 single-ended multiplexer when a system must preserve two related signals together. Key features include two 4:1 analog switch circuits, maximum on-resistance of 100 ohm, and a 16-SOIC package. According to the manufacturer product page, the redesigned DG408 and DG409 devices provide guaranteed matching between channels of 8 ohm maximum and signal-range flatness of 9 ohm maximum. These channel-matching and flatness characteristics help minimize errors when different input sources feed downstream conversion or measurement circuitry. The DG409 architecture uses monolithic CMOS switches and TTL/CMOS-compatible control inputs, allowing microprocessor, microcontroller, or logic-level addressing. The mux provides low on-resistance in either signal direction, making the selected channels suitable for bidirectional routing. Designers should still account for switch resistance, off-channel leakage, supply limits, settling behavior, and the analog signal range when determining whether the architecture meets an application's accuracy and bandwidth targets. Typical applications include differential sensor acquisition, automated test equipment, data acquisition systems, sample-and-hold networks, signal routing for measurement front ends, and multiplexed control paths. The DG409DY+ is particularly useful when several sensors or test nodes must be selected without duplicating a complete analog front end. Its two independent 4:1 sections also permit simultaneous selection of two related channels.

DG411 - Quad SPST CMOS Analog Switch, 35 Ohm | Analog Devices

The Analog Devices DG411 is a precision monolithic quad SPST CMOS analog switch featuring four independent single-pole single-throw switches with a maximum on-resistance of 35 ohm, a 44V maximum supply range, and TTL/CMOS-compatible digital inputs, housed in a 16-pin SOIC package. A quad SPST analog switch is an integrated circuit that contains four independent electronically controlled switches for passing or blocking analog signals. Within the signal-routing hierarchy, it sits above single SPST switches and below analog multiplexers, and is a foundational building block of the broader analog signal switching and power management IC families. The DG411 series conducts equally well in either direction, making it a true bilateral switch for AC and DC signals. Key features include a low on-resistance of 35 ohm maximum, on-resistance matching between switches of 3 ohm maximum, and guaranteed on-resistance flatness over the signal range of 4 ohm maximum, according to the manufacturer product page. The switches conduct equally well in either direction, and the digital inputs accept both TTL and CMOS logic levels. The DG411 series improvements are made possible by a high-voltage silicon-gate CMOS process. An epitaxial layer prevents the latch-up associated with older CMOS technologies. The 44V maximum voltage range permits controlling 40VP-P signals. Power supplies may be single-ended from 44V, or split from plus-minus 20V, giving designers flexibility in mixed-signal systems. Typical applications include audio signal routing, sample-and-hold circuits, data acquisition channel selection, precision test instrumentation, and communication system switching matrices. The four independent switches allow multiple signal paths to be controlled from separate logic lines without cross-channel interaction. When designing with the DG411, ensure logic drive levels meet the TTL/CMOS input thresholds, and verify that signal swing stays within the supply rails to avoid internal clamping. Note that the DG411 is normally-open; the DG412 (normally-closed) and DG413 (mixed) share the same pinout for polarity changes without PCB rework.

DG411CJ+

DG411CJ+ - Quad SPST Analog Switch | Analog Devices

Analog Devices DG411CJ+ is an improved quad, single-pole single-throw analog switch with four independent normally closed switch circuits and TTL- and CMOS-compatible control inputs. It is supplied in a 16-pin PDIP package for through-hole PCB installation. The manufacturer identifies the DG411 family as production devices and describes the switch family as low-on-resistance matching and flatness designs, with on-resistance matching up to 3 ohms and signal-range flatness up to 4 ohms. An analog switch is an integrated semiconductor device that routes analog or digital signals under electronic control. In the broader hierarchy, an analog switch belongs to interface ICs, alongside multiplexers, demultiplexers, and switch matrices. The DG411CJ+ is useful when a system must connect, isolate, sample, or route four independent signal paths without using mechanical relays. Key benefits of the DG411 family include matched behavior among the four switches, low on resistance, fast switching, and CMOS-compatible logic control. The normally closed topology means each switch conducts when its control input is in its inactive state and opens when commanded. This behavior can simplify fail-safe signal paths, though exact control-state interpretation should be confirmed from the manufacturer datasheet before implementation. The DG411 family comprises multiple package and temperature options. The CJ+ ordering code specifically identifies the 16-pin PDIP package, so it should not be confused with surface-mount or military-package variants. Its through-hole format is useful for legacy instrumentation, laboratory equipment, industrial controls, and hand-built or low-volume systems where SOIC or dual-inline-package assembly is preferred. Typical uses include multimeter and test-equipment signal routing, sample-and-hold paths, industrial sensor interfaces, audio test systems, and analog measurement chains. Because the device is an integrated circuit rather than a power semiconductor, a safe operating area chart is not applicable. Thermal and switching analysis should instead consider package dissipation, control timing, signal amplitude, load impedance, and the selected external circuitry. The principal design consideration is package interchangeability. Verify the CJ+ package suffix, pin orientation, and SPST normally closed behavior against the current manufacturer datasheet before substitution. PCB layout should keep control traces away from sensitive analog paths, use a solid ground reference, and place protection or settling networks where required by the source and destination impedances.

The Analog Devices DG411DJ+ is a four-channel, single-pole single-throw CMOS analog switch with a 45 ohm on resistance, operating from 10 V to 30 V in a 16-pin PDIP package. The four independent normally closed switches support 1:1 signal routing and are controlled by TTL- and CMOS-compatible logic inputs. 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.

The Analog Devices DG411DY+ is a 4-channel, single-pole single-throw CMOS analog switch with 45 Ω maximum on-resistance, TTL- and CMOS-compatible control inputs, and a 16-pin SOIC package. The four independent switches route one source terminal to one drain terminal each, making the device suitable for analog signal selection, test systems, instrumentation, and signal isolation. An analog switch is a solid-state semiconductor that connects or disects an analog signal path under digital control. The DG411 belongs to the analog switch and multiplexer hierarchy, where multiplexers combine multiplexing or demultiplexing functions and analog switches provide individual routing paths. Its CMOS implementation offers low power requirements and compatibility with digital control systems, while the normally closed architecture provides a defined connection state when control signals are absent. Key verified characteristics include four independent SPST channels, a 1:1 signal configuration, 45 Ω maximum on-resistance, and a 16-SOIC package. The manufacturer identifies the DG411 family as improved, with low on-resistance matching between switches of 3 Ω maximum and guaranteed on-resistance flatness of 4 Ω maximum over the signal range. These characteristics are important when several channels must present similar resistance to precision measurement or acquisition circuits. The DG411 series is designed around low on-resistance matching and flat on-resistance behavior. Matching reduces channel-to-channel gain or measurement variation, while flatness helps preserve signal behavior as the analog voltage changes. The family uses TTL- and CMOS-compatible digital inputs, allowing its control signals to be driven by common digital logic while switched signals remain in the analog domain. Typical uses include battery-powered test equipment, automated measurement interfaces, signal routing in instrumentation, communication equipment, and data-acquisition systems. Because the device is an analog switch rather than an amplifier, ADC accuracy also depends on source impedance, settling behavior, leakage, reference quality, and the surrounding signal chain. The verified source data does not provide complete timing, leakage, supply-current, and absolute-maximum-rating values, so those specifications require confirmation from the manufacturer datasheet before design release. The principal design consideration is verifying control levels, supply arrangement, signal excursion, and channel polarity against the complete datasheet. Place the device close to the source and destination circuits to minimize trace resistance and capacitance. Account for 45 Ω maximum on-resistance in the signal-path budget, especially for high-value sources or precision dividers. Do not infer ratings from a distributor category listing alone; use the manufacturer datasheet for electrical limits and test conditions. This product data combines the verified manufacturer overview, distributor package and pricing references, and practical replacement guidance. It distinguishes documented facts from unavailable parameters, helping engineers evaluate DG411DY+ for routing applications without inventing missing electrical data.

An analog switch is a semiconductor device that routes or blocks analog signal paths under digital control, sitting within the broader taxonomy: analog switch IC -> signal switch -> interface/signal-conditioning IC -> semiconductor. Quad SPST switches like the DG411 are the workhorses of analog front-end design, replacing electromechanical relays and discrete JFET switching where board space, speed, and reliability matter. Key features include extremely low power consumption of approximately 0.35 uW, TTL- and CMOS-compatible digital inputs, and low on-resistance matching between the four switches. The CMOS transmission-gate architecture conducts equally well in either direction, supporting bipolar analog signal swings when dual supplies are used. The -E3 suffix denotes tin/lead-free plating with RoHS compliance for modern assembly processes. Technically, each switch is built as a CMOS transmission gate with an n-channel and p-channel MOSFET in parallel, driven by level-shifting gate control circuitry derived from the digital input. This topology keeps on-resistance relatively flat over the analog signal range and minimizes charge injection, which is critical for sample-and-hold, integrator-reset, and audio signal-routing accuracy. Typical applications include audio and video signal switching, precision test-and-measurement signal routing, sample-and-hold circuits, and data-acquisition channel multiplexing, where its 35 ohm channel resistance and low quiescent power keep inserted errors and thermal drift small. Designers should verify total supply voltage headroom: the DG411 family is specified for dual supplies in the region of plus/minus 15 V, and signal swings must remain within the supply rails to avoid latch-up or increased distortion.

DG412CJ+ - 4-Channel SPST Analog Switch | Maxim Integrated

The Maxim Integrated DG412CJ+ is a 4-channel, independently controlled SPST analog switch IC with a 45 Ω on-resistance specification, housed in a 16-pin PDIP package. The device is designed for signal routing in test, measurement, communication, and industrial control systems where four separate analog paths must be selected with low distortion and controlled resistance. An analog switch is an interface IC that connects or disconnects a signal path under digital control. The DG412CJ+ belongs to the analog switch family, which sits within interface ICs and broader semiconductor signal-routing systems. Its four SPST channels provide simple on/off selection rather than multiplexing several inputs onto one output. This makes it suitable for bypassing, routing, isolation, and test-fixture applications where the signal must preserve amplitude and waveform integrity. The verified product information identifies the DG412CJ+ as an improved, quad, SPST analog switch. Maxim describes the DG411, DG412, and DG413 family as featuring low on-resistance matching between switches, with a maximum matching value of 3 Ω, and guaranteed on-resistance flatness over the signal range, with a maximum flatness difference of 4 Ω. These characteristics help reduce channel-to-channel variation and signal amplitude errors in precision analog paths. The manufacturer product page also lists a 1ku list-price starting point of $3.68. The CJ+ ordering code uses the manufacturer’s 16-pin PDIP package, making it appropriate for through-hole prototyping, educational platforms, and legacy or industrial assemblies where a socketed DIP footprint is preferred. The four control inputs are intended for digital control, while the switched terminals carry analog signals. The design must still be checked against the complete datasheet for absolute maximum ratings, switch configuration, control logic, charge injection, off leakage, and operating limits. Typical uses include selecting one of several sensor outputs, isolating instrumentation inputs, controlling analog test paths, routing audio or communication signals, and implementing sample-and-hold or measurement front ends. Because the device is a physical switch rather than an active amplifier, system performance depends on source impedance, signal amplitude, control timing, parasitic capacitance, and PCB leakage. Use a ground plane, short analog traces, and an appropriate bypass strategy when integrating it into a mixed-signal board. The DG412CJ+ is a sensible choice when four independent SPST paths, a DIP package, and low matched on-resistance are required. For a new compact design, a surface-mount equivalent may simplify assembly; for a different multiplexing architecture, a mux or demux device should be considered instead. This page combines the verified manufacturer and distributor information with practical selection, application, and design guidance.

DG412DJ+ - 45Ω Quad SPST Analog Switch | Maxim Integrated

The Maxim Integrated DG412DJ+ is a four-channel, single-pole single-throw CMOS analog switch rated for a maximum 44 V supply and a 15 V analog signal range. Its four independent SPST switches provide 1:1 signal routing in a 16-pin PDIP package. The device is specified with 45Ω on-resistance, 110 ns turn-on time, and low power dissipation of 0.35 mW. An analog switch is a semiconductor device that connects or isolates an analog signal path under digital control. The DG412DJ+ belongs to the analog switch hierarchy, where CMOS switching transistors replace mechanical contacts for faster operation, compact integration, and electronic control. Its four independent channels can each connect one analog terminal to one switched terminal, making the device suitable for signal multiplexing, sampling, test-point isolation, and routing systems. The principal features include four independent SPST switches, a 44 V maximum supply rating, and a 15 V analog signal range. According to the manufacturer datasheet, on-resistance matching between switches is maintained to 3Ω maximum, while guaranteed on-resistance flatness across the signal range is 4Ω maximum. These characteristics help reduce channel-to-channel resistance variation when the same control sequence drives multiple signal paths. The DG412DJ+ uses TTL- and CMOS-compatible digital inputs, allowing straightforward interfacing with microcontrollers, FPGA I/O, and logic families. Its 110 ns turn-on time supports faster signal-path changes than traditional relay-based implementations. The monolithic CMOS construction also enables low power dissipation, with the datasheet listing 0.35 mW for the characterized operating condition. Typical applications include multiplexed sensor acquisition, audio and communication signal routing, automated test equipment, data acquisition systems, and general-purpose analog signal isolation. The four-channel arrangement is especially useful when several independent sources must be selected without using mechanical relays. Signal integrity and transient requirements should still be checked against the actual source impedance, load, bandwidth, and supply conditions. For PCB implementation, use the 16-pin PDIP footprint and route the digital control signals to minimize switching noise coupling into sensitive analog nodes. Decoupling capacitors should be placed close to the supply and ground pins, while switched analog traces should be kept short and away from control clocks. Confirm absolute maximum ratings, logic thresholds, and off-state isolation before finalizing the design. This product page combines manufacturer specifications, package details, application guidance, and same-footprint replacement information to support faster component evaluation. It also highlights the principal trade-offs engineers should assess: on-resistance variation, switching speed, logic compatibility, power dissipation, and the mechanical constraints of a through-hole PDIP package.

An analog switch is a semiconductor device that routes or blocks analog signal paths under digital control, acting like a relay but with far higher speed, lower power, and smaller size. Within the signal-routing hierarchy, the analog switch sits below analog multiplexers (which select among many channels) and above transmission gates, forming a fundamental building block of the broader analog front-end and signal-conditioning IC family. The DG412 provides four normally-closed SPST switches, while its DG411 and DG413 family siblings provide normally-open and mixed configurations. Key features include low on-resistance (35 ohm max), extremely low power consumption of 0.35 uW, TTL and CMOS compatible digital inputs, and fast switching of precision analog signals. The monolithic CMOS construction ensures matched switch characteristics and low charge injection, preserving signal integrity in precision measurement paths. Architecturally, each channel is a CMOS transmission-gate switch driven by a level-shifting logic interface, allowing digital control signals referenced to logic supplies to switch analog signals riding on dual ±15V rails. This is the classic precision switch topology inherited from the DG211/DG212 generations; per the manufacturer documentation, the DG411 series is a drop-in replacement for DG211/DG212 devices. Typical applications include sample-and-hold circuits, precision integrators and peak detectors, audio and instrumentation signal routing, and test-equipment channel switching, where quad SPST control with low error switching is required. A key design consideration: with 35 ohm on-resistance, ensure downstream load impedances remain high (100x switch resistance or more) to limit gain error, and always observe the ±13.5V to ±16.5V supply range with appropriate supply decoupling.

An analog switch is a semiconductor device that routes or blocks analog signal paths under digital control. Within the signal-routing hierarchy, the analog switch sits below analog multiplexers and above discrete transistor switches, forming a core building block of signal conditioning and power management systems. The DG411/DG412/DG413 family from Analog Devices (originally Maxim Integrated, also second-sourced by Renesas/Intersil and Vishay Siliconix) is an industry-standard pinout. Key features include TTL- and CMOS-compatible digital inputs, operation from a single +10V to +30V supply or bipolar ±4.5V to ±20V supplies, and a 44V silicon-gate process with an epitaxial layer that prevents the latch-up associated with older CMOS technologies. The improved family offers lower on-resistance (35 ohm vs. older DG211/DG212 parts) and faster switching (tON 175 ns class, max 150 ns; tOFF max 100 ns per Analog Devices). Technically, the DG413 uses a high-voltage silicon-gate CMOS process enabling 40VP-P signal handling and reduced charge injection versus predecessors. It is a drop-in replacement for the popular DG211/DG212 series. Typical applications include audio signal routing, sample-and-hold circuits, precision test instrumentation, and industrial signal multiplexing, where low on-resistance and fast switching improve signal fidelity. Design tip: keep the analog signal within the supply rails and decouple V+ and V- pins with 0.1 uF ceramics to preserve charge-injection performance.

Analog Devices DG413CJ+ is a four-channel, single-pole single-throw analog switch with a maximum on-resistance of 45 ohm, a maximum switching time of 145 ns, and a PDIP-16 through-hole package. The verified product information identifies four normally open SPST switches, a supply range of ±4.5 V to ±20 V, and an operating temperature range of 0 C to +70 C. It is designed for routing analog signals in test, measurement, instrumentation, and signal-conditioning systems where four independent channels must be switched from common control circuitry. 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.

Designed for high-speed, low-error routing of analog signals, the DG413DY+ operates from single or dual supply rails and accepts signals ranging between 4.5 V and 30 V. An analog switch is an integrated circuit that connects or disconnects signal paths under digital control. The DG413DY+ belongs to the CMOS analog switch hierarchy, where each of its four single-pole, single-throw channels can independently route a source terminal to one of two possible signal paths. This makes the device useful when a system must select among sensors, measurement channels, test points, or external circuit branches without introducing mechanical relays. Key features include four independent SPST switches, 1:1 signal routing, a maximum on-resistance of 45 Ω, low on-resistance matching between switches of 3 Ω maximum, and on-resistance flatness of 4 Ω maximum over the signal range. The device uses CMOS-compatible control inputs and supports improved conduction in either signal direction. These characteristics help preserve signal integrity in precision measurement, test, instrumentation, and communication circuits. The DG413 family uses an enhanced CMOS process to combine low power dissipation, high switching speed, and low on resistance. Because the switches provide equal electrical performance in both directions, a PCB designer can use consistent routing practices for paired signal paths. The manufacturer emphasizes improved matching and flatness because these characteristics directly influence gain error, channel-to-channel variation, and the accuracy of analog measurements passing through the switch. Typical uses include battery-powered instrumentation, automated test equipment, data-acquisition systems, communication routing, sample-and-hold front ends, and precision sensor interfaces. The DG413DY+ can support acquisition of multiple analog inputs where each channel requires independent selection while keeping control logic compatible with modern CMOS systems. Its four-channel structure reduces the number of separate switch packages needed in a typical measurement front end. When laying out the circuit, route each switched signal through a symmetric path and keep digital control traces away from sensitive analog nodes. Confirm the actual supply voltage, input-signal range, switch logic levels, and absolute maximum ratings in the manufacturer datasheet before connecting external circuitry. The 16-SOIC footprint also allows board updates where the four analog channels can replace discrete or multiplexed switching arrangements.

DG417AK - 35 Ohm SPST Analog Switch IC | Vishay Siliconix

The Vishay Siliconix DG417AK is a precision CMOS monolithic analog switch packaged in an 8-lead SOIC, configured as a single SPST normally-closed (NCX1) channel with a maximum on-resistance of 35 ohm and a typical on-resistance of 20 ohm. It is designed for the +/-15 V analog signal range and drives both TTL and CMOS control logic, making it a drop-in fit for legacy instrumentation and test equipment. An analog switch is a semiconductor device that routes an analog signal between circuit nodes under digital control. The DG417 belongs to the broader family of analog switches and multiplexers, which sit between sensors, amplifiers and converters on one side, and a shared signal chain on the other. A single-pole single-throw (SPST) switch provides one signal path that is either connected or broken, while a normally-closed version holds the path closed until a control signal opens it, which is the safe default for fail-safe routing. Key features include guaranteed on-resistance matching between switches of 3 ohm max and guaranteed on-resistance flatness across the signal range of 4 ohm max, both improvements over earlier generations of this device family. Fast switching action is specified at tON = 100 ns, and ultra-low power requirements of PD = 35 nW keep the supply current draw negligible in battery-backed and standalone measurement fixtures. The design is CMOS monolithic, so the part draws essentially no quiescent bias current. Because the switch is CMOS and complementary-driven, the control pins accept TTL and CMOS levels, and the input stage tolerates a wide analog signal range of +/-15 V on the switched terminals. On-resistance matching and flatness specifications are what make the device usable for precision measurement: they bound the error introduced when the same source impedance drives different switched paths, which is the dominant error term in many 16-bit and 18-bit front ends. Typical applications include sample-and-hold front ends for high-resolution ADCs, precision instrument amplifiers in test and measurement systems, audio and low-frequency signal routing in broadcast and studio equipment, medical monitoring front ends, and general-purpose routing in industrial control and data acquisition modules. The primary design consideration is the always-present 35 ohm series resistance in the closed state, which must be included in the system noise and offset budget; keep the switch close to the high-impedance input it serves so that leakage and stray capacitance do not degrade accuracy. Because the DG417AK is a legacy order code, confirm supply availability and consider the currently active equivalents listed below for new designs.

The Maxim Integrated DG417CJ+ is a single-pole single-throw (SPST) precision CMOS analog switch with a typical on-resistance of 35 ohm, supplied in an 8-pin PDIP package. It is designed for low-voltage analog signal routing in test, measurement, communication, and instrumentation systems. The device provides one independently controlled switch path, complementary switching behavior, low charge injection, and bidirectional signal conduction. According to the manufacturer datasheet, the DG417 family also guarantees on-resistance matching within 3 ohm maximum between switches and on-resistance flatness within 4 ohm maximum across the signal range. An analog switch is a semiconductor device that routes an analog voltage or current between circuit nodes under digital control. In system terms, an analog switch belongs to the interface IC category, where it connects to multiplexers, sample-and-hold circuits, and signal-conditioning networks. Unlike a mechanical relay, the DG417CJ+ changes state electronically without moving mechanical contacts, allowing compact, reliable, and fast signal-path control. The DG417CJ+ offers a rated on-resistance of 35 ohm, low charge injection, low power consumption, and an ESD tolerance of 2000 V. Its precision monolithic CMOS construction supports consistent switching behavior over the usable signal range. The switch operates equally well in either signal direction, making it useful where the source and destination roles can reverse during a measurement or test sequence. The device is available in a commercial temperature grade, and the 8-pin PDIP package is suitable for through-hole assembly, prototype boards, educational laboratories, and legacy industrial equipment. The DG417C version is the leaded commercial-temperature option; the '+' ordering suffix identifies the modern ordering designation used for the same device family. A companion DG417DJ and related MAX4504 devices use comparable 8-pin DIP configurations, but control polarity, voltage limits, and operating-temperature ranges must be confirmed before substitution. Typical uses include routing sensors to a measurement amplifier, selecting inputs in automated test systems, switching references in laboratory equipment, and controlling analog signal paths in communication hardware. Because the device presents about 35 ohm in the closed state, it is best suited to moderate-impedance analog nodes rather than high-current power switching or low-impedance precision-adcitor front ends where switch resistance would degrade accuracy. For layout, keep the analog signal traces short and connect the supply pins to a low-impedance ground plane. Place any bypass capacitor close to the device, avoid routing control signals beneath sensitive analog nets, and confirm that the switched voltage remains within the datasheet limits. The maximum and recommended operating voltages, supply current, leakage current, switching time, and temperature limits should be taken directly from the manufacturer datasheet for the selected part variant. This page combines package, pin, application, and substitution information with practical PCB and signal-integrity guidance. It is intended to help engineers confirm whether the DG417CJ+ fits a legacy analog-routing design before ordering a new PCB.
