DG406DJ+ - 16-Channel CMOS Analog Multiplexer | Maxim
Артикул: DG406DJ+ ✓ АктивенDG406DJ+ Обзор
A CMOS analog multiplexer is an analog switch network that connects one selected input signal to a common output while blocking the unselected paths. The DG406 belongs to the broader analog switch and signal-routing hierarchy, where low on-resistance, low leakage, controlled charge injection, and accurate channel matching determine how faithfully a measurement or audio signal passes through the selected channel.
The DG406 family provides guaranteed channel-to-channel matching of 8 ohm maximum and on-resistance flatness of 9 ohm maximum across the specified signal range. Maximum on-resistance is 100 ohm, maximum charge injection is 15 pC, and input leakage is 5 nA at +85°C. These characteristics support consistent signal attenuation, low switching transients, and reduced measurement error across the 16 channels.
Internally, the device combines 16 analog switches with a TTL/CMOS-compatible binary decoder, a logic-threshold reference, and an enable input. The four address inputs select one of 16 channels, while ENABLE controls participation in a larger multiplexed system. The DG406 and DG407 families are positioned as pin-compatible plug-in upgrades to the established DG406 and DG407 industry-standard devices.
Typical uses include high-speed data-acquisition systems, automated test equipment, audio routing, avionics, battery-operated instrumentation, and remote measurement platforms. The DG406DJ+ is especially suitable when one analog source must be selected from 16 inputs while keeping channel resistance and capacitance matching under control.
Design the interface around the supported supply range, logic thresholds, address sequencing, and enable timing. Check the maximum signal voltage, ensure every analog pin remains within the supply rails, and account for charge injection when changing channels. A through-hole PDIP footprint also requires adequate board spacing and routing clearance around adjacent high-impedance nodes.

Типичное применение
DG406DJ+ подходит для 6 применениеs: High-Speed Data Acquisition, Automated Test Equipment, Audio Signal Routing, Remote Instrumentation, Avionics Signal Switching, Battery-Powered Sensor Interface.
High-Speed Data Acquisition
The DG406DJ+ fits 16-channel data-acquisition systems where one sensor or conditioned analog input must be routed to a shared converter. Its four address inputs select among 16 inputs, while the enable input permits coordinated operation with other multiplexers. Maximum on-resistance is 100 ohm, channel matching is limited to 8 ohm, and resistance flatness is limited to 9 ohm, helping preserve channel-to-channel consistency. Place the device close to the signal source, use short protected routes, and allow the acquisition system to discard samples during address transitions because maximum charge injection is 15 pC.
Рекомендуется
Automated Test Equipment
In automated test equipment, the DG406DJ+ can route one of 16 test points to a common measurement path while TTL/CMOS-compatible address logic selects the channel. The 100 ohm maximum on-resistance is suitable for many medium-impedance test fixtures, and 8 ohm maximum channel matching supports repeatable comparisons between routed points. Use shielded connections for sensitive signals, separate the digital address traces from high-impedance analog inputs, and select timing in the test controller to account for switching transients associated with the specified 15 pC maximum charge injection.
Рекомендуется
Audio Signal Routing
The DG406DJ+ supports audio source selection where one of 16 inputs must reach a common signal-processing chain. Analog Devices identifies audio signal switching and routing as a DG406 family application, and the device operates from +5 V to +30 V single supply or ±4.5 V to ±20 V dual supply. Its 100 ohm maximum on-resistance can create loss with high source impedances, while 15 pC maximum charge injection can cause a brief switching transient. Use low-impedance audio routing, short ground returns, and pop-control timing when changing channels.
Рекомендуется
Remote Instrumentation
The DG406DJ+ is useful in remote instrumentation because it combines 16-channel selection with low maximum power consumption of 1.25 mW. A single supply from +5 V to +30 V simplifies deployment in battery-operated or distributed measurement systems, while 5 nA maximum input leakage at +85°C helps limit errors in high-impedance sensing paths. Locate the multiplexer near the sensor inputs, protect long cable routes against ESD, and ensure the selected analog signal remains between the applicable supply rails.
Рекомендуется
Avionics Signal Switching
The DG406DJ+ can serve as a signal-routing element in avionics and other controlled test environments where a stable set of analog connections is required. The guaranteed 8 ohm maximum channel matching and 9 ohm maximum on-resistance flatness help maintain consistent behavior across channels, while the 16-channel selection simplifies centralized signal assignment. The PDIP package supports through-hole PCB assembly, but system qualification, ESD protection, operating-temperature requirements, and procurement documentation must be reviewed independently for each aerospace program.
Рекомендуется
Battery-Powered Sensor Interface
The DG406DJ+ fits battery-powered sensor interfaces that need to select among multiple low-bandwidth analog inputs without continuously energizing every measurement path. Its 1.25 mW maximum power consumption reduces switching-system overhead, and the enable input allows the selector to remain inactive when routing is not required. Input leakage of 5 nA maximum at +85°C is important when source impedances are high. Keep leakage-sensitive nodes clean, use a common ground reference, and verify that the selected supply range supports the sensor output amplitude.

Заметки по проектированию
Route the 16 analog inputs as short, properly referenced PCB traces and keep the four address lines away from high-impedance signal paths. The DG406 guarantees 100 ohm maximum on-resistance, 8 ohm maximum channel matching, and 9 ohm maximum flatness, but those analog characteristics cannot compensate for excessive trace leakage or crosstalk. Use a solid ground plane, minimize loop area, and terminate unused analog inputs according to the manufacturer circuit recommendations.
Do not treat a 28-pin PDIP part and a 28-pin SOIC part as interchangeable. The DG406DJ+ uses a through-hole PDIP footprint, while DG406DYZ uses a surface-mount SOIC package; although both provide 28 leads, their pitch and board geometry differ. Also include a settling interval after changing address lines because maximum charge injection is 15 pC, which can create a transient that affects high-impedance measurements.
Confirm whether the design uses the +5 V to +30 V single-supply range or the ±4.5 V to ±20 V dual-supply range before laying out the power connections. Do not allow analog input or output voltages to exceed the applicable supply limits. The datasheet identifies ESD protection greater than 2000 V, but that rating does not replace external surge and ESD protection for cables or externally accessible signal sources.
Place the DG406DJ+ close to the common output and downstream conversion circuitry to minimize the length of the shared output trace. Place protection and filtering components where they will not interfere with the four binary address inputs or enable timing. When cascading multiplexers, use the enable input deliberately and validate the address sequence in hardware to prevent two selected paths from being connected simultaneously.
