DG406CJ+ - 16-Channel CMOS Analog Multiplexer | Analog Devices
Référence : DG406CJ+ ✓ ActifDG406CJ+ Présentation
An analog multiplexer is an analog switch integrated with address-decoding logic that connects one of several inputs to a shared output. The DG406 family belongs to the broader switch and multiplexer hierarchy, which includes analog switches, multiplexers, demultiplexers, interface ICs, and semiconductor signal-routing components. Its CMOS construction and rail-to-rail signal handling make it appropriate for routing signals across a wide common-mode range when the signal remains within the device's stated operating limits.
Key features include low charge injection of 15 pC maximum, low input leakage of 5 nA maximum at +85 °C, and low power consumption of 1.25 mW maximum. TTL-compatible digital controls simplify interfacing with common logic systems. The manufacturer identifies the improved DG406 as a pin-compatible plug-in upgrade for the industry-standard DG406 and DG407 families, making it useful when maintaining existing analog-routing boards.
The internal switch array uses independently controlled analog paths to implement either one 16-channel multiplexer or two 8-channel multiplexers. Address inputs select the active channel, while an inhibit function can place the device in a disabled state. The guaranteed matching and flatness specifications help minimize gain and distortion changes when the selected channel changes, which is important in precision measurement paths.
Typical uses include audio signal routing, communication systems, data-acquisition systems, guidance and control systems, sample-and-hold circuits, and test equipment. These applications benefit from the combination of multiple channels, low leakage, low charge injection, broad supply-voltage options, and compact integration. A design can use one device for a larger 16-channel bank or configure it as two separate 8-channel banks when the system requires independent routing.
When designing around the DG406CJ+, verify that every routed signal stays within the selected supply range and that control levels meet the TTL-compatible input requirements. Treat the maximum on-resistance as part of the source and amplifier impedance budget, and account for charge injection when sampling rapidly changing signals. Use the manufacturer pin-description table when assigning PCB nets and verify the address and inhibit logic in the final system.
This product data combines the manufacturer's device description, identified performance limits, operating applications, and replacement information into an engineering-oriented guide.

Applications typiques
DG406CJ+ convient pour 6 applications: Audio Signal Routing, Communication-System Signal Selection, Data-Acquisition Systems, Sample-and-Hold Circuits, Guidance and Control Systems, Test and Measurement Equipment.
Audio Signal Routing
The DG406CJ+ fits audio routing systems that must connect one of several analog sources to a shared signal path. Its 16-channel configuration can consolidate inputs, while dual 8-channel operation supports two independent routing banks. According to the manufacturer datasheet, the device provides rail-to-rail signal handling and a maximum on-resistance of 100 ohms. These characteristics suit general audio boards where switching loss is acceptable and channel matching helps reduce level changes when a source changes. The 15 pC maximum charge-injection specification should also be considered for precision audio paths. Designers should include the switch resistance in the source-load calculation and keep routed signals within the device's detailed common-mode and supply limits.

Communication-System Signal Selection
The DG406CJ+ can route multiple communication-system signals through a shared analog front end, reducing the number of discrete relays and routing switches needed. The 16-to-1 configuration handles larger banks, while the dual 8-channel mode provides separate routing for two subsystems. Its TTL-compatible control inputs simplify interfacing with common digital control logic, and the manufacturer identifies communication systems as a typical application. The maximum 100-ohm on-resistance must be included in the channel-loss budget, particularly when driving a high-impedance amplifier. Low input leakage of 5 nA maximum at +85 °C also supports applications where leakage could disturb the source node. Control timing and settling should be verified against the complete electrical-characteristics table.
Recommandé
Data-Acquisition Systems
The DG406CJ+ is appropriate for data-acquisition systems that must select among multiple sensor or measurement channels. It can present one 16-channel bank or two independent 8-channel banks to an amplifier, converter, or sampling circuit. The manufacturer identifies data acquisition as a typical application, and guaranteed channel matching of 8 ohms maximum helps control source-resistance differences between selected inputs. Its 5 nA maximum input leakage at +85 °C limits disturbance at high-impedance sources, while the 100-ohm maximum on-resistance contributes to the complete source impedance. For high-accuracy measurements, calculate settling time, switch-induced error, and any required acquisition time after changing the address. Use a low-leakage protection strategy for external sensor inputs.
Recommandé
Sample-and-Hold Circuits
The DG406CJ+ can select among multiple source signals in a sample-and-hold front end before the held value is processed. The 16-channel or dual 8-channel organization allows one multiplexer package to replace several individual switches, while the address controls remain compatible with TTL-level logic. The manufacturer explicitly lists sample-and-hold circuits as a typical application. Charge injection of 15 pC maximum is an important design constraint because the injected charge can create a transient error in the sampling node. Engineers should minimize node capacitance, provide a suitable acquisition interval, and include the switch's 100-ohm maximum on-resistance when determining amplifier bias current and settling behavior. The complete application circuit should also respect the device's absolute signal and supply limits.
Recommandé
Guidance and Control Systems
The DG406CJ+ suits guidance and control systems that must route several analog command or feedback signals through a common processing chain. A dual 8-channel configuration can separate two signal groups, while a single 16-channel mode supports denser routing. The manufacturer identifies guidance and control systems as a typical DG406 application. TTL-compatible address and inhibit controls allow the device to be coordinated by standard control logic, and the 8-ohm maximum channel matching supports more consistent signal levels across selections. System designers should verify whether 100 ohms of maximum switch resistance materially affects actuator feedback or sensor conditioning. Account for 15 pC maximum charge injection in precision feedback loops, and use the inhibit and address sequencing functions to prevent unintended channel transitions during state changes.
Recommandé
Test and Measurement Equipment
The DG406CJ+ is well suited to test-equipment front ends that connect one of several test points to a common instrument channel. The 16-to-1 configuration supports broad matrix-style selection, while the dual 8-channel mode can serve two measurement paths. The manufacturer lists test equipment as a typical application. Guaranteed on-resistance matching of 8 ohms maximum and flatness of 9 ohms maximum help reduce channel-dependent errors, while rail-to-rail handling expands the usable signal range subject to detailed operating limits. Account for the 100-ohm maximum on-resistance when calculating attenuation with the next stage's input impedance. Charge injection of 15 pC maximum should be checked against the sensitivity and bandwidth of the selected measurement node.

Notes de conception
Include the maximum 100-ohm on-resistance in the complete source-impedance calculation. At low source impedances this resistance may have little effect, but it can produce measurable attenuation when driving a high-impedance amplifier or sampling node. The guaranteed 8-ohm channel matching and 9-ohm on-resistance flatness limits help reduce channel-to-channel variation, although the downstream amplifier input impedance and settling time must also be included in the error budget.
Do not treat the address-control and inhibit signals as ordinary high-speed digital interfaces. Allow the address inputs to settle before sampling, and use the manufacturer's recommended acquisition interval when charge injection can affect the measured node. Charge injection is specified at 15 pC maximum, so high-impedance or capacitive sensing nodes may require additional filtering, longer acquisition time, or lower-impedance buffering.
Budget the rails against the stated single-supply limit of +30 V and dual-supply limit of ±20 V, while allowing margin for transients and source-device variation. The manufacturer specifies maximum power consumption of 1.25 mW under defined conditions. Actual board dissipation also depends on supply voltage and control levels, so include the device in the overall power calculation rather than treating 1.25 mW as the only system contribution.
Use the manufacturer pin-description table to assign the 28-pin DIP footprint and verify whether the circuit uses the 16-channel or dual 8-channel arrangement. Keep analog routing traces away from switching nodes and high-current return paths. For sensitive sources, provide a low-leakage protection network and maintain a defined common reference across the selected switch terminals. Confirm the final package orientation and pin numbering against the ordering drawing before fabrication.
