DG406DN+ - 16:1 CMOS Analog Multiplexer | Vishay
N.º da peça: DG406DN+ ✓ AtivoDG406DN+ Visão geral
An analog multiplexer is an interface IC that selects one signal path from multiple analog inputs and connects it to a shared output. This reduces the number of input channels required by a data-acquisition, test, measurement, control, or communication system. The DG406DN+ belongs to the CMOS analog-switch and multiplexer hierarchy, where low on-resistance, controlled charge injection, and predictable transition behavior help preserve signal fidelity.
Key features include a guaranteed maximum on-resistance of 100 ohm and operation in either signal direction. Improved versions also provide guaranteed channel matching of no more than 8 ohm and flatness of no more than 9 ohm over the specified signal range. The 4-bit address interface supports 16 channel selections, while the single-supply capability simplifies power architecture in systems that do not require dual-rail operation.
The DG406DN+ uses CMOS construction to provide low power use while maintaining short switching transitions. Its 15 pC charge-injection figure reduces the transient error produced when the address changes. Low on-resistance is particularly useful when routing higher-impedance sensors or low-amplitude signals because it minimizes voltage loss and improves input impedance. The 200 ns transition time supports faster measurement sequences than a slower mechanical or relay-based selector.
Typical uses include multiplexed sensor acquisition, automated test equipment, data acquisition, industrial control, signal routing, and communication systems. In each case, the DG406DN+ can consolidate multiple analog inputs onto a shared amplifier, converter, or processing channel. Designers must still evaluate signal amplitude, bandwidth, injected charge, and channel settling time for their specific source impedance and acquisition speed.
The primary design consideration is ensuring that the selected source impedance, acceptable settling interval, and allowable charge-injection error match the application. A low source resistance reduces settling error, while high source impedance can increase sensitivity to switch resistance and capacitance. Decoupling, grounding, and address-transition timing should be handled according to the manufacturer recommendations.
This page consolidates verified manufacturer and distributor information, package characteristics, pricing, drop-in candidates, and practical application guidance. It also distinguishes documented electrical facts from values that require confirmation, providing a practical engineering starting point without treating undocumented specifications as guaranteed.

Aplicações típicas
DG406DN+ é adequado para 6 aplicaçãos: Multiplexed Sensor Acquisition, Automated Test Equipment, Industrial Control Signal Routing, Data Acquisition Front End, Communication Line Monitoring, Precision Analog Signal Conditioning.
Multiplexed Sensor Acquisition
The DG406DN+ can connect 16 single-ended sensor inputs to one shared acquisition channel through its 4-bit binary address interface. Its 50 ohm typical on-resistance limits signal loss, while the 200 ns transition time supports reasonably fast channel selection. Designers should still calculate the RC settling error using the actual sensor impedance and acquisition sample rate. The 15 pC charge-injection value also matters for high-impedance sources because each address change can introduce a transient step into the selected signal.
Recomendado
Automated Test Equipment
A DG406DN+ based fixture can route 16 test points to a common measurement amplifier or converter, reducing the number of external signal paths. The 16:1 configuration and 100 ohm maximum on-resistance are useful for low-level test signals, while the 200 ns transition time supports rapid scan sequences. Address sequencing must leave sufficient settling time before each measurement, especially when the DUT presents high source impedance or when the instrument uses a narrow measurement aperture.
Recomendado
Industrial Control Signal Routing
DG406DN+ can consolidate 16 analog control or feedback signals onto a single controller-facing channel in an industrial control system. Its 50 ohm typical on-resistance provides low path resistance for moderate-impedance control signals, and its industrial temperature grade supports industrial-design requirements. The 44 V maximum supply rating provides useful headroom for protected industrial rails, although the engineer must verify the actual operating supply range and confirm that transient faults cannot exceed the device rating.
Recomendado
Data Acquisition Front End
The DG406DN+ is suitable for a multiplexed data-acquisition front end that needs to share one analog-to-digital conversion path across 16 inputs. The 4-bit address input produces 16 channel states, while the 200 ns transition time is short enough for many scan-rate requirements. Settling performance still depends on source capacitance, switch resistance, and the ADC acquisition window. The 15 pC charge-injection specification should be checked against the resolution and full-scale range of the selected converter.
Recomendado
Communication Line Monitoring
DG406DN+ can select among 16 monitored communication or network-related analog lines for subsequent comparison, measurement, or alarm processing. Bidirectional signal conduction allows the common path to be evaluated in either direction according to the manufacturer data. Because the maximum on-resistance is 100 ohm, line impedance and signal amplitude must be considered carefully. A long cable or high-impedance node can make the switch resistance more significant than the 50 ohm typical value suggests.
Recomendado
Precision Analog Signal Conditioning
For precision signal-conditioning systems, DG406DN+ provides a 16:1 routing function with 50 ohm typical on-resistance and improved versions specify channel matching up to 8 ohm and flatness up to 9 ohm. Matching and flatness help reduce errors when different channels are compared. The mux remains suitable only when its 15 pC charge injection and 200 ns transition time satisfy the required settling and acquisition window, particularly for high-impedance precision sources.

Notas de projeto
Treat channel settling as an RC-dependent measurement rather than relying only on the 200 ns transition-time figure. The 50 ohm typical on-resistance combines with source and parasitic capacitance to determine the time required before the selected signal is valid. For high-impedance sources, increase the address-to-sample delay and verify the resulting error against the converter resolution. Also evaluate the 15 pC charge injection because it creates a transient step at every address change.
Place the DG406DN+ close to the source and destination signal paths to minimize PCB capacitance and susceptibility to injected noise. Keep analog input routing away from high-current switching nodes and use a continuous ground reference around the 28-pin PLCC footprint. The verified material does not include a manufacturer reference layout, so exact via, fanout, and placement recommendations must be taken from the official DG406 datasheet package drawing and application guidance.
Do not assume that a matching PLCC package alone proves that every alternative is a drop-in replacement. Compare the numbered pin table, supply range, address-control polarity, on-resistance, charge injection, and transition timing before replacing DG406DN+. The 44 V value is a maximum supply rating, not a recommended operating voltage, and the verified excerpts do not provide a complete operating-voltage range. Confirm both limits in the manufacturer datasheet before applying the device to a new rail.
The listed 0.2 mW power figure supports low-power design, but the actual supply dissipation depends on the selected supply voltage and operating state. Provide local decoupling according to the manufacturer datasheet and keep the supply within the documented operating range. Because the verified data does not state quiescent current separately, do not derive it from the 0.2 mW figure without first confirming the operating condition used by Vishay.
Informações de conformidade
The verified excerpts discuss RoHS and REACH only in comparison-page snippets and do not provide an explicit compliance declaration for DG406DN+. Compliance fields are therefore left unknown. This interface IC is not presented as an AEC-Q100-qualified automotive device.
