Product details
Overview
DG406DN+ from Maxim Integrated is a 16-channel single-ended CMOS analog multiplexer with rail-to-rail signal handling, 100Ω max on-resistance, 8Ω max channel-to-channel on-resistance matching, and 15pC max charge injection. It operates from ±4.5V to ±20V dual supplies or +5V to +30V single supply and is used in precision data-acquisition systems requiring low leakage and high channel uniformity.
For engineers reviewing the DG406DN+ datasheet, DG406DN+ pinout, DG406DN+ application, or DG406DN+ equivalent, key selection criteria include guaranteed on-resistance flatness (9Ω max), input off-leakage <5nA at +85°C, ESD protection >2000V per MIL-STD 883 Method 3015.7, and PLCC-28 packaging for industrial temperature operation (-40°C to +85°C).
Technical Context
The DG406DN+ implements a CMOS transmission-gate architecture with TTL/CMOS-compatible digital control inputs (A0–A3, EN) and bidirectional analog signal paths. Its internal decoder drives 16 independent analog switches between common D and individual S1–S16 terminals.
It guarantees monotonic on-resistance behavior across the full analog signal range (±15V dual supply), supports unbalanced supplies (e.g., +24V/–5V), and maintains rail-to-rail conduction without signal clipping-enabling direct interfacing with op-amps and ADCs in mixed-signal front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RDS(ON)) | 100Ω max - ensures minimal voltage drop and gain error in precision signal routing |
| On-Resistance Matching | 8Ω max - enables accurate differential measurements and channel calibration |
| On-Resistance Flatness | 9Ω max - preserves linearity over full ±15V analog input range |
| Charge Injection | 15pC max - reduces sampling error in sample-and-hold and switched-capacitor circuits |
| Input Off-Leakage Current | <5nA at +85°C - maintains high-impedance integrity in high-resolution data acquisition |
| ESD Protection | >2000V per MIL-STD 883 Method 3015.7 - supports robust handling in manufacturing and field environments |
| Supply Range | ±4.5V to ±20V dual or +5V to +30V single - allows flexible system-level power architecture integration |
Pinout & Package
DG406DN+ is housed in a 28-lead PLCC (Plastic Leaded Chip Carrier) package with gull-wing leads, RoHS-compliant, rated for –40°C to +85°C operation. The package provides mechanical stability and thermal performance suitable for industrial PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | V+ | Positive supply rail - must be powered before V– and logic inputs to prevent latch-up |
| 2 | DA (D) | Bidirectional common analog terminal - connects to ADC input, DAC output, or instrumentation amplifier |
| 4–11 | S16–S9 | Analog channel inputs - routed to DA when selected; high-impedance when off |
| 12 | GND | Ground reference - shared with digital logic and analog return path |
| 14–17 | A3–A0 | Binary address inputs - select one of 16 channels (0000 to 1111) |
| 18 | EN | Enable control - high-active; disables all switches when low |
| 19–26 | S1–S8 | Analog channel inputs - lower-numbered channels; identical electrical behavior to S9–S16 |
| 27 | V− | Negative supply rail - required for bipolar operation; ties to GND for single-supply use |
| 2, 3, 13 | N.C. | No internal connection - must remain unconnected on PCB |
Key Features
| Feature | Design Value |
|---|---|
| PIN-COMPATIBLE UPGRADE | Direct replacement for legacy DG406 - no PCB redesign required for performance enhancement |
| Rail-to-Rail Signal Handling | Supports analog signals from V− to V+ - eliminates level-shifting circuitry in wide-dynamic-range systems |
| TTL/CMOS-Compatible Inputs | Accepts standard logic thresholds (VAL ≤ 0.8V, VAH ≥ 2.4V) - interoperable with microcontrollers and FPGAs |
| Low Power Consumption | 1.25mW max - enables use in battery-powered test equipment and portable instrumentation |
| Guaranteed Channel Matching | 8Ω max RDS(ON) mismatch - critical for ratiometric measurements and multi-channel calibration |
Applications
| Sample-and-Hold Circuits | Test Equipment |
|---|---|
Use Scenario: Sampling multiple sensor outputs into a single ADC using hold capacitors. IC Role / Device Role / Timing Role: Analog switch selecting input channel during acquisition phase; low charge injection prevents hold-step error.

IC Role / Device Role / Timing Role: High-fidelity signal path selector enabling programmable test configurations without relay wear-out. Use Value: 100Ω max on-resistance and 9Ω flatness ensure consistent insertion loss across all 16 channels, improving test repeatability. |
| Guidance and Control Systems | Data-Acquisition Systems |
Use Scenario: Multiplexing feedback signals from inertial sensors, gyros, and accelerometers in avionics subsystems. IC Role / Device Role / Timing Role: Fault-tolerant analog interface providing redundant signal routing with guaranteed leakage <5nA at +85°C.

IC Role / Device Role / Timing Role: Precision front-end switch enabling sequential scanning with matched channel gain and offset. Use Value: 8Ω max on-resistance matching allows software-based channel-to-channel correction, reducing calibration overhead. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG406BRZ | 16-channel, 75Ω max RDS(ON), –40°C to +85°C, SOIC-28; lower on-resistance but higher charge injection (25pC) | Better for low-distortion audio routing; less suitable for precision sample-and-hold where charge injection dominates error | Select ADG406BRZ when on-resistance is primary constraint and temperature range matches; verify charge injection impact in hold-phase timing. |
| MAX4617CSE+ | 16-channel, 60Ω max RDS(ON), 0°C to +70°C, SOIC-16; smaller package, narrower temp range, no PLCC option | Targeted at commercial-grade instrumentation; lacks industrial temp rating and PLCC mechanical robustness | Choose MAX4617CSE+ only for cost-sensitive, non-industrial designs where 0°C to +70°C suffices and board space is constrained. |
Compared with ADG406BRZ and MAX4617CSE+, DG406DN+ delivers superior channel matching (8Ω vs. 15Ω/20Ω typical), guaranteed flatness over full signal range, and PLCC packaging optimized for thermal cycling reliability-making it preferred for aerospace, industrial DAQ, and high-accuracy test systems.

FAQ
What is the operating temperature range for DG406DN+?
The DG406DN+ is rated for operation from –40°C to +85°C. This industrial temperature range is validated per the device's qualification testing and supported by guaranteed electrical specifications-including leakage current <5nA at +85°C and on-resistance flatness-across the full range. The PLCC package contributes to thermal reliability in sustained high-temperature environments.
Does DG406DN+ support single-supply operation?
Yes, DG406DN+ supports +5V to +30V single-supply operation. In this configuration, V– must be connected to GND. The device maintains rail-to-rail analog signal handling (0V to V+) and retains all key specs including 100Ω max on-resistance and 15pC max charge injection. Switching times increase at lower voltages (e.g., 5V), as noted in the datasheet timing characteristics.
Is DG406DN+ pin-compatible with the original DG406?
Yes, DG406DN+ is a pin-compatible plug-in upgrade for the industry-standard DG406. All 28 pins-including V+, V–, GND, A0–A3, EN, D, and S1–S16-match the legacy DG406 footprint and function. No PCB layout changes are needed; the upgrade delivers improved matching (8Ω vs. unspecified legacy), flatness (9Ω), and leakage performance without design modification.
What is the maximum analog signal range supported by DG406DN+?
DG406DN+ supports an analog signal range from V– to V+, up to ±20V with dual supplies or 0V to +30V with single supply. At ±15V dual supply, the guaranteed analog range is ±15V. Operation outside these limits risks exceeding absolute maximum ratings and may cause permanent damage. Signal range scales linearly with supply voltage magnitude.
How does DG406DN+ handle power-supply sequencing?
DG406DN+ requires proper sequencing: V+ must be applied first, then V–, followed by logic inputs and analog signals. Violating this order risks latch-up or ESD damage. If sequencing cannot be guaranteed, external blocking diodes (as shown in Figure 1 of the datasheet) should be added-reducing usable analog range by ~1V but preserving low-leakage and low-RON performance.
