Product details
Overview
DG406DJ from Maxim Integrated is a 16-channel single-ended CMOS analog multiplexer/demultiplexer designed for precision signal routing in data-acquisition and test systems. It features guaranteed on-resistance matching ≤8Ω, flatness ≤9Ω, low charge injection ≤15pC, max on-resistance of 100Ω, and operates across -40°C to +85°C with ±4.5V to ±20V dual or +5V to +30V single supply.
For engineers reviewing the DG406DJ datasheet, DG406DJ pinout, DG406DJ application, or DG406DJ equivalent, key selection criteria include channel-to-channel resistance matching, rail-to-rail analog signal handling (±10V typical), TTL/CMOS-compatible digital control, ESD robustness (>2000V), and leakage performance (<5nA at +85°C) in industrial-temperature plastic DIP packaging.
Technical Context
The DG406DJ implements a CMOS transmission-gate architecture with decoder-driven address selection (A0–A3) and active-low enable (EN), supporting bidirectional analog signal flow between common output D and any of 16 source terminals S1–S16. Its internal switch design guarantees monotonic on-resistance variation over the full analog signal range (±10V) and temperature (-40°C to +85°C).
Operation requires strict power-supply sequencing (V+ first, then V-, then logic inputs) to avoid latch-up; unbalanced supplies (e.g., +24V/–5V) are supported. Analog signal range is rail-to-rail, bounded by V+ and V–, and input protection diodes clamp signals exceeding supply rails-forward current must be limited to 30mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RDS(ON)) | 100Ω max - ensures minimal signal attenuation and voltage drop in precision analog paths |
| On-Resistance Matching | 8Ω max - enables high-accuracy differential measurements and channel calibration |
| On-Resistance Flatness | 9Ω max - maintains consistent gain and linearity across full ±10V signal swing |
| Charge Injection | 15pC max - reduces settling error and droop in sample-and-hold circuits |
| Input Off-Leakage Current | 5nA max at +85°C - preserves accuracy in high-impedance sensor interfaces and integrators |
| Supply Range | +5V to +30V single or ±4.5V to ±20V dual - supports wide-range industrial and test equipment rails |
| ESD Protection | >2000V per MIL-STD-883 Method 3015.7 - enhances reliability in handling and board-level environments |
Pinout & Package
DG406DJ is supplied in a 28-pin plastic DIP package (0.600" width), RoHS-compliant (denoted by '+' suffix), rated for -40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | V+ | Positive supply rail - must be powered before V– and logic inputs to prevent latch-up |
| 2 | N.C. | No internal connection - left floating; no PCB trace required |
| 3 | N.C. | No internal connection - left floating; no PCB trace required |
| 4–11 | S16–S9 | Bidirectional analog inputs - selectable as signal sources or sinks under address control |
| 12 | GND | Ground reference - serves as return path for logic and substrate bias |
| 13 | N.C. | No internal connection - left floating; no PCB trace required |
| 14–17 | A3–A0 | Binary address inputs - select one of 16 channels (S1–S16) when EN = low |
| 18 | EN | Active-low enable - disables all switches when high; must be ≤0.8V for channel activation |
| 19–26 | S1–S8 | Bidirectional analog inputs - complementary set to S9–S16 for full 16-channel coverage |
| 27 | V- | Negative supply rail - powers analog core; sequencing after V+ prevents damage |
| 28 | D | Common bidirectional analog terminal - connects to selected Sx channel; handles rail-to-rail signals |
Key Features
| Feature | Design Value |
|---|---|
| PIN-COMPATIBLE UPGRADE | Direct replacement for legacy DG406 - no PCB redesign needed for improved specs |
| Rail-to-Rail Signal Handling | Supports analog signals from V– to V+, enabling full utilization of supply headroom in ±15V or +12V systems |
| TTL/CMOS-Compatible Control | Accepts standard logic thresholds (VAL ≤0.8V, VAH ≥2.4V) without level-shifting circuitry |
| Guaranteed Low Leakage | Input off-leakage <5nA at +85°C - critical for integrating amplifiers and high-Z sensor front-ends |
| Low Power Consumption | 1.25mW max - reduces thermal drift and simplifies thermal management in dense layouts |

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, 28-lead SOIC; RDS(ON) = 75Ω typ, 100Ω max; charge injection = 25pC typ | Higher typical on-resistance flatness (15Ω) and higher charge injection reduce precision in sample-and-hold use | Preferred where SOIC footprint and slightly lower RDS(ON) outweigh need for lowest charge injection |
| MAX4617CPE+ | 16-channel, 28-pin PDIP; RDS(ON) = 125Ω max; leakage = 10nA at +85°C; no guaranteed matching spec | Lacks guaranteed channel matching and flatness specs - unsuitable for calibrated multichannel systems | Acceptable for cost-sensitive general-purpose routing where matching is not critical |
Compared with ADG406BRZ and MAX4617CPE+, the DG406DJ delivers superior channel matching (≤8Ω) and lower charge injection (≤15pC), making it optimal for precision data-acquisition and metrology-grade applications where signal integrity across all 16 channels must be tightly controlled.

FAQ
What is the operating temperature range of the DG406DJ?
The DG406DJ is rated for operation from -40°C to +85°C. This industrial temperature grade is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the datasheet. The device maintains guaranteed performance-including on-resistance matching, leakage, and charge injection-across this full range, making it suitable for harsh-environment applications where ambient temperatures exceed commercial-grade limits.
Is the DG406DJ pin-compatible with older DG406 variants?
Yes, the DG406DJ is explicitly described as a "pin-compatible plug-in upgrade" for industry-standard DG406 devices. Its 28-pin DIP footprint, pin functions (V+, V-, GND, D, S1–S16, A0–A3, EN), and electrical interface match legacy versions. No PCB layout changes are required-only firmware or system-level validation of improved parameters (e.g., lower leakage, tighter matching) is needed for migration.
What supply voltage configurations does the DG406DJ support?
The DG406DJ supports both single-supply (+5V to +30V, with V– tied to GND) and dual-supply (±4.5V to ±20V) operation. It also tolerates unbalanced supplies such as +24V/–5V. The analog signal range extends rail-to-rail (V– to V+), and proper sequencing-V+ first, then V–, then logic inputs-is required to prevent latch-up, as specified in the Applications Information section.
How does the DG406DJ handle charge injection in sample-and-hold circuits?
The DG406DJ guarantees ≤15pC maximum charge injection, a critical parameter for minimizing voltage step errors during switch turn-off in sample-and-hold stages. This value is tested and specified across temperature and supply conditions. When paired with a 1nF hold capacitor (as in Figure 5 of the datasheet), the resulting voltage glitch is ≤15mV-enabling sub-12-bit accuracy without additional correction circuitry.
Does the DG406DJ require external protection diodes for overvoltage tolerance?
No-internal clamping diodes protect digital and analog pins against signals exceeding V+ or V–, but forward current must be externally limited to ≤30mA. For operation beyond absolute maximum ratings (e.g., transient surges), external series diodes may be added per Figure 1, reducing usable analog range by ~1V but preserving low-leakage and low-RON performance. The DG406DJ itself does not require them for normal compliant operation.
