Product details
Overview
DG406DN+T 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-designed for precision data-acquisition systems requiring low distortion and high channel consistency.
For engineers reviewing the DG406DN+T datasheet, DG406DN+T pinout, DG406DN+T application, or DG406DN+T equivalent, key selection criteria include guaranteed on-resistance flatness (9Ω max), -40°C to +85°C operating range, PLCC-28 package compatibility, and dual-supply (±4.5V to ±20V) or single-supply (+5V to +30V) operation.
Technical Context
The DG406DN+T implements a CMOS transmission-gate architecture with TTL/CMOS-compatible digital control inputs (A0–A3, EN) and bidirectional analog signal paths between S1–S16 and D terminals. It features internal substrate biasing tied to V+, enabling robust rail-to-rail analog conduction without level-shifting circuitry.
Its switching performance is characterized by 400ns max enable turn-on time (tON(EN)), 300ns max enable turn-off time (tOFF(EN)), and 400ns max transition time (tTRANS) under ±15V dual-supply conditions-optimized for sample-and-hold and test-equipment applications demanding fast, low-glitch channel selection.
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 - guarantees consistent gain across all 16 channels in multi-channel measurement systems |
| On-Resistance Flatness | 9Ω max - maintains stable impedance over full ±10V analog signal range, reducing harmonic distortion |
| Charge Injection | 15pC max - limits sampling error in high-impedance sample-and-hold circuits |
| Analog Signal Range | ±10V - supports rail-to-rail operation with ±15V supplies, enabling full dynamic range utilization |
| Supply Range | +5V to +30V single or ±4.5V to ±20V dual - allows flexible power architecture in industrial and test equipment |
| ESD Protection | >2000V per MIL-STD-883 Method 3015.7 - enhances reliability in handling and board-level integration |
Pinout & Package
DG406DN+T is housed in a 28-lead PLCC (Plastic Leaded Chip Carrier) package with gull-wing leads, RoHS-compliant and lead-free. The package provides mechanical robustness and thermal performance suitable for industrial temperature operation (-40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | V+ | Positive supply input - must be powered before V- and logic inputs to prevent latch-up |
| 2, 3, 13 | N.C. | No internal connection - must remain unconnected on PCB |
| 4–11 | S16–S9 | Bidirectional analog inputs - selected channel connects to D terminal when enabled |
| 12 | GND | Ground reference - common return for analog and digital sections |
| 14–17 | A3–A0 | Binary address inputs - select one of 16 channels (0000–1111) in conjunction with EN |
| 18 | EN | Enable input - active-low; disables all switches when high (logic '1') |
| 19–26 | S1–S8 | Bidirectional analog inputs - lower half of 16-channel array |
| 27 | V- | Negative supply input - required for dual-supply operation; tied to GND for single-supply use |
| 28 | D | Bidirectional analog output/common terminal - connects to selected Sx channel when EN = low |
Key Features
| Feature | Design Value |
|---|---|
| PIN-COMPATIBLE UPGRADE | Direct replacement for legacy DG406 - no PCB layout change required for drop-in performance enhancement |
| LOW CHARGE INJECTION | 15pC max - reduces settling error in high-resolution ADC front-ends and sample-and-hold amplifiers |
| Rail-to-Rail Signal Handling | Supports analog signals from V- to V+ - eliminates need for external level shifters in wide-dynamic-range systems |
| TTL/CMOS-Compatible Control | Logic thresholds at 0.8V (low) and 2.4V (high) - interoperable with standard microcontrollers and FPGAs without interface buffers |
| Low Input Off-Leakage | <5nA at +85°C - preserves accuracy in high-impedance sensor multiplexing (e.g., thermocouples, pH electrodes) |

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 RON, but only 25pC max charge injection and no guaranteed matching spec | Higher on-resistance variation impacts multi-channel gain matching; less suitable for precision metrology | Prefer DG406DN+T where channel uniformity and low charge injection are mandatory |
| MAX4617CSE+ | 8-channel, 60Ω max RON, 10pC max charge injection, SO-16 package - not pin-compatible | Limited to 8 channels; requires PCB redesign; better for space-constrained, lower-channel-count designs | Select DG406DN+T when 16-channel count, PLCC-28 footprint, and industrial temp range are required |
Compared with ADG406BRZ and MAX4617CSE+, the DG406DN+T uniquely delivers 16-channel count, guaranteed 8Ω matching, and -40°C to +85°C operation in PLCC-28-making it optimal for industrial data loggers and automated test equipment where channel consistency and rugged packaging are non-negotiable.

FAQ
What is the maximum allowable supply voltage for DG406DN+T?
The DG406DN+T supports absolute maximum ratings of V+ up to +44V referenced to V-, and continuous analog signal range up to ±20V with appropriate supply rails. For reliable operation, use within the recommended dual-supply range of ±4.5V to ±20V or single-supply range of +5V to +30V. Exceeding these may cause permanent damage per Absolute Maximum Ratings table.
Does DG406DN+T support single-supply operation?
Yes, DG406DN+T supports single-supply operation from +5V to +30V. In this mode, connect V- to GND. The analog signal range becomes 0V to V+, enabling rail-to-rail conduction. Performance parameters-including on-resistance and charge injection-are fully specified under both single- and dual-supply conditions in the datasheet.
What is the function of the EN pin on DG406DN+T?
The EN (Enable) pin on DG406DN+T is an active-low digital control input. When EN is logic low (≤0.8V), the selected channel (determined by A3–A0) connects Sx to D. When EN is logic high (≥2.4V), all switches are disabled and high-impedance. This enables global channel enable/disable independent of address lines, simplifying system-level power gating.
Is DG406DN+T pin-compatible with older DG406 variants?
Yes, DG406DN+T is a pin-compatible plug-in upgrade for industry-standard DG406 devices, including DG406CJ+, DG406DJ+, and DG406AK. It retains identical PLCC-28 pinout, electrical interface, and functional behavior while improving key specs: guaranteed 8Ω channel matching, 9Ω on-resistance flatness, and 15pC max charge injection.
What does "N.C." mean for pins 2, 3, and 13 on DG406DN+T?
"N.C." stands for No Connection - these pins (2, 3, and 13) have no internal connection to the die and must remain unconnected on the PCB. Soldering or routing traces to them may cause parasitic coupling or mechanical stress. The DG406DN+T datasheet explicitly states N.C. = NO INTERNAL CONNECTION, and they serve no electrical or thermal function.
