Product details
Overview
DG406DN from Maxim Integrated is a 16-channel single-ended CMOS analog multiplexer with guaranteed 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 +4.5V to +30V single supply and is used in precision data-acquisition systems requiring rail-to-rail signal handling and low leakage.
For engineers reviewing the DG406DN datasheet, DG406DN pinout, DG406DN application, or DG406DN equivalent, key selection criteria include on-resistance flatness (9Ω max), input off-leakage (<5nA at +85°C), ESD protection (>2000V), TTL/CMOS-compatible digital control, and PLCC-28 packaging for industrial temperature operation (-40°C to +85°C).
Technical Context
The DG406DN implements a CMOS transmission-gate architecture with integrated address decoding (A0–A3) and enable-controlled switching. Its bidirectional analog path supports rail-to-rail signal ranges up to ±15V with guaranteed monotonic on-resistance versus voltage and temperature.
It features break-before-make timing (130–300ns), fast enable-controlled switching (tON(EN) = 105–600ns), and low dynamic parameters including 8pF logic input capacitance and 70pF drain-source on-capacitance - critical for high-fidelity audio routing and sample-and-hold accuracy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 100Ω max ensures minimal signal attenuation and gain error in precision measurement paths |
| On-resistance matching | 8Ω max between channels enables accurate multi-channel ratiometric measurements |
| Charge injection | 15pC max limits voltage glitch and settling error in sample-and-hold circuits |
| Analog signal range | ±10V (dual supply) or 0–12V (single supply) supports full-rail operation without clipping |
| Input leakage (T = +85°C) | <5nA max preserves high-impedance sensor interface integrity over temperature |
| ESD protection | >2000V per MIL-STD-883 Method 3015.7 reduces board-level ESD hardening requirements |
| Supply range | ±4.5V to ±20V dual or +4.5V to +30V single allows flexible system power architecture |
Pinout & Package
DG406DN is housed in a 28-lead PLCC (Plastic Leaded Chip Carrier) package with gull-wing leads, rated for -40°C to +85°C operation and optimized for reflow soldering and high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D | Bidirectional analog common terminal | Single output path shared across all 16 channels; must be routed with controlled impedance for signal integrity |
| S1–S16 | Bidirectional analog channel inputs | 16 independent analog inputs; S1–S8 occupy pins 19–26, S9–S16 occupy pins 4–11 |
| A0–A3 | Binary address inputs | Selects active channel (0–15); logic thresholds TTL/CMOS compatible (VAL ≤ 0.8V, VAH ≥ 2.4V) |
| EN | Active-low enable input | Disables all switches when high; enables decoding and conduction when low |
| V+ | Positive supply rail | Accepts +4.5V to +30V (single) or +4.5V to +20V (dual); substrate tied internally |
| V- | Negative supply rail | Accepts –4.5V to –20V (dual); required for bipolar signal handling |
| GND | Reference ground | Signal reference point; separate from power return in mixed-signal layouts |
| N.C. | No internal connection | Pins 2, 3, 13 are unconnected; must remain floating or grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| PIN-COMPATIBLE UPGRADE | Direct replacement for legacy DG406 with identical PLCC-28 pinout and function - no PCB redesign needed |
| Rail-to-rail signal handling | Supports analog signals from V– to V+ without distortion, enabling full dynamic range utilization in ±15V systems |
| Guaranteed on-resistance flatness | 9Ω max variation across full signal range minimizes harmonic distortion in audio routing applications |
| Low power consumption | 1.25mW max total supply power simplifies thermal management in dense instrumentation modules |
| Digital input compatibility | TTL/CMOS logic thresholds eliminate need for level-shifting circuitry in microcontroller interfaces |

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 on-resistance, but only specified for –40°C to +85°C with 28-SOIC package | Lacks PLCC-28 footprint; requires PCB redesign; lower on-resistance benefits low-voltage systems | Choose ADG406BRZ only if SOIC layout is acceptable and sub-75Ω RON is prioritized over mechanical compatibility |
| MAX4617CSE+ | 16-channel, 60Ω max on-resistance, but limited to +12V single-supply operation and 16-pin QSOP | Not pin-compatible; no dual-supply support; unsuitable for ±15V signal chains | Select MAX4617CSE+ only for cost-sensitive, low-voltage DC-coupled applications where supply flexibility is not required |
Compared with DG406DN, ADG406BRZ offers lower on-resistance but mandates SOIC layout change and lacks PLCC mechanical compatibility, while MAX4617CSE+ sacrifices dual-supply operation and channel count for reduced package size - making DG406DN the sole option supporting industrial-temperature PLCC-28 deployment with full ±20V bipolar capability.

FAQ
What is the maximum allowable supply voltage for DG406DN?
The DG406DN supports dual supplies from ±4.5V to ±20V and single supplies from +4.5V to +30V. Absolute maximum ratings specify V+ to V− differential up to +44V, and V+ referenced to V− must not exceed –0.3V to +44V. Exceeding these limits risks permanent damage, per MIL-STD-883 stress guidelines.
Does DG406DN support rail-to-rail analog signal operation?
Yes, DG406DN supports rail-to-rail analog signal handling - signals can swing from V− to V+ without clipping or distortion. This is confirmed in the Electrical Characteristics table where VANALOG is specified as ±10V (dual supply) and 0–12V (single supply), and reinforced by functional diagrams showing direct connection to V+ and V− rails.
What is the pin configuration of DG406DN and how does it differ from other DG406 variants?
DG406DN uses a 28-lead PLCC package with pin assignments matching the standard DG406 pinout: D (pin 28), V− (27), S8–S1 (26–19), EN (18), A0–A2 (17–15), V+ (1), GND (12), S16–S9 (11–4), and N.C. (2, 3, 13). Unlike DG406DJ (DIP) or DG406DWI (SO), DG406DN's PLCC footprint provides superior thermal dissipation and board-area efficiency for industrial PCBs.
Is DG406DN pin-compatible with the original industry-standard DG406?
Yes, DG406DN is explicitly documented as a pin-compatible plug-in upgrade for the industry-standard DG406. The datasheet states "These improved muxes are pin-compatible plug-in upgrades" and confirms identical pin functions and ordering codes (e.g., DG406DN vs. DG406DJ), ensuring drop-in replacement without layout modification.
What is the guaranteed charge injection specification for DG406DN and why does it matter?
DG406DN guarantees ≤15pC maximum charge injection, measured under specified conditions (CL = 1.0nF, VS = 0V, RS = 0Ω). This parameter directly impacts sample-and-hold accuracy: lower charge injection reduces voltage glitch and settling time errors, enabling faster acquisition cycles and higher effective resolution in precision ADC front-ends.
