Product details
Overview
DG406DN-E3 from Vishay Siliconix is a 16-channel single-ended CMOS analog multiplexer with TTL-compatible control inputs, 50 Ω on-resistance, 15 pC charge injection, and ±20 V dual-supply operation. It routes one of sixteen analog inputs to a common output under 4-bit binary address control and features break-before-make switching for input protection in data acquisition front ends.
For engineers reviewing the DG406DN-E3 datasheet, DG406DN-E3 pinout, DG406DN-E3 application, or DG406DN-E3 equivalent, this device is selected for high-accuracy, low-glitch signal routing in battery-powered instrumentation where rail-to-rail analog range, low leakage (<0.5 nA off-state), and fast transition time (200 ns typ.) are critical.
Technical Context
The DG406DN-E3 implements a silicon-gate CMOS architecture with epitaxial latchup protection and operates across ±5 V to ±20 V dual supplies or 12 V single supply. Its decoder/driver block interprets A0–A3 and EN inputs to activate exactly one of 16 bidirectional analog channels.
Each channel exhibits symmetrical conduction, 8 pF source-off capacitance, 130 pF drain-off capacitance, and -69 dB off-isolation at 100 kHz - enabling high-fidelity signal selection without crosstalk-induced measurement error in multi-sensor systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog configuration | 16:1 single-ended multiplexer - selects one input from 16 to common output |
| On-resistance (RDS(on)) | 50 Ω typical at ±15 V - ensures minimal signal attenuation and gain error in precision sensor interfaces |
| Charge injection | 15 pC typical - limits voltage glitch on sample-hold capacitors during channel switching |
| Transition time (tTRANS) | 200 ns typical - supports sampling rates up to ~694 kHz for 16-channel scanning at 12-bit accuracy |
| Supply voltage range | ±5 V to ±20 V dual or 12 V single - enables compatibility with industrial ±15 V rails and portable 12 V systems |
| Off-leakage current | 0.5 nA maximum at full temperature range - preserves signal integrity in high-impedance medical sensor paths |
| Enable function | Active-high EN pin - allows stacking multiple DG406DN-E3 devices with synchronized all-off reset |
Pinout & Package
DG406DN-E3 uses a 28-pin PLCC (Plastic Leaded Chip Carrier) package with 11.43 mm × 11.58 mm body, 1.27 mm lead pitch, and exposed thermal pad not electrically connected. Pin 1 is marked by corner notch; pins are numbered counterclockwise starting from top-left.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply rail | Accepts up to +44 V; defines upper analog signal limit and powers internal logic/switches |
| V- | Negative supply rail | Accepts down to -44 V; sets lower analog signal bound and enables true bipolar operation |
| GND | Ground reference | Logic ground and substrate reference; must be low-impedance to minimize noise coupling |
| D | Common analog output | Single bidirectional node connecting enabled channel to downstream ADC or amplifier |
| S1–S16 | Analog inputs | 16 independent bidirectional analog terminals; each blocks voltages beyond V+ and V- when off |
| A0–A3 | Binary address inputs | TTL-compatible 4-bit code selecting active channel (0–15); latched internally on rising edge of EN |
| EN | Enable control | Active-high logic input; disables all switches when low, preventing unintended channel conduction |
| NC | No-connect | Pins 4, 12, 13, 25 - internally unconnected; must remain floating or grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guarantees >50 ns isolation between channel disconnect and next connect - prevents momentary input shorting |
| Rail-to-rail analog range | Full swing from V− to V+ - supports ±10 V sensor signals without clipping in ±15 V systems |
| Low power dissipation | 0.2 mW typical quiescent - reduces self-heating and thermal drift in sealed medical enclosures |
| 44 V absolute max rating | Withstands transient overvoltage up to ±44 V - enhances robustness in industrial ESD-prone environments |
| TTL-compatible inputs | Valid logic levels at 0.8 V (low) and 2.4 V (high) across −40 °C to +85 °C - eliminates level-shifter need |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG406BRZ | 44 V abs max rating same; RDS(on) = 75 Ω typ. at ±15 V; 20 pC charge injection | Higher on-resistance increases gain error in precision DC measurements; higher charge injection degrades settling in fast S/H circuits | Select ADG406BRZ only if footprint compatibility with SOIC-28 is required and 25 Ω higher RDS(on) is acceptable |
| MAX4617CWI+ | 16-channel but 100 Ω RDS(on) typ.; 30 pC charge injection; max ±16.5 V supply | Lower voltage rating excludes use in ±20 V industrial systems; higher leakage (5 nA max) limits medical-grade accuracy | Choose MAX4617CWI+ only for cost-sensitive 12 V single-supply designs where 100 Ω on-resistance suffices |
Compared with ADG406BRZ and MAX4617CWI+, the DG406DN-E3 delivers superior analog performance via lower on-resistance, lower charge injection, and wider supply range - making it optimal for high-accuracy, wide-dynamic-range multiplexing where signal integrity is non-negotiable.

FAQ
What is the maximum supply voltage rating for DG406DN-E3?
The DG406DN-E3 has an absolute maximum supply rating of ±44 V referenced to V−, allowing safe operation with ±20 V dual supplies or 12 V single supply. This 44 V rating provides margin against transients in industrial environments and enables compatibility with standard ±15 V and ±12 V system rails. Operation outside these limits risks permanent damage.
Does DG406DN-E3 support single-supply operation?
Yes, DG406DN-E3 supports single-supply operation with V− tied to GND and V+ at 12 V. In this configuration, the analog signal range is 0 V to 12 V, RDS(on) rises to 90 Ω typical, and dynamic parameters such as tTRANS and charge injection remain within specification. The device retains TTL-compatible control inputs and break-before-make functionality.
How does the enable (EN) pin function in DG406DN-E3?
The EN pin on DG406DN-E3 is an active-high digital control that globally disables all 16 analog switches when low. When EN = 0 V, no channel conducts regardless of A0–A3 state - enabling safe stacking of multiple DG406DN-E3 devices in large-scale multiplexers. When EN = 2.4 V min, channel selection resumes based on the A0–A3 address.
What is the significance of break-before-make timing in DG406DN-E3?
Break-before-make timing in DG406DN-E3 guarantees a minimum 50 ns interval between deactivation of one channel and activation of the next. This prevents momentary shorting of two analog inputs - critical when multiplexing sensors with different output impedances or voltage levels. The feature is inherent to the internal decoder timing and requires no external circuitry.
Can DG406DN-E3 be used in medical-grade ECG front ends?
Yes, DG406DN-E3 is suitable for ECG front ends due to its <0.5 nA maximum off-leakage current, 15 pC charge injection, and low 8 pF source-off capacitance - all minimizing baseline shift and noise coupling during electrode switching. Its ±20 V supply capability supports defibrillator-safe isolation stages, and the PLCC package offers reliable long-term solder joint integrity.
