Product details
Overview
DG406EWI 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 +5V to +30V single supply or ±4.5V to ±20V dual supplies and is used in precision data-acquisition systems requiring rail-to-rail signal handling and low leakage.
For engineers reviewing the DG406EWI datasheet, DG406EWI pinout, DG406EWI application, or DG406EWI 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 compatibility with TTL/CMOS logic controls.
Technical Context
The DG406EWI implements a CMOS transmission-gate architecture with bidirectional analog signal routing through a 4-bit binary address decoder (A0–A3) and active-low enable (EN). Its switch array supports rail-to-rail analog signals up to ±20V or +30V, with guaranteed performance across -40°C to +85°C.
Channel selection is deterministic and monotonic: EN = low enables switching; A3–A0 select one of 16 Sx inputs to connect to the common D terminal. Charge injection and on-resistance flatness are guaranteed by design-not just typical-ensuring consistent settling behavior in sample-and-hold and test equipment applications.
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 guarantees consistent gain scaling across multiplexed sensor inputs |
| Charge Injection | 15pC max limits voltage glitch on hold capacitors in sample-and-hold circuits |
| Analog Signal Range | ±10V (dual supply) or 0V to +10V (single supply) enables direct interfacing with industrial sensors |
| Input Leakage (T = +85°C) | <5nA max preserves accuracy in high-impedance transducer interfaces |
| ESD Protection | >2000V per MIL-STD 883 Method 3015.7 supports robust handling in manufacturing and field environments |
| Supply Range | +5V to +30V single or ±4.5V to ±20V dual allows flexible system-level power architecture integration |
Pinout & Package
DG406EWI is housed in a 28-pin wide SOIC (SO) package (package code W28+6), RoHS-compliant, with 0.300" body width and standard JEDEC MS-013 outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 28 | V+, D (DA) | V+ is positive supply rail; D is bidirectional common analog terminal for all 16 channels |
| 2, 27 | DB, V- | DB is second output (DG407 only); V- is negative supply rail - not connected in DG406EWI |
| 3, 13 | N.C. | No internal connection - must be left floating or grounded per layout best practice |
| 4–11 | S16–S9 | Bidirectional analog inputs (lower group), routed to D when selected |
| 12 | GND | Ground reference for logic and substrate; ties internal substrate to V+ per die topography |
| 14–17 | A3–A0 | 4-bit binary address inputs controlling channel selection (S1–S16) |
| 18 | EN | Active-low enable: EN = low enables switching; EN = high disconnects all channels |
| 19–26 | S1–S8 | Bidirectional analog inputs (upper group), routed to D when selected |
Key Features
| Feature | Design Value |
|---|---|
| Pin-compatible upgrade | Direct replacement for legacy DG406 with identical pinout and footprint - no PCB change required |
| Rail-to-rail signal handling | Supports analog signals from V- to V+ without clipping, enabling full dynamic range utilization |
| TTL/CMOS-compatible control | Accepts standard logic thresholds (VAL ≤ 0.8V, VAH ≥ 2.4V) - interoperable with microcontrollers and FPGAs |
| Guaranteed on-resistance flatness | 9Ω max variation across full analog signal range ensures linear gain response in instrumentation amplifiers |
| Low power consumption | 1.25mW max at +25°C reduces thermal drift and simplifies thermal management in dense layouts |
Applications
| Sample-and-Hold Circuits | Test Equipment |
|---|---|
Use Scenario: Capturing precise voltage levels from multiple sensors for ADC conversion with minimal hold-mode error. IC Role / Device Role / Timing Role: Analog multiplexer selecting input channel prior to sampling; low charge injection prevents hold capacitor disturbance.

IC Role / Device Role / Timing Role: High-fidelity signal path selector with guaranteed channel matching to avoid gain skew between test steps. Use Value: 8Ω max on-resistance matching ensures ≤0.01% gain error across 16 channels, critical for multi-point calibration traceability. |
| Guidance and Control Systems | Audio Signal Routing |
Use Scenario: Multiplexing feedback signals from inertial sensors (gyros, accelerometers) in aerospace flight controllers. IC Role / Device Role / Timing Role: Robust analog switch operating over -40°C to +85°C with ESD-hardened I/O for harsh avionics environments.

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, -40°C to +85°C, SOIC-28, but 25pC max charge injection | Higher charge injection limits use in high-resolution sample-and-hold; better for general-purpose routing | Select ADG406BRZ when lower on-resistance is prioritized over charge injection; verify hold-capacitor settling in target application |
| MAX4617ESE+ | 8-channel, 60Ω max on-resistance, +2.7V to +12V supply, SOIC-16, no dual-supply support | Half the channel count and narrower supply range - suitable for low-voltage embedded systems only | Choose MAX4617ESE+ for space-constrained, single-supply 8-channel designs where ± supplies are unavailable |
Compared with ADG406BRZ and MAX4617ESE+, the DG406EWI uniquely combines 16-channel count, dual-supply operation, guaranteed 15pC charge injection, and industrial temperature range in a drop-in SOIC-28 package - making it optimal for precision, high-channel-count data acquisition where signal integrity is non-negotiable.

FAQ
What is the maximum operating temperature range for the DG406EWI?
The DG406EWI is rated for operation from -40°C to +85°C. This extended industrial temperature range is confirmed in the Ordering Information table and supported by guaranteed leakage current (<5nA at +85°C) and on-resistance specifications across the full range. The "E" grade suffix explicitly denotes this temperature capability, distinguishing it from commercial-grade variants like DG406CWI+.
Does the DG406EWI support single-supply operation?
Yes, the DG406EWI supports single-supply operation from +5V to +30V. When using a single supply, V- must be connected to GND. The device maintains guaranteed on-resistance (100Ω max), charge injection (15pC max), and leakage performance under these conditions, as verified in the Electrical Characteristics tables for single-supply configurations.
Is the DG406EWI pin-compatible with older DG406 variants?
Yes, the DG406EWI is a pin-compatible plug-in upgrade for industry-standard DG406 devices. The pin configuration matches exactly across all 28 pins, including identical placement of V+, GND, D, S1–S16, A0–A3, EN, and N.C. terminals. This allows direct replacement without PCB modification, as explicitly stated in the General Description and Pin Configurations sections.
What is the analog signal range specification for DG406EWI under ±15V dual supply?
Under ±15V dual supply, the DG406EWI supports an analog signal range of ±10V (i.e., from -10V to +10V), referenced to V-. This is specified in the Electrical Characteristics table under "Analog Signal Range" with conditions V+ = +15V, V- = -15V. The range scales with supply voltage - e.g., ±20V supplies support ±15V signals.
How does the DG406EWI handle power-supply sequencing?
The DG406EWI requires proper sequencing: V+ must be applied first, then V-, followed by logic inputs and analog signals. Violating this sequence risks latch-up or damage. If sequencing cannot be guaranteed, external blocking diodes (as shown in Figure 1) should be added to V+ and V- pins - reducing analog range by ±1V but preserving all other electrical characteristics including on-resistance and leakage.
