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 ±4.5V to ±20V dual supplies or +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 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, TTL/CMOS-compatible digital control, and ESD protection >2000V per MIL-STD 883 Method 3015.7.
Technical Context
The DG406EWI+ implements a CMOS transmission-gate architecture with bidirectional analog signal routing through a 4-bit binary decoder (A0–A3) and enable-controlled switching. Its rail-to-rail operation supports full-swing analog signals up to ±20V or 0V to +30V, with guaranteed performance across -40°C to +85°C.
Channel selection is synchronous and non-latching; all address inputs (A0–A3) and EN must be stable before switching. The device features internal clamping diodes on all analog and digital pins, enabling overvoltage tolerance when external protection diodes are added per Figure 1 in the datasheet.
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 - guarantees consistent gain and offset across all 16 channels for multi-channel calibration |
| On-Resistance Flatness | 9Ω max - maintains linearity over full analog signal range (±10V typical), critical for sample-and-hold accuracy |
| Charge Injection | 15pC max - limits voltage glitch on hold capacitors, enabling sub-12-bit settling in data-acquisition systems |
| Input Off-Leakage | <5nA at +85°C - preserves high-impedance sensor node integrity and long hold times |
| Supply Range | ±4.5V to ±20V dual or +5V to +30V single - supports industrial, test, and avionics power architectures |
| ESD Protection | >2000V HBM - meets MIL-STD-883 Method 3015.7 for robust handling in manufacturing and field environments |
Pinout & Package
DG406EWI+ is housed in a 28-pin Wide SO (SOIC-W) RoHS-compliant package, 17.9mm × 7.6mm body size, with standard 1.27mm pitch and exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 28 | V+, D (DA) | V+ = positive supply input; D = bidirectional analog common terminal (output in mux mode, input in demux mode) |
| 2, 27 | DB, V- | DB = second output (DG407 only); V- = negative supply input - unused in single-supply operation |
| 3, 13, 14 | N.C. | No internal connection - must remain unconnected; floating or tied to GND has no effect |
| 4–11 | S16–S9 | Bidirectional analog inputs/outputs - channels 9–16 of 16-channel switch array |
| 12 | GND | Analog/digital ground reference - requires low-impedance connection to system ground plane |
| 15–17 | A2, A1, A0 | Address inputs - LSBs of 4-bit binary channel select code (A3 on pin 18) |
| 18 | EN | Enable input - active-low logic control; EN = low enables switching, high disables all channels |
| 19–26 | S1–S8 | Bidirectional analog inputs/outputs - channels 1–8 of 16-channel switch array |
| 27 | V- | Negative supply input - required for dual-supply operation; connect to GND for single-supply use |
Key Features
| Feature | Design Value |
|---|---|
| PIN-COMPATIBLE UPGRADE | Direct replacement for legacy DG406 - same pinout, footprint, and timing, enabling drop-in reliability improvement without PCB change |
| Rail-to-Rail Signal Handling | Supports analog signals from V− to V+ - eliminates level-shifting circuitry in ±15V or 0–24V systems |
| TTL/CMOS-Compatible Inputs | Logic thresholds (VAL ≤ 0.8V, VAH ≥ 2.4V) interface directly with microcontrollers and FPGAs without level translators |
| Low Power Consumption | 1.25mW max at +25°C - reduces thermal drift and simplifies thermal management in dense layouts |
| Guaranteed Dynamic Performance | tON(EN) ≤ 400ns, tTRANS ≤ 400ns - enables high-throughput scanning in automated test equipment |

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 rated for -40°C to +85°C with 100pC charge injection (vs. 15pC) | Higher charge injection limits use in precision sample-and-hold; lower RON benefits low-voltage signal paths | Select ADG406BRZ only when lower on-resistance outweighs charge injection sensitivity |
| TS5A3154DCUR | Single 4-channel, 0.9Ω RON, but limited to 5.5V supply and 100nA leakage at +85°C | Not scalable to 16-channel; unsuitable for ±15V industrial or aerospace signal ranges | Choose TS5A3154DCUR only for low-voltage, high-speed consumer audio routing where supply headroom is constrained |
Compared with ADG406BRZ and TS5A3154DCUR, DG406EWI+ uniquely balances wide supply range (+5V to +30V / ±4.5V to ±20V), ultra-low charge injection (15pC), and guaranteed -40°C to +85°C operation - making it the only option qualified for high-precision, wide-temperature, multi-channel industrial data acquisition.

FAQ
What is the operating temperature range for DG406EWI+?
DG406EWI+ is specified for operation from -40°C to +85°C. This extended industrial temperature range is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the datasheet. All electrical characteristics-including on-resistance matching, charge injection, and leakage-are guaranteed across this full range. The "E" prefix in DG406EWI+ explicitly denotes the -40°C to +85°C grade, distinguishing it from commercial (C) and military (AK) variants.
Is DG406EWI+ pin-compatible with the original DG406?
Yes, DG406EWI+ is a pin-compatible plug-in upgrade for the industry-standard DG406, as stated in the General Description and Pin Configurations sections. It uses the identical 28-pin Wide SO footprint, pin numbering, and signal assignments-including V+, V-, GND, EN, A0–A3, S1–S16, and D. No PCB layout changes are required when replacing legacy DG406CWI+ or DG406DJ+ with DG406EWI+.
What supply configurations does DG406EWI+ support?
DG406EWI+ supports both dual-supply (±4.5V to ±20V) and single-supply (+5V to +30V) operation. In single-supply mode, V− is connected to GND. Unbalanced supplies (e.g., +24V and -5V) are also permitted, provided the total voltage difference does not exceed +44V. The analog signal range scales with supply rails-e.g., ±10V with ±15V supplies-and is explicitly defined in the Electrical Characteristics tables.
How does DG406EWI+ handle overvoltage conditions on analog inputs?
DG406EWI+ includes internal clamping diodes on all analog (S1–S16, D) and digital (A0–A3, EN) pins, limiting input voltages to within ~0.7V of V+ or V−. For operation beyond Absolute Maximum Ratings, external series diodes can be added per Figure 1 in the datasheet-reducing analog range by 1V but preserving low RON and leakage performance. ESD protection exceeds 2000V per MIL-STD-883 Method 3015.7.
What is the maximum guaranteed on-resistance flatness for DG406EWI+?
The maximum guaranteed on-resistance flatness for DG406EWI+ is 9Ω, defined as the difference between maximum and minimum RDS(ON) measured across the full specified analog signal range (e.g., ±10V). This parameter is tested and guaranteed per Note 4 in the Electrical Characteristics section and applies to both dual- and single-supply operation across the full -40°C to +85°C temperature range.
