Product details
Overview
DG406EWI+T 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 low signal distortion and rail-to-rail analog handling.
For engineers reviewing the DG406EWI+T datasheet, DG406EWI+T pinout, DG406EWI+T application, or DG406EWI+T equivalent, key selection criteria include guaranteed on-resistance flatness (9Ω max), input 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+T implements a CMOS transmission-gate architecture with decoder-driven address selection (A0–A3) and active-low enable (EN), supporting bidirectional analog signal routing between one common terminal (D) and any of 16 source terminals (S1–S16). Its design ensures symmetrical conduction and minimal charge injection during switching.
It features rail-to-rail analog signal handling across its full supply range, with guaranteed performance over -40°C to +85°C. The device maintains low off-leakage (<5nA at +85°C) and low power consumption (1.25mW max), making it suitable for battery-sensitive and high-precision measurement circuits where signal integrity and thermal stability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RDS(ON)) | 100Ω max - ensures minimal voltage drop and gain error in signal paths up to ±10V |
| On-Resistance Matching | 8Ω max - guarantees consistent gain and offset across all 16 channels in multi-channel calibration systems |
| On-Resistance Flatness | 9Ω max - maintains stable RON across full analog signal range (±10V), reducing harmonic distortion |
| Charge Injection | 15pC max - limits voltage glitch on sample-and-hold capacitors, preserving ADC accuracy |
| Input Leakage (IS(OFF)) | 5nA max at +85°C - prevents drift in high-impedance sensor interfaces and long-time-constant integrators |
| Analog Signal Range | ±10V (dual supply) or 0V to +10V (single supply) - supports industrial-level bipolar and unipolar signals |
| Supply Range | ±4.5V to ±20V dual or +5V to +30V single - enables flexible system-level power architecture integration |
Pinout & Package
DG406EWI+T is housed in a 28-pin wide SOIC (SO) package, RoHS-compliant and lead-free, with 0.3" body width and standard JEDEC MS-013AC footprint.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | V+ | Positive supply rail - must be powered before V− and logic inputs to prevent latch-up |
| 2 | D | Bidirectional common terminal - connects to ADC input, DAC output, or instrumentation amplifier |
| 3–4, 11–12 | S1–S8, S9–S16 | 16 analog input/output channels - arranged in two groups for PCB layout optimization |
| 13–14 | N.C. | No internal connection - must remain unconnected; not usable as heatsink or ground tie |
| 15–17 | A0–A2 | Address LSBs - decode 3-bit binary to select one of eight channel pairs |
| 18 | EN | Active-low enable - disables all switches when high, reducing crosstalk and leakage |
| 19–26 | S1–S8 | First 8 analog channels - physically grouped for minimized trace coupling in mixed-signal layouts |
| 27 | V− | Negative supply rail - referenced to GND in single-supply operation |
| 28 | GND | Analog/digital ground reference - requires low-impedance star connection to minimize noise coupling |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG406BRUZ | 16-channel, 75Ω max RON, but only specified for −40°C to +85°C with 100pC max charge injection | Higher charge injection limits use in precision sample-and-hold; lower RON benefits low-voltage signal chains | Select ADG406BRUZ only if on-resistance is prioritized over charge injection and thermal stability |
| MAX4617ESE+ | 8-channel, 60Ω max RON, 5pC max charge injection, but lacks 16-channel density and dual-supply support | Insufficient channel count for full-system multiplexing; superior charge injection suits ultra-high-resolution ADC front-ends | Choose MAX4617ESE+ when channel count is secondary to sub-16-bit charge-error budgets |
Compared with ADG406BRUZ and MAX4617ESE+, DG406EWI+T uniquely balances 16-channel density, 15pC charge injection, and guaranteed −40°C to +85°C performance-making it optimal for space-constrained, thermally demanding data-acquisition modules where channel scalability and signal fidelity are co-prioritized.

FAQ
What is the maximum allowable analog signal range for DG406EWI+T when operated from ±15V supplies?
The DG406EWI+T supports an analog signal range of ±10V when operated from ±15V dual supplies. This is defined by the device's rail-to-rail capability and absolute maximum ratings - signals beyond ±10V risk exceeding safe operating area limits and may cause increased leakage or distortion. Always ensure VS and VD remain within (V− − 0.3V) to (V+ + 0.3V) per the datasheet's Absolute Maximum Ratings table.
Does DG406EWI+T require external pull-up resistors on its address or enable pins?
No, DG406EWI+T does not require external pull-up resistors. Its digital inputs (A0–A3, EN) have CMOS-compatible thresholds (VAL ≤ 0.8V, VAH ≥ 2.4V) and exhibit low input current (±1.0µA max), allowing direct connection to microcontroller GPIOs or FPGA outputs. Internal protection diodes clamp inputs outside V+ or V−, but proper supply sequencing (V+ first, then V−, then logic) remains essential to avoid damage.
Can DG406EWI+T operate with an unbalanced supply such as +24V and −5V?
Yes, DG406EWI+T can operate with unbalanced supplies like +24V and −5V, provided the total supply differential does not exceed +44V and each rail stays within its absolute maximum rating (V+ ≤ 44V, V− ≥ −0.3V). The analog signal range adjusts accordingly - in this example, it spans from −5V to +24V. Performance parameters such as on-resistance and leakage remain valid as long as ambient temperature and voltage stress stay within datasheet limits.
What is the break-before-make interval for DG406EWI+T, and why does it matter in multiplexed systems?
The DG406EWI+T has a guaranteed break-before-make interval of 110ns to 300ns. This ensures that one channel fully disconnects before the next connects - preventing momentary short-circuits between sources, which could damage sensors or corrupt measurements. In multi-sensor data loggers or fault-tolerant control systems, this specification avoids cross-talk-induced transients and preserves signal integrity during dynamic channel switching.
Is DG406EWI+T pin-compatible with older DG406 variants such as DG406DJ+?
Yes, DG406EWI+T is pin-compatible with all industry-standard DG406 variants including DG406DJ+, DG406CWI+, and DG406DN+. All share identical 28-pin wide SOIC pinout, function mapping, and electrical interface. The "E" grade denotes −40°C to +85°C operation, and "WI" specifies the RoHS-compliant wide SO package - making DG406EWI+T a direct plug-in upgrade with improved matching, flatness, and leakage specs over earlier versions.
