Product details
Overview
DG406CWI+T from Maxim Integrated is a 16-channel single-ended CMOS analog multiplexer with guaranteed 100Ω max on-resistance, 8Ω max channel-to-channel 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 DG406CWI+T datasheet, DG406CWI+T pinout, DG406CWI+T application, or DG406CWI+T equivalent, key selection criteria include 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 DG406CWI+T implements a CMOS transmission-gate architecture with decoder-driven address inputs (A0–A3) and an active-low enable (EN) controlling bidirectional analog signal routing between 16 source channels (S1–S16) and a common drain (D). Its rail-to-rail operation supports full analog swing across V− to V+.
Guaranteed parameters include on-resistance matching (8Ω max), on-resistance flatness (9Ω max), and low charge injection (15pC max), all validated over 0°C to +70°C. Dual-supply operation enables symmetric ±15V signal ranges, while single-supply mode connects V− to GND for +12V or +15V systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 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 in multi-channel measurement |
| On-Resistance Flatness | 9Ω max - maintains stable impedance over full ±10V analog signal range, critical for linearity |
| Charge Injection | 15pC max - limits voltage glitch on sample-and-hold capacitors during channel switching |
| Input Off-Leakage | <5nA at +85°C - preserves accuracy in high-impedance sensor interfaces and long-hold applications |
| Supply Range | +5V to +30V single or ±4.5V to ±20V dual - supports industrial, test, and audio systems with varied power rails |
| ESD Protection | >2000V per MIL-STD 883 Method 3015.7 - enhances robustness in benchtop and field-deployed equipment |
Pinout & Package
DG406CWI+T is housed in a 28-pin wide SO (Small Outline) package with gull-wing leads, RoHS-compliant and lead-free. Pin pitch is 0.050", body width 0.300", and total length 0.600".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | V+ | Positive supply input - must be powered before V− and logic signals to prevent latch-up |
| 2 | D | Bidirectional analog output - common node for all 16 switched channels |
| 3,13 | N.C. | No internal connection - must remain unconnected on PCB |
| 4–11 | S16–S9 | Analog input channels - bidirectional, support rail-to-rail signals from V− to V+ |
| 12 | GND | Ground reference - shared return for digital and analog sections |
| 14–17 | A3–A0 | Address inputs - binary-coded selection of active channel (S1–S16) |
| 18 | EN | Enable input - active-low; disables all switches when high |
| 19–26 | S1–S8 | Analog input channels - identical electrical characteristics to S9–S16 |
| 27 | V− | Negative supply input - required for dual-supply operation; tied to GND for single-supply use |
| 28 | D | Bidirectional analog output - duplicate of pin 2; both pins must be connected |
Key Features
| Feature | Design Value |
|---|---|
| PIN-COMPATIBLE UPGRADE | Direct replacement for legacy DG406 with identical pinout and footprint - no PCB redesign needed |
| Rail-to-Rail Signal Handling | Supports analog signals from V− to V+ without clipping - essential for full-scale sensor and audio routing |
| TTL/CMOS-Compatible Control | Accepts standard logic levels (VAL ≤ 0.8V, VAH ≥ 2.4V) - interoperable with microcontrollers and FPGAs |
| Low Power Consumption | 1.25mW max - reduces thermal drift and simplifies thermal management in dense layouts |
| Dual-Supply Flexibility | Operates from ±4.5V to ±20V or +5V to +30V - accommodates both bipolar instrumentation and unipolar industrial systems |

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 temp range, SOIC-28 package | Higher on-resistance flatness (12Ω) and lower ESD rating (1500V); lacks guaranteed 8Ω matching | Preferred where wider temperature range and lower RON outweigh matching and ESD requirements |
| MAX4617ESE+ | 8-channel, 60Ω max on-resistance, +85°C max operating temp, SOIC-16 package | Half the channel count, smaller package, higher leakage (20nA at +85°C), no A3 address line | Selected for space-constrained designs needing fewer channels and lower cost per switch |
Compared with ADG406BRZ and MAX4617ESE+, the DG406CWI+T offers superior channel matching (8Ω vs. 12Ω/-) and higher ESD tolerance (>2000V vs. 1500V/-), making it optimal for precision, multi-channel data acquisition where consistency and ruggedness are critical.

FAQ
What is the maximum operating temperature range for DG406CWI+T?
The DG406CWI+T is rated for operation from 0°C to +70°C. This commercial-grade temperature range is specified in the ordering information and confirmed in the Absolute Maximum Ratings table. The "C" suffix in DG406CWI+T explicitly denotes the 0°C to +70°C grade, distinct from "D" (−40°C to +85°C) or "AK" (−55°C to +125°C) variants. Thermal derating applies above +70°C per the SO package power dissipation curve.
Does DG406CWI+T support single-supply operation?
Yes, DG406CWI+T supports single-supply operation from +5V to +30V. In this configuration, the V− pin must be connected to GND. The device maintains rail-to-rail analog signal handling from 0V to V+, and all guaranteed specifications-including 100Ω max on-resistance and 15pC max charge injection-apply under single-supply conditions as verified in the Electrical Characteristics tables.
Is DG406CWI+T pin-compatible with the original DG406?
Yes, DG406CWI+T is a pin-compatible plug-in upgrade for the industry-standard DG406. The datasheet explicitly states "pin-compatible plug-in upgrades for the industry standard DG406 and DG407", and the pin configurations for DG406CWI+T (28 Wide SO) match the DG406CJ+ (28 Plastic DIP) in function and numbering. All 28 pins retain identical roles, including dual D pins (2 and 28) and N.C. pins (3 and 13).
What is the guaranteed on-resistance flatness specification for DG406CWI+T?
The guaranteed on-resistance flatness for DG406CWI+T is 9Ω maximum. This parameter is defined as the difference between the maximum and minimum on-resistance values measured across the full specified analog signal range (±10V for dual supply, 0V to +10V for single supply), and is validated over the full 0°C to +70°C operating temperature range per the Electrical Characteristics table.
How does DG406CWI+T handle ESD protection?
DG406CWI+T provides ESD protection exceeding 2000V per MIL-STD 883 Method 3015.7. This rating is guaranteed and tested per the manufacturer's qualification process. The protection is implemented via internal diode clamping on all analog and digital pins, with forward current limited to avoid damage. No external protection circuitry is required for typical handling and board-level ESD events within this rating.
