Product details
Overview
DG406EUI from Maxim Integrated is a 16-channel single-ended CMOS analog multiplexer with rail-to-rail signal handling, 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 low leakage and high channel uniformity.
For engineers reviewing the DG406EUI datasheet, DG406EUI pinout, DG406EUI application, or DG406EUI 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 TSSOP-28 packaging for space-constrained industrial signal routing.
Technical Context
The DG406EUI implements a CMOS transmission-gate architecture with decoded 4-bit address inputs (A0–A3) and active-low enable (EN), supporting bidirectional analog signal routing between one common terminal (D) and 16 independent channels (S1–S16). Its rail-to-rail operation enables full-swing signal handling across the entire supply range without clipping.
Guaranteed performance parameters-including 8Ω max on-resistance matching and 9Ω max on-resistance flatness-are specified over the full operating temperature range (–40°C to +85°C) and validated under both single-supply (+12V) and dual-supply (±15V) conditions, ensuring consistent switching behavior in mixed-signal test and control environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (max) | 100Ω - ensures minimal signal attenuation and voltage drop in precision analog paths |
| On-resistance matching (max) | 8Ω - guarantees consistent gain and offset across all 16 channels in multi-channel measurement |
| On-resistance flatness (max) | 9Ω - maintains linearity over full analog input range (±10V typical), critical for sample-and-hold accuracy |
| Charge injection (max) | 15pC - limits voltage glitch on hold capacitors, enabling sub-12-bit settling in data-acquisition front-ends |
| Input off-leakage (max) | 5nA at +85°C - preserves high-impedance sensor node integrity and long-term DC stability |
| Supply range | +5V to +30V single or ±4.5V to ±20V dual - supports flexible system-level power architecture integration |
| ESD rating | >2000V per MIL-STD 883 Method 3015.7 - provides robust handling during board assembly and field service |
Pinout & Package
DG406EUI is housed in a 28-pin TSSOP package (package code U28+2), RoHS-compliant, with 0.65mm lead pitch and exposed pad for thermal enhancement. Pin 1 is V+, pin 27 is V-, pin 12 is GND, and pin 28 is the bidirectional output (D).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | V+ | Positive supply input - must be powered first in supply sequencing to prevent latch-up |
| 2–3,13 | N.C. | No internal connection - must remain unconnected; floating or tied to GND/V+ violates layout rules |
| 4–11 | S16–S9 | Bidirectional analog channel inputs - support ±20V signal swing when V± are properly biased |
| 12 | GND | Analog/digital reference ground - requires low-impedance star connection to minimize crosstalk |
| 14–17 | A3–A0 | 4-bit binary channel select address - TTL/CMOS-compatible; VAH ≥ 2.4V, VAL ≤ 0.8V |
| 18 | EN | Active-low enable - disables all switches when high; controls power-down current (<1μA) |
| 19–26 | S1–S8 | Bidirectional analog channel inputs - electrically identical to S9–S16; share same RDS(ON) specs |
| 27 | V- | Negative supply input - must be powered after V+; reverse sequencing risks device damage |
| 28 | D | Common bidirectional terminal - connects to ADC input, DAC output, or instrumentation amplifier |
Key Features
| Feature | Design Value |
|---|---|
| PIN-COMPATIBLE UPGRADE | Direct replacement for legacy DG406 - no PCB redesign required; retains identical pinout and footprint |
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - enables full dynamic range utilization in ±15V systems |
| TTL/CMOS digital interface | Logic thresholds (VAL ≤ 0.8V, VAH ≥ 2.4V) ensure interoperability with standard microcontrollers and FPGAs |
| Low power consumption | 1.25mW max at +25°C - reduces thermal load in dense mixed-signal modules and portable test equipment |
| Guaranteed flatness & matching | 9Ω max flatness and 8Ω max matching over –40°C to +85°C - eliminates calibration per channel in production test systems |

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 on-resistance, –40°C to +85°C, TSSOP-28, but 25pC max charge injection and no guaranteed matching spec | Higher charge injection limits use in precision sample-and-hold; lacks channel matching guarantee for multi-sensor calibration | Select when lower on-resistance is prioritized over charge injection and matching specs |
| MAX4617ESE+ | 16-channel, 60Ω max on-resistance, +85°C max temp, SOIC-28, but only single-supply (+3V to +16.5V) operation and no dual-supply support | Cannot replace DG406EUI in ±15V industrial control or test systems requiring bipolar signal handling | Select only for cost-sensitive, single-supply embedded systems where dual-supply capability is unnecessary |
Compared with ADG406BRUZ and MAX4617ESE+, the DG406EUI uniquely delivers guaranteed 8Ω channel matching and 15pC charge injection in a dual-supply–capable TSSOP package-making it the only option for high-accuracy, wide-temperature, rail-to-rail multiplexing in production test and guidance systems.

FAQ
What is the maximum analog signal range supported by the DG406EUI?
The DG406EUI supports rail-to-rail analog signals from V− to V+, enabling full-swing operation up to ±20V with dual supplies or +30V with single supply. At ±15V supplies, the guaranteed analog signal range is ±10V, and flatness (9Ω max) and matching (8Ω max) are validated across this range per datasheet Figure TOC-01 and TOC-02.
Does the DG406EUI require external protection diodes for overvoltage conditions?
No - the DG406EUI includes internal clamping diodes on all analog and digital pins, limiting forward current to 30mA. However, if absolute maximum ratings risk being exceeded (e.g., during supply sequencing faults), external series diodes may be added per Figure 1 in the datasheet; doing so reduces analog range by ±1V but preserves DG406EUI's core on-resistance and leakage specs.
Is the DG406EUI pin-compatible with older DG406 variants like DG406DJ+?
Yes - the DG406EUI shares identical pinout, function mapping, and electrical timing with all DG406 family members including DG406DJ+, DG406CJ+, and DG406DN+. All operate with the same A0–A3 address logic, EN polarity, and S1–S16/D terminal assignments, making DG406EUI a direct drop-in upgrade for legacy designs using TSSOP-28 or other 28-pin packages.
What is the guaranteed on-resistance flatness specification for DG406EUI over temperature?
The DG406EUI guarantees 9Ω maximum on-resistance flatness (ΔRDS(ON)) over its full operating temperature range of –40°C to +85°C, measured at the extremes of the specified analog signal range (e.g., ±10V at ±15V supplies). This is confirmed in the Electrical Characteristics table on page 2 of the datasheet under "RFLAT" with "TA = TMIN to TMAX" condition.
Can DG406EUI operate with unbalanced supplies such as +24V and –5V?
Yes - the DG406EUI supports unbalanced supplies as long as V+ − V− ≤ +44V and each supply remains within its absolute maximum rating (V+ ≤ +44V, V− ≥ –0.3V). Operation at +24V/–5V is explicitly permitted per Applications Information section, though analog signal range becomes limited to V− +1V to V+ −1V due to internal clamp diode drops.
