Product details
Overview
DG406EUI+ from Maxim Integrated is a 16-channel single-ended CMOS analog multiplexer/demultiplexer designed for precision signal routing in data-acquisition and test equipment. It features guaranteed on-resistance matching ≤8Ω, flatness ≤9Ω, low charge injection ≤15pC, max on-resistance 100Ω, and operates from ±4.5V to ±20V dual supplies or +5V to +30V single supply.
For engineers reviewing the DG406EUI+ datasheet, DG406EUI+ pinout, DG406EUI+ application, or DG406EUI+ equivalent, key selection criteria include channel-to-channel resistance matching, rail-to-rail analog signal handling (±15V), TTL/CMOS-compatible digital control, ESD protection >2000V, and TSSOP-28 packaging for high-density PCB layouts.
Technical Context
The DG406EUI+ implements a CMOS transmission-gate architecture with fully bidirectional analog signal paths and break-before-make switching logic. Its decoder-driven address inputs (A0–A3) select one of 16 Sx inputs to connect to the common D terminal under EN control.
It guarantees monotonic on-resistance behavior across the full analog signal range (±15V at ±15V supplies), with leakage currents <5nA at +85°C and input capacitance of 8pF - enabling low-crosstalk, low-distortion signal routing in high-impedance sampling circuits.

Pinout & Package
Package: 28-pin TSSOP (U28+2), RoHS-compliant, -40°C to +85°C operating temperature range.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 28 | V+, D (DA) | V+ = positive supply pin; D = bidirectional analog common terminal (output for mux, input for demux) |
| 27 | V- | Negative supply pin - sets lower rail for analog signal range and biasing |
| 12 | GND | Ground reference for digital logic and substrate connection |
| 18 | EN | Active-high enable - disables all switches when low, preventing signal coupling during address changes |
| 14–17 | A3–A0 | 4-bit binary address inputs - select one of 16 channels (S1–S16) to connect to D |
| 4–11, 19–26 | S9–S16, S1–S8 | Bidirectional analog channel inputs - support symmetric signal flow in both directions |
| 2, 3, 13 | N.C. | No internal connection - must be left unconnected; not tied to any internal node |
Key Features
| Feature | Design Value |
|---|---|
| PIN-COMPATIBLE UPGRADE | Direct replacement for legacy DG406 with identical pinout and footprint - no PCB redesign required |
| Rail-to-Rail Signal Handling | Supports analog signals from V− to V+ - eliminates level-shifting needs in ±15V systems |
| TTL/CMOS-Compatible Inputs | Logic thresholds (VAL ≤ 0.8V, VAH ≥ 2.4V) interface directly with standard microcontrollers and FPGAs |
| Low Input Off-Leakage | <5nA at +85°C - prevents measurement drift in high-impedance sensor interfaces and electrometer-grade circuits |

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, 28-TSSOP, RON = 75Ω typ, but only guaranteed matching ≤15Ω and charge injection ≤25pC | Higher on-resistance variation and charge injection limit its use in sub-16-bit precision sample-and-hold designs | Preferred where lower typical on-resistance outweighs guaranteed matching requirements |
| MAX4617ESE+ | 8-channel, 16-SO, RON = 60Ω max, but lacks 16-channel density and ±20V dual-supply capability | Not suitable for direct 16-channel replacement; requires two devices and additional address decoding logic | Selected when board space permits discrete channel expansion and lower on-resistance is critical |
Compared with ADG406BRUZ and MAX4617ESE+, the DG406EUI+ uniquely delivers guaranteed 8Ω matching and 15pC charge injection in a 16-channel TSSOP package with ±20V supply support - making it optimal for high-fidelity, high-channel-count data acquisition where parameter consistency is non-negotiable.

FAQ
What is the maximum analog signal range supported by the DG406EUI+?
The DG406EUI+ supports an analog signal range from V− to V+, up to ±15V when operated with ±15V dual supplies. With ±20V supplies, the usable range extends to ±20V, limited only by the absolute maximum ratings. This rail-to-rail capability allows direct interfacing with high-voltage op-amps and sensor front-ends without external level shifting - a key design advantage in precision instrumentation where signal integrity is critical. The DG406EUI+ maintains guaranteed on-resistance flatness across this full range.
Is the DG406EUI+ pin-compatible with older DG406 variants?
Yes, the DG406EUI+ is explicitly designed as a pin-compatible plug-in upgrade for industry-standard DG406 devices, including DG406CJ+, DG406DJ+, and DG406AK+. Its 28-pin TSSOP footprint matches the mechanical and electrical pinout of legacy versions, enabling drop-in replacement without PCB modification. All address, enable, supply, and channel pins retain identical functions and positions - verified in Maxim's official datasheet revision 6 (19-4729). The DG406EUI+ improves upon predecessors with tighter matching and lower charge injection while preserving full backward compatibility.
What is the guaranteed on-resistance matching specification for DG406EUI+?
The DG406EUI+ guarantees on-resistance matching of ≤8Ω maximum between any two channels over the full operating temperature range (−40°C to +85°C) and specified supply conditions. This parameter - defined as ΔRDS(ON) = RON(MAX) − RON(MIN) - is 100% tested and ensures consistent gain scaling across all 16 channels. In practice, this enables high-accuracy differential measurements and multi-sensor calibration schemes without per-channel software compensation. The DG406EUI+ achieves this while maintaining 100Ω max absolute on-resistance - a balance of low loss and tight matching unmatched by most competing 16-channel muxes.
Does DG406EUI+ support single-supply operation?
Yes, the DG406EUI+ supports single-supply operation from +5V to +30V, with V− connected to GND. In this configuration, the analog signal range spans 0V to V+, e.g., 0V to +12V at +12V supply. Electrical characteristics - including on-resistance (120Ω max), matching (12Ω max), and charge injection (10pC typ) - are fully specified and guaranteed across the single-supply range. The DG406EUI+ retains TTL/CMOS-compatible logic thresholds and break-before-make timing regardless of supply mode, simplifying system-level power architecture decisions without sacrificing performance.
What is the ESD rating of DG406EUI+ and how is it tested?
The DG406EUI+ is rated for ESD protection exceeding 2000V per Human Body Model (HBM), tested in accordance with MIL-STD-883 Method 3015.7. This rating applies to all pins, including analog channels, supply rails, and digital inputs. The robustness stems from integrated protection diodes clamping signals to V+ and V−, with forward current limited to safe levels per datasheet absolute maximum ratings. This level of protection ensures reliable handling during board assembly and field service - particularly valuable in automated test equipment where frequent cable insertion and probe contact occur. The DG406EUI+ maintains this rating across its full −40°C to +85°C operating range.
