Product details
Overview
DG406EUI+T 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-designed for precision data-acquisition systems requiring low distortion and minimal switching transients.
For engineers reviewing the DG406EUI+T datasheet, DG406EUI+T pinout, DG406EUI+T application, or DG406EUI+T equivalent, key selection criteria include guaranteed on-resistance flatness (9Ω max), -40°C to +85°C operating range, TSSOP-28 package compatibility, and dual-supply (±4.5V to ±20V) or single-supply (+5V to +30V) operation.
Technical Context
The DG406EUI+T 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 any of 16 source terminals (S1–S16). Its internal decoder eliminates external logic for channel selection.
It features TTL/CMOS-compatible digital control inputs, rail-to-rail analog voltage handling up to ±20V (dual supply) or +30V (single supply), and guaranteed performance across temperature with leakage <5nA at +85°C and ESD protection >2000V per MIL-STD-883 Method 3015.7.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RDS(ON)) | 100Ω max - ensures minimal signal attenuation and gain error in precision measurement paths |
| On-Resistance Matching | 8Ω max - guarantees consistent gain and offset across all 16 channels in multi-channel instrumentation |
| On-Resistance Flatness | 9Ω max - maintains stable impedance over full ±10V analog signal range, critical for linearity in sample-and-hold |
| Charge Injection | 15pC max - limits voltage glitch on hold capacitors, enabling sub-12-bit accuracy in ADC front-ends |
| Analog Signal Range | ±10V (dual supply) or 0V to +10V (single supply) - supports industrial sensor interfaces and audio routing |
| Supply Range | +5V to +30V (single) or ±4.5V to ±20V (dual) - enables flexible power architecture in mixed-signal systems |
| Leakage Current | 5nA max at +85°C - preserves high-impedance node integrity in battery-powered or thermally stressed applications |
Pinout & Package
DG406EUI+T is housed in a 28-pin TSSOP (Thin Shrink Small Outline Package) with 0.65mm lead pitch, RoHS-compliant, and rated for -40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 28 | V+, D | V+ = positive supply input; D = bidirectional common analog terminal (output in mux mode, input in demux mode) |
| 2, 27 | DB, V− | DB = second output (DG407 only); V− = negative supply input - not used in single-supply config |
| 3–11, 19–26 | S1B–S8B, S1A–S8A | 16 independent analog source terminals - S1–S8 mapped to pins 19–26; S9–S16 mapped to pins 4–11 |
| 12 | GND | Ground reference for logic and substrate - must be tied to system ground even in dual-supply operation |
| 13–14, 17 | N.C., A2 | Pins 2, 3, 13 are no-connect; A2 = 3rd address bit - controls channel group selection in 4-bit decode |
| 15–16, 18 | A0, A1, EN | A0/A1 = LSB address bits; EN = active-low enable - disables all switches when high, reducing crosstalk and leakage |
| 20–23 | A3, S16, S15, S14 | A3 = MSB address bit; S14–S16 = high-order analog inputs - full 16-channel selection requires all four address lines |
Key Features
| Feature | Design Value |
|---|---|
| Pin-compatible upgrade | Direct replacement for legacy DG406 - no PCB redesign required for performance-critical retrofits |
| Rail-to-rail signal handling | Supports analog signals from V− to V+ - eliminates level-shifting in ±15V op-amp or sensor signal chains |
| Guaranteed channel matching | 8Ω max RDS(ON) mismatch - enables accurate ratio-metric measurements across multiple channels |
| Low charge injection | 15pC max - reduces hold-step error in 12-bit+ sampling systems without external correction |
| TTL/CMOS-compatible control | Logic thresholds at 0.8V/2.4V - interoperates directly with microcontrollers and FPGAs without level shifters |

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 RDS(ON), -40°C to +85°C, TSSOP-28, but 25pC charge injection (vs. 15pC) | Higher charge injection limits use in >12-bit sample-and-hold; otherwise suitable for general-purpose routing | Select ADG406BRUZ if lower on-resistance is prioritized over charge injection; verify hold-capacitor settling in target ADC interface. |
| MAX4617ESE+ | 8-channel, 60Ω max RDS(ON), -40°C to +85°C, SOIC-16, no A3 pin - half channel count, smaller package | Not scalable to 16-channel systems; requires two devices and additional decoding logic for equivalent functionality | Choose MAX4617ESE+ only for space-constrained 8-channel designs where footprint reduction outweighs channel count loss. |
Compared with ADG406BRUZ and MAX4617ESE+, the DG406EUI+T uniquely delivers 16-channel density with 15pC charge injection and guaranteed 8Ω matching in TSSOP-28 - making it optimal for high-fidelity, multi-channel data acquisition where channel consistency and switching fidelity are non-negotiable.

FAQ
What is the maximum analog signal voltage range supported by DG406EUI+T?
DG406EUI+T supports an analog signal range of ±10V when operated from ±15V dual supplies, or 0V to +10V with +12V single supply. The device maintains rail-to-rail operation - signals may swing from V− to V+ - and is rated for absolute maximum analog voltages of (V− − 2V) to (V+ + 2V), per internal clamping diodes.
Is DG406EUI+T pin-compatible with the original DG406 series?
Yes, DG406EUI+T is explicitly designed as a pin-compatible plug-in upgrade for industry-standard DG406 devices. It retains identical pinout, function mapping, and package outline (TSSOP-28), enabling drop-in replacement without PCB modification while delivering improved specs including tighter on-resistance matching (8Ω vs. older 15Ω spec) and lower charge injection (15pC vs. 25pC).
What is the enable timing behavior of DG406EUI+T?
DG406EUI+T exhibits 105ns typical enable turn-on time (tON(EN)) and 80ns typical enable turn-off time (tOFF(EN)) under ±15V supplies. These values scale with supply voltage - timing doubles at +5V single supply. The break-before-make interval is guaranteed at 110ns min, preventing momentary shorting during channel transitions in DG406EUI+T operation.
Does DG406EUI+T require external protection against overvoltage or ESD?
No external protection is required for standard operation: DG406EUI+T includes on-chip ESD protection rated >2000V per MIL-STD-883 Method 3015.7. However, if supply sequencing cannot be guaranteed (V+ before V− before logic), external series diodes are recommended to prevent latch-up - though this reduces usable analog range by ~1V per rail, as documented in the DG406EUI+T application notes.
How does temperature affect on-resistance in DG406EUI+T?
In DG406EUI+T, on-resistance increases with temperature: at ±15V dual supply, RDS(ON) rises from ~100Ω at +25°C to ~175Ω at +85°C (max). The datasheet guarantees matching (8Ω max) and flatness (9Ω max) across the full -40°C to +85°C range, ensuring predictable channel-to-channel variation despite absolute RDS(ON) drift.
