Product details
Overview
DG408EUE from Maxim Integrated is a precision 1-of-8 CMOS analog multiplexer/demultiplexer designed for bidirectional signal routing in precision data-acquisition and test systems. It delivers guaranteed 100Ω max on-resistance, 8Ω max channel-to-channel matching, 15pC max charge injection, ±5V to ±20V dual-supply or +5V to +30V single-supply operation, and rail-to-rail analog signal handling up to ±15V.
For engineers reviewing the DG408EUE datasheet, DG408EUE pinout, DG408EUE application, or DG408EUE equivalent, this device is selected for high-accuracy analog switching where low leakage (5nA max at +85°C), flat on-resistance over signal range (9Ω max), and TTL/CMOS-compatible digital control are critical in instrumentation, guidance systems, and audio routing.
Technical Context
The DG408EUE implements an 8-channel analog switch matrix with integrated CMOS address decoding logic (A0–A2) and enable control (EN). Its switch architecture uses matched P- and N-channel MOSFETs to achieve symmetrical conduction and rail-to-rail signal swing without body diode limitations.
It operates across wide supply ranges: ±5V to ±20V dual supplies or +5V to +30V single supply (V− tied to GND). All analog terminals (S1–S8, D) tolerate voltages beyond rails via internal clamping diodes, and dynamic performance includes 100ns typical enable turn-on time and 75ns typical transition time at ±15V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (rDS(ON)) | 100Ω max - ensures minimal signal attenuation and gain error in precision gain-setting or sensor front-end paths |
| On-Resistance Matching | 8Ω max - guarantees consistent gain and offset across channels in multi-sensor scanning |
| Charge Injection | 15pC max - limits voltage glitch and settling time in sample-and-hold circuits |
| Analog Signal Range | ±15V at ±15V supplies - supports full-rail operation in industrial ±10V and ±12V systems |
| Input Leakage (IS(OFF)) | 5nA max at +85°C - preserves accuracy in high-impedance sensor interfaces and integrator nodes |
| Supply Range | +5V to +30V single or ±5V to ±20V dual - enables flexible power architecture in mixed-signal embedded systems |
| Enable Turn-On Time | 150ns max - allows fast channel switching in real-time data acquisition at >1MHz scan rates |
Pinout & Package
DG408EUE is housed in a 16-pin TSSOP package (package code U16-1), 4.4mm × 5.0mm footprint, 0.65mm pitch, thermally enhanced for 755mW dissipation at +70°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15, 16 | A0, A1, A2 | 3-bit binary address inputs selecting one of eight analog channels (S1–S8 → D) |
| 2 | EN | Active-low enable: disables all switches when high, prevents channel contention during reconfiguration |
| 3 | V− | Negative supply rail - must be connected for dual-supply operation; tied to GND for single-supply use |
| 4–7 | S1–S4 | Bidirectional analog inputs - electrically identical to S5–S8; support equal conduction in either direction |
| 8 | D | Common bidirectional analog terminal - serves as input (mux mode) or output (demux mode) |
| 9–12 | S8–S5 | Bidirectional analog inputs - numbered descending to match standard decoder truth table ordering |
| 13 | V+ | Positive supply rail - sets upper analog voltage limit and powers internal logic and switch drivers |
| 14 | GND | Ground reference - required for single-supply operation; provides return path for logic and leakage currents |
Key Features
| Feature | Design Value |
|---|---|
| PIN-COMPATIBLE UPGRADE | Direct replacement for legacy DG408 with identical pinout and footprint - no PCB redesign required |
| Rail-to-Rail Signal Handling | Supports analog signals from V− to V+ without clipping - essential for ±10V industrial I/O and audio line-level routing |
| TTL/CMOS-Compatible Inputs | Accepts 0.8V/2.4V logic thresholds - interoperates directly with microcontrollers, FPGAs, and logic families without level-shifting |
| Guaranteed On-Resistance Flatness | 9Ω max variation across full ±15V signal range - maintains linearity in precision measurement front-ends |
| ESD Protection | >2000V per MIL-STD-883 Method 3015.7 - enhances robustness in benchtop test equipment and field-deployed systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRUZ | 100Ω max rDS(ON), but 25pC charge injection and -40°C to +85°C rating only in RU-16 package | Higher charge injection increases hold-step error in precision S/H; same TSSOP footprint | Select DG408EUE when ≤15pC charge injection is mandatory for 14-bit+ acquisition accuracy |
| MAX4617ESE+ | 8-channel, but 400Ω rDS(ON) and no guaranteed channel matching; operates only on +5V single supply | Unsuitable for ±10V signal routing or multi-sensor gain-matched systems | Choose DG408EUE for bipolar signal handling, low on-resistance, and channel uniformity in industrial DAQ |
Compared with ADG408BRUZ and MAX4617ESE+, DG408EUE uniquely combines guaranteed 8Ω channel matching, 15pC charge injection, and ±20V dual-supply capability - making it the only option among the three qualified for high-fidelity, multi-channel, rail-to-rail analog switching in demanding environments.

FAQ
What supply voltage ranges does the DG408EUE support?
The DG408EUE operates with a +5V to +30V single supply (V− connected to GND) or ±5V to ±20V dual supplies. At ±15V, it supports rail-to-rail analog signals from −15V to +15V. Operation at ±5V reduces analog range but maintains functional switching; supply sequencing (V+ first, then V−, then logic) is recommended to avoid latch-up.
Is the DG408EUE pin-compatible with the original DG408?
Yes, the DG408EUE is a pin-compatible plug-in upgrade for the industry-standard DG408. It shares identical pin assignments, footprint, and logic interface (A0–A2, EN, S1–S8, D, V+, V−, GND), allowing direct replacement without PCB modification or firmware changes.
What is the maximum allowable leakage current for DG408EUE at elevated temperature?
The DG408EUE guarantees input off-leakage current of ≤5nA at +85°C, measured across all analog terminals (S1–S8, D) with V− = −15V, V+ = +15V, and EN = high. This specification is 100% tested at hot temperature and correlated at +25°C per datasheet Note 5.
How does the DG408EUE handle charge injection in sample-and-hold applications?
The DG408EUE guarantees ≤15pC maximum charge injection per channel switch event, measured with CL = 1.0nF and VS = 0V. This low value minimizes hold-mode voltage step errors and reduces settling time in precision S/H circuits-critical for maintaining 14-bit+ effective resolution in data-acquisition systems using DG408EUE.
Does the DG408EUE support unbalanced supply configurations?
Yes, the DG408EUE supports unbalanced supplies such as +24V and −5V, provided the difference between V+ and V− does not exceed +44V. The analog signal range adjusts accordingly (e.g., −5V to +24V), and internal clamping diodes protect digital inputs when signals exceed rails by up to 2V.
