Product details
Overview
DG409EUE+T from Maxim Integrated is a dual 4-channel CMOS analog multiplexer/demultiplexer designed for precision signal routing in mixed-signal systems. It features guaranteed 100Ω max on-resistance, 8Ω max channel-to-channel matching, and 15pC max charge injection-enabling high-fidelity sampling in data-acquisition and test equipment.
For engineers reviewing the DG409EUE+T datasheet, DG409EUE+T pinout, DG409EUE+T application, or DG409EUE+T equivalent, key selection criteria include rail-to-rail analog signal handling (±20V dual / +30V single supply), TTL/CMOS-compatible digital control, and -40°C to +85°C industrial temperature operation with TSSOP-16 packaging.
Technical Context
The DG409EUE+T implements dual independent 4:1 analog switch arrays with integrated CMOS address decoding logic. Each channel supports bidirectional signal flow, ±20V dual-supply or +5V to +30V single-supply operation, and exhibits guaranteed on-resistance flatness of 9Ω max across the full analog signal range.
It delivers low dynamic error via 15pC max charge injection and 75ns typical enable turn-on time (tON(EN)), while maintaining <5nA input off-leakage at +85°C. ESD protection exceeds 2000V per MIL-STD-883 Method 3015.7.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | Dual 4-channel analog MUX/DEMUX - two independent 4:1 switch banks (S1A–S4A/DA and S1B–S4B/DB) |
| On-Resistance (rDS(ON)) | 100Ω max - ensures minimal signal attenuation and gain error in precision measurement paths |
| Channel Matching (ΔrDS(ON)) | 8Ω max - enables accurate differential signal routing and ratio-metric measurements |
| Charge Injection | 15pC max - limits voltage glitch and settling error in sample-and-hold circuits |
| Analog Signal Range | ±20V dual supply or +30V single supply - supports rail-to-rail input/output with V− grounded in single-supply mode |
| Supply Voltage Range | ±5V to ±20V dual or +5V to +30V single - accommodates industrial, test, and avionics power architectures |
| Leakage Current (IS(OFF)) | 5nA max at +85°C - preserves signal integrity in high-impedance sensor interfaces |
Pinout & Package
Package: 16-pin TSSOP (U16-1), 4.4mm × 5.0mm body, 0.65mm pitch, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | A0, A1 | Binary address inputs selecting active channel per 4:1 bank (A0 LSB, A1 MSB) |
| 2 | EN | Active-high enable - disables all switches when low, reducing leakage and crosstalk |
| 3 | V− | Negative supply rail - required for dual-supply operation; tied to GND for single-supply use |
| 4–7 | S1A–S4A | Bidirectional analog inputs for first 4:1 switch bank |
| 8, 9 | DA, DB | Common analog outputs - DA for Bank A (S1A–S4A), DB for Bank B (S1B–S4B) |
| 10–13 | S4B–S1B | Bidirectional analog inputs for second 4:1 switch bank (pin order reversed per datasheet top view) |
| 14 | GND | Ground reference - decoupling capacitor placement critical for noise immunity |
| 15 | V+ | Positive supply rail - supplies internal logic and switch driver circuitry |
Key Features
| Feature | Design Value |
|---|---|
| PIN-COMPATIBLE UPGRADE | Direct drop-in replacement for legacy DG409 - no PCB or firmware changes required |
| GUARANTEED CHANNEL MATCHING | 8Ω max rDS(ON) mismatch - eliminates gain skew between parallel signal paths |
| LOW CHARGE INJECTION | 15pC max - reduces hold-mode voltage error in 12-bit+ SAR ADC front-ends |
| Rail-to-Rail Signal Handling | Supports signals from V− to V+ - enables full dynamic range utilization in ±15V instrumentation |
| TTL/CMOS-Compatible Control | VAL ≤ 0.8V / VAH ≥ 2.4V logic thresholds - interoperable with 3.3V and 5V microcontrollers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG409BRUZ | 100Ω typical on-resistance (not guaranteed max); 25pC typical charge injection; operates up to +85°C but only in SOIC-16 package | Lacks guaranteed 8Ω channel matching and 15pC max charge injection specs - less suitable for metrology-grade sampling | Select DG409EUE+T when guaranteed matching and low-charge-injection performance are required for precision acquisition. |
| TS5A23159DRCR | Single-supply only (+1.65V to +5.5V); 0.9Ω typical on-resistance; 12pC typical charge injection; 10-pin WSON package | Not compatible with ±15V or +24V industrial supplies; insufficient voltage range for test equipment or avionics | Choose DG409EUE+T for bipolar/high-voltage analog routing; TS5A23159 suits low-voltage portable instrumentation only. |
Compared with ADG409BRUZ and TS5A23159DRCR, DG409EUE+T uniquely guarantees both 8Ω channel matching and 15pC max charge injection across its full -40°C to +85°C range while supporting ±20V dual supplies - making it the only option qualified for high-accuracy, wide-range industrial and aerospace signal routing.

FAQ
What is the maximum supply voltage rating for DG409EUE+T?
The DG409EUE+T supports dual supplies from ±5V to ±20V and single supplies from +5V to +30V. Absolute maximum ratings specify V+ to V− ≤ 44V and V+ referenced to V− must not exceed -0.3V to +44V. Operation beyond these limits risks permanent damage.
Does DG409EUE+T support rail-to-rail analog signal switching?
Yes, DG409EUE+T supports rail-to-rail analog signal handling - signals can swing from V− to V+ without distortion or clipping. When used with a single +12V supply, V− is connected to GND, allowing 0V to +12V signal routing.
Is DG409EUE+T pin-compatible with the original DG409?
Yes, DG409EUE+T is a pin-compatible plug-in upgrade for the industry-standard DG409. It uses identical TSSOP-16 pinout, logic interface levels, and functional behavior - enabling direct replacement without layout or firmware changes.
What is the guaranteed on-resistance flatness specification for DG409EUE+T?
DG409EUE+T guarantees on-resistance flatness of 9Ω maximum across the specified analog signal range. This parameter defines the difference between maximum and minimum rDS(ON) values measured at signal extremes (e.g., ±10V), ensuring consistent gain regardless of input voltage level.
How does DG409EUE+T perform at elevated temperature?
At +85°C, DG409EUE+T maintains ≤5nA input off-leakage current and ≤100Ω on-resistance. On-resistance increases predictably with temperature - typical rDS(ON) rises from ~60Ω at +25°C to ~95Ω at +85°C under ±15V dual supply, remaining within guaranteed limits.
