Product details
Overview
DG411CUE+ from Maxim Integrated is a quad, normally closed (NC), single-pole/single-throw (SPST) analog switch IC designed for precision signal routing in bipolar or single-supply systems. It features 35Ω max on-resistance, <5nA off-leakage at +85°C, 10pC max charge injection, and operates from ±4.5V to ±20V or +10V to +30V supplies-enabling use in battery-operated test equipment and military radios.
For engineers reviewing the DG411CUE+ datasheet, DG411CUE+ pinout, DG411CUE+ application, or DG411CUE+ equivalent, key selection criteria include guaranteed RON matching (≤3Ω), rail-to-rail analog signal handling (±15.5V), TTL/CMOS logic compatibility, and ESD tolerance ≥2000V per Method 3015.7.
Technical Context
The DG411CUE+ implements four independent NC SPST switches fabricated using a 44V silicon-gate process. Each channel guarantees matched on-resistance (ΔRDS(ON) ≤3Ω) and flat on-resistance over the full analog range (ΔRFLAT(ON) ≤4Ω), ensuring consistent signal attenuation across channels and voltage swing.
It supports dual-supply operation with V+ and V− pins referenced to separate rails, while VL accepts 5V logic-level inputs. Switching is controlled by active-low logic inputs (IN1–IN4), with turn-on time ≤145ns and turn-off time ≤100ns under ±15V conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RDS(ON)) | 45Ω max at ±15V - ensures low insertion loss for audio and instrumentation signals |
| On-Resistance Match (ΔRDS(ON)) | 3Ω max - enables precise channel-to-channel signal balancing in multiplexed systems |
| Charge Injection | 10pC max - minimizes voltage glitch at S/D nodes during switching, critical for sample-and-hold accuracy |
| Off-Leakage Current | <5nA at +85°C - preserves signal integrity in high-impedance sensor interfaces and battery-backed circuits |
| Analog Signal Range | ±15.5V - supports rail-to-rail signal handling without clipping when powered from ±16.5V supplies |
| ESD Tolerance | 2000V min per Method 3015.7 - provides robustness against handling-induced electrostatic discharge |
| Supply Range | ±4.5V to ±20V or +10V to +30V - allows flexible deployment in industrial, military, and portable systems |
Pinout & Package
DG411CUE+ is housed in a 16-pin TSSOP package (package code U16-2), 5.0mm × 4.4mm footprint, 0.65mm pitch, with exposed pad not present (non-QFN variant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Logic input (active-low for NC function) | Controls respective switch closure; compatible with TTL/CMOS 0.8V/2.4V thresholds |
| S1–S4 | Source terminal (normally connected) | Common side of NC switch; tied internally to D when logic = 0 |
| D1–D4 | Drain terminal (normally open) | Switch output side; connects to S only when IN = 0 |
| V+ | Positive supply rail | Bias for P-channel MOSFETs; must be ≥|V−| + 9V for full analog range |
| V− | Negative supply rail | Bias for N-channel MOSFETs; sets lower bound of analog signal swing |
| GND | Circuit ground reference | Return path for logic and supply currents; isolated from analog signal paths |
| VL | Logic supply voltage | Must be 5V for TTL compatibility; ties to V+ for CMOS-level inputs |
Key Features
| Feature | Design Value |
|---|---|
| Normally closed (NC) topology | Ensures default signal continuity during power loss or logic fault-critical for safety-critical guidance systems |
| Rail-to-rail analog signal handling | Supports ±15.5V signals with no distortion, enabling direct interface to op-amp outputs and DACs |
| Low charge injection (10pC max) | Reduces hold-step error in sample-and-hold circuits to sub-mV levels with 1nF hold capacitors |
| TTL/CMOS logic compatibility | Eliminates need for level-shifting circuitry when interfacing with microcontrollers and FPGAs |
| Guaranteed RON flatness (Δ4Ω) | Maintains consistent gain/attenuation across ±15V input range-essential for precision instrumentation front-ends |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG411BRUZ | 44V abs max rating; 35Ω RON; 25pC charge injection; SOIC-16 package | Higher charge injection degrades sample-and-hold accuracy vs. DG411CUE+ | Select when SOIC-16 footprint required and charge injection <10pC is not critical |
| TS5A3157DCKR | Single-channel; 0.75Ω RON; 3.3V-only supply; SC70-6 package | Not quad, not bipolar-capable, incompatible with ±15V signal chains | Select only for low-voltage, single-switch consumer audio routing-not for DG411CUE+ replacement |
Compared with ADG411BRUZ and TS5A3157DCKR, DG411CUE+ uniquely delivers quad NC topology with guaranteed 3Ω RON match, <5nA hot-temperature leakage, and ±20V bipolar operation-making it irreplaceable in precision military and test instrumentation where channel correlation and wide supply margin are mandatory.

FAQ
What is the logic polarity of DG411CUE+ switches?
The DG411CUE+ implements normally closed (NC) SPST switches with active-low logic control: when INx = 0V (logic low), the corresponding Sx–Dx path is closed; when INx = 5V (logic high), the path is open. This behavior is confirmed in the functional diagrams and truth tables of the official Maxim datasheet Rev 7.
Does DG411CUE+ support single-supply operation?
Yes, DG411CUE+ supports single-supply operation from +10V to +30V. In this mode, V− must be connected to ground (0V), and VL must be tied to +5V for TTL compatibility. The analog signal range reduces to 0V to V+ − 1V, as specified in the Electrical Characteristics table for single-supply conditions.
What is the maximum analog signal voltage DG411CUE+ can handle?
DG411CUE+ supports an analog signal range of ±15.5V when operated from ±16.5V supplies. This rail-to-rail capability is explicitly guaranteed in the "Analog Signal Range" parameter (VANALOG = ±15.5V) under dual-supply conditions with V+ = +16.5V and V− = −16.5V.
Is DG411CUE+ pin-compatible with legacy DG411 variants?
Yes, DG411CUE+ shares identical pinout and functionality with other DG411 variants in 16-pin TSSOP (e.g., DG411EUE), including matching IN/S/D/V+/V−/GND/VL assignments. The "C" grade denotes 0°C to +70°C operation, but electrical and mechanical compatibility is preserved across temperature grades in the same package.
How does DG411CUE+ achieve low charge injection?
DG411CUE+ achieves ≤10pC charge injection through matched transistor geometry and optimized gate drive timing in its 44V silicon-gate process. This value is 100% tested and guaranteed across temperature, directly enabling sub-mV hold-step accuracy in precision sample-and-hold circuits using standard 1nF hold capacitors.
