Product details
Overview
DG411DY+T 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 45Ω max on-resistance at ±15V, <5nA off-leakage at +85°C, 10pC max charge injection, and rail-to-rail analog signal handling up to ±15.5V. It is used in sample-and-hold circuits and military radios where low distortion and high channel matching are critical.
For engineers reviewing the DG411DY+T datasheet, DG411DY+T pinout, DG411DY+T application, or DG411DY+T equivalent, key selection criteria include guaranteed on-resistance flatness (Δ4Ω max), TTL/CMOS logic compatibility, low power consumption (35µW max), and ESD tolerance of 2000V per Method 3015.7 - all verified across the -40°C to +85°C operating range.
Technical Context
The DG411DY+T implements four independent NC SPST switches fabricated using a 44V silicon-gate process, enabling operation from ±4.5V to ±20V bipolar supplies or +10V to +30V single supply. Its architecture guarantees matched on-resistance (≤3Ω difference between channels) and flat on-resistance (Δ4Ω max) over the full analog signal range.
It supports rail-to-rail signal switching with low charge injection (10pC max) and low off-leakage (<5nA at +85°C), making it suitable for high-precision sampling and low-drift analog paths. Logic inputs are TTL/CMOS-compatible, and VL must be tied to +5V for TTL-level operation or to V+ for CMOS-level operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RDS(ON)) | 45Ω max at ±15V - ensures minimal signal attenuation and voltage drop in precision analog paths |
| On-Resistance Flatness (ΔRDS(ON)) | Δ4Ω max - maintains consistent gain and linearity across full ±15.5V analog input range |
| Charge Injection | 10pC max - limits voltage glitch on sampled hold capacitors, critical for ADC front-ends |
| Off-Leakage Current | <5nA at +85°C - preserves accuracy in high-impedance sample-and-hold and battery-monitoring circuits |
| Supply Range | ±4.5V to ±20V bipolar or +10V to +30V single - enables flexible system-level power architecture design |
| ESD Tolerance | 2000V min per Method 3015.7 - provides robust handling during board assembly and field operation |
| Switching Time (tON/tOFF) | <150ns / <100ns - supports high-speed multiplexing in test equipment and comms systems |
Pinout & Package
DG411DY+T is supplied in a 16-pin narrow SOIC package (package code S16-1), with exposed pad not present - distinct from QFN variants. Pin functions are electrically identical across DG411 family variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 15, 14, 7, 6) | Logic control inputs | Active-low for DG411 (NC): logic '0' closes switch; TTL/CMOS compatible with VL = +5V or V+ |
| D1–D4 (Pins 16, 13, 10, 5) | Analog drain terminals | High-impedance side of NC switch; connects to load or downstream circuitry |
| S1–S4 (Pins 1, 11, 12, 4) | Analog source terminals | Common side of NC switch; typically tied to signal source or reference node |
| V+ (Pin 13) | Positive supply | Bias for internal circuitry and substrate; must be ≥|V−| to maintain 44V max differential |
| V− (Pin 2) | Negative supply | Enables true bipolar operation; clamped internally to prevent breakdown beyond absolute max ratings |
| GND (Pin 3) | Ground reference | Logic ground return; separate from analog signal ground unless system design requires common reference |
| VL (Pin 10) | Logic supply | Defines logic threshold; +5V for TTL compatibility, V+ for CMOS; not required if logic levels match V+/V− rails |
Key Features
| Feature | Design Value |
|---|---|
| Normally closed (NC) topology | Ensures fail-safe signal continuity during power loss or logic fault - critical in guidance & control systems |
| Guaranteed RDS(ON) matching | ≤3Ω max difference between any two channels - enables precise multi-channel calibration without per-channel trimming |
| Rail-to-rail analog signal handling | Supports ±15.5V signals with no clipping - eliminates need for level-shifting in wide-dynamic-range audio or sensor interfaces |
| Low power consumption | 35µW max - extends battery life in portable test equipment and handheld radios |
| Plug-in upgrade path | Pin- and function-compatible with legacy industry-standard DG411 - enables drop-in replacement without layout change |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG411BRZ | 44V abs max rating; 35Ω RDS(ON) typ at ±15V; 25pC charge injection; SOIC-16 package | Higher charge injection limits use in ultra-low-drift sample-and-hold; lower RDS(ON) benefits low-voltage signal paths | Select ADG411BRZ when lower on-resistance outweighs charge injection sensitivity; verify layout compatibility with different pinout (IN/D/S assignments differ) |
| TS5A3157DCKR | Single-supply only (+1.65V to +5.5V); 0.9Ω RDS(ON); 15pC charge injection; SC70-6 package | Not suitable for bipolar or high-voltage analog routing; optimized for low-voltage portable audio and USB switching | Choose TS5A3157DCKR only for 3.3V/5V single-rail systems; cannot replace DG411DY+T in ±15V or rail-to-rail >5V applications |
Compared with ADG411BRZ and TS5A3157DCKR, DG411DY+T uniquely supports bipolar ±20V operation, offers superior charge injection performance (10pC vs. 25pC/15pC), and provides NC default state - making it irreplaceable in high-reliability, high-voltage, fail-safe analog routing.

FAQ
What is the operating temperature range for DG411DY+T?
The DG411DY+T is rated for -40°C to +85°C operation, as confirmed by its ordering code "DY" designation in Maxim's official documentation. This industrial-grade temperature range ensures reliable performance in military radios, guidance systems, and outdoor test equipment where ambient conditions vary widely. All electrical specifications - including <5nA off-leakage and 10pC charge injection - are guaranteed across this full range.
Is DG411DY+T pin-compatible with the original DG411 series?
Yes, DG411DY+T is a plug-in upgrade for industry-standard DG411 devices, maintaining identical 16-pin narrow SOIC pinout and logic behavior. The improved version retains the same IN/D/S terminal assignments and NC functionality while enhancing RDS(ON) matching (≤3Ω), flatness (Δ4Ω), and leakage performance. No PCB changes are required when replacing legacy DG411CJ or DG411CY variants.
Can DG411DY+T operate from a single +12V supply?
Yes, DG411DY+T supports single-supply operation from +10V to +30V. When using +12V, connect V− to ground, set VL to +5V for TTL compatibility, and expect RDS(ON) of ~100Ω (typ) and analog signal range of 0V to +12V. Switching times increase slightly versus ±15V operation, but tON remains under 250ns - sufficient for most data acquisition and routing applications.
What is the maximum analog signal voltage supported by DG411DY+T?
DG411DY+T supports analog signals from V− to V+, with guaranteed operation up to ±15.5V when powered from ±16.5V supplies. The absolute maximum analog range is limited by the supply rails: signals exceeding V+ or falling below V− are clamped by internal diodes. For safe linear operation, keep analog inputs within (V− + 2V) to (V+ − 2V) to avoid forward-biasing protection diodes.
Does DG411DY+T require an external logic supply (VL)?
Yes, VL is required to define logic thresholds. Tie VL to +5V for TTL-compatible inputs (VINH = 2.4V, VINL = 0.8V) or to V+ for CMOS-level operation. Leaving VL unconnected or floating will result in undefined logic behavior. The device draws <1µA from VL, making it compatible with standard microcontroller GPIO or dedicated logic regulators.
