Product details
Overview
DG411DY+ 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, rail-to-rail analog signal handling (±15V), and TTL/CMOS logic compatibility - enabling use in sample-and-hold circuits and military radio front-ends.
For engineers reviewing the DG411DY+ datasheet, DG411DY+ pinout, DG411DY+ application, or DG411DY+ equivalent, key selection criteria include guaranteed on-resistance flatness (Δ4Ω), low inter-channel RDS(ON) mismatch (3Ω max), ESD tolerance (2000V min), and operation across ±4.5V to ±20V or +10V to +30V supplies.
Technical Context
The DG411DY+ implements four independent NC SPST switches fabricated in a 44V silicon-gate process, supporting bidirectional conduction with matched channel characteristics. Its architecture guarantees monotonic on-resistance over the full analog range and maintains low leakage across temperature without requiring external biasing.
Switch control uses standard TTL/CMOS-compatible inputs referenced to VL (typically +5V), while analog paths operate independently of logic supply. The device requires no power-up sequencing when V+ is applied first, and supports unbalanced supplies such as +24V/–5V - critical for ruggedized test equipment and guidance systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RDS(ON)) | 35Ω max at ±15V - ensures minimal signal attenuation and gain error in precision DC-coupled paths |
| On-Resistance Flatness (ΔRDS(ON)) | Δ4Ω max - preserves linearity across ±15V analog input range for high-fidelity sampling |
| Charge Injection | 10pC max - reduces voltage glitch in sample-and-hold capacitors, minimizing settling time |
| Off-Leakage Current | <5nA at +85°C - prevents drift in high-impedance sensor interfaces and battery-operated systems |
| Supply Range | ±4.5V to ±20V bipolar or +10V to +30V single - enables direct integration into legacy industrial and military power rails |
| ESD Tolerance | 2000V min per Method 3015.7 - provides robust handling during board assembly and field maintenance |
| Switching Time (tON/tOFF) | <150ns / <100ns - supports multiplexing of audio and medium-speed data signals up to ~3MHz |
Pinout & Package
DG411DY+ is housed in a 16-pin narrow SOIC (Small Outline Integrated Circuit) package with standard 1.27mm pitch, JEDEC MS-012AC compliant, and RoHS-compliant lead finish.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 4, 9, 12 | S1–S4, GND | Source terminals (NC switches) and ground reference - S pins connect to load side; GND establishes logic/analog common |
| 2, 5, 6, 7, 8, 10, 11, 13–16 | V−, D1–D4, IN1–IN4, VL, V+ | Negative supply, drain outputs, digital control inputs, logic supply, and positive supply - D pins carry switched analog signals; IN pins accept 0.8V/2.4V logic thresholds |
Key Features
| Feature | Design Value |
|---|---|
| Normally Closed (NC) Configuration | Ensures fail-safe signal continuity during power loss or logic fault - critical for safety-critical guidance and control monitoring paths |
| RDS(ON) Matching Between Channels | 3Ω max mismatch - enables accurate channel-to-channel gain matching in multi-path instrumentation front-ends |
| Rail-to-Rail Analog Signal Handling | Supports ±15V input swing with full on-state conduction - eliminates level-shifting in ±12V industrial PLC I/O modules |
| Low Power Consumption | 35µW max - extends operational life in sealed battery-powered test probes and portable comms gear |
| TTL/CMOS Logic Compatibility | Accepts 0.8V/2.4V thresholds with VL = +5V - simplifies interface to FPGA/CPLD control logic without level translators |

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 max supply, 35Ω RDS(ON), but only 1000V HBM ESD rating and no guaranteed RDS(ON) flatness spec | Lacks Δ4Ω flatness guarantee and 2000V ESD - less suitable for high-reliability military or aerospace sample-hold stages | Prefer DG411DY+ where signal linearity over full range and ESD robustness are mandatory |
| TS5A3157DCKR | Single-channel, 5V-only supply, 0.75Ω RDS(ON), but limited to ±5.5V analog range and no NC configuration | Not quad, not NC, and incompatible with ±15V rails - unsuitable for legacy industrial or military designs requiring drop-in replacement | Select DG411DY+ when replacing aging DG411-family boards or supporting bipolar supply architectures |
Compared with ADG411BRZ and TS5A3157DCKR, DG411DY+ uniquely delivers NC topology, guaranteed on-resistance flatness, and 2000V ESD in a pin-compatible narrow SOIC footprint - making it the only option for upgrading legacy systems without layout changes or signal integrity compromise.

FAQ
What is the operating temperature range for DG411DY+?
The DG411DY+ is rated for –40°C to +85°C operation, verified across all electrical parameters including on-resistance, leakage, and switching times. This range is confirmed in the Ordering Information table and supported by characterization data in Figures DG411-02 and DG411-05. DG411DY+ meets industrial-grade thermal requirements without derating.
Does DG411DY+ support single-supply operation?
Yes, DG411DY+ operates from a single +10V to +30V supply - connect V− to ground and set VL to +5V for TTL compatibility. Electrical Characteristics tables explicitly list single-supply test conditions (e.g., V+ = 12V, V− = 0V), and Figure DG411-04 confirms on-resistance behavior under +12V operation.
Is DG411DY+ pin-compatible with older DG411 variants?
Yes, DG411DY+ uses the same 16-pin narrow SOIC footprint and pinout as DG411CY and other DG411 variants in SO packaging. Pin descriptions (IN1–IN4, D1–D4, S1–S4, V+, V−, GND, VL) match identically across all versions, enabling plug-in upgrades without PCB modification.
What logic voltage should be applied to VL for TTL compatibility?
Apply +5V to VL for TTL-compatible operation, as specified in the Electrical Characteristics tables and Applications Information section. At VL = +5V, input thresholds are guaranteed at VINH = 2.4V and VINL = 0.8V - matching standard TTL logic levels and eliminating need for external level shifters when interfacing with microcontrollers or FPGAs.
How does DG411DY+ handle overvoltage conditions on analog pins?
DG411DY+ includes internal clamping diodes that limit analog pin voltages to V+ +2V and V− –2V, as stated in Absolute Maximum Ratings. For sustained overvoltage protection beyond these limits, external series diodes are recommended per Figure 1 - but DG411DY+ itself tolerates transient excursions within its specified ±44V V+/V− differential limit without damage.
