Product details
Overview
DG411DK from Maxim Integrated is a quad, normally closed (NC), single-pole/single-throw (SPST) analog switch designed for precision signal routing in high-reliability 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 military radios and guidance & control systems where low distortion and thermal stability are critical.
For engineers reviewing the DG411DK datasheet, DG411DK pinout, DG411DK application, or DG411DK equivalent, key selection considerations include its NC configuration, CERDIP-16 hermetic package, guaranteed on-resistance flatness (Δ4Ω), bipolar ±4.5V to ±20V or single +10V to +30V operation, and ESD tolerance of 2000V per Method 3015.7.
Technical Context
The DG411DK implements four independent NC SPST switches fabricated in a 44V silicon-gate process, supporting bidirectional conduction with matched channel on-resistance (≤3Ω) and flat on-resistance over full signal range (Δ4Ω). Its logic interface accepts 0.8V/2.4V thresholds and operates with VL referenced to either V+ (CMOS) or +5V (TTL).
Switching performance is specified with tON ≤ 150ns and tOFF ≤ 100ns under ±15V supplies; off-isolation exceeds 68dB and crosstalk remains below –85dB at 1MHz. The device guarantees low leakage (<5nA at +85°C) and low power consumption (35µW max) across its –40°C to +85°C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST, normally closed (NC) configuration - all four switches conduct when logic input is low. |
| On-Resistance (RDS(ON)) | 35Ω max at ±15V - ensures minimal signal attenuation and voltage drop in precision analog paths. |
| On-Resistance Flatness | Δ4Ω max over full analog signal range - maintains consistent gain and linearity across ±15.5V input swing. |
| Charge Injection | 10pC max - reduces glitch-induced errors in sample-and-hold and multiplexed ADC front-ends. |
| Off-Leakage Current | <5nA at +85°C - preserves signal integrity in high-impedance sensor interfaces and battery-operated systems. |
| Supply Range | Bipolar ±4.5V to ±20V or single +10V to +30V - supports wide dynamic range and flexible system-level power architecture. |
| ESD Tolerance | 2000V min per Method 3015.7 - enables robust handling in manufacturing and field-deployed military/aerospace equipment. |
Pinout & Package
DG411DK is housed in a 16-pin CERDIP (ceramic dual in-line package) with hermetic sealing, rated for –40°C to +85°C operation and suitable for high-reliability, extended-lifetime applications including aerospace and defense electronics.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 4, 9, 12 | S1–S4, GND | Source terminals for each switch and ground reference - S pins connect to load side; GND establishes logic and supply return path. |
| 2, 11, 13 | V−, V+, D2 | Negative supply input, positive supply input, and drain terminal for second switch - V+ connects to substrate; V− sets lower rail for bipolar operation. |
| 5, 6, 7, 8, 10, 14–16 | D1, D4, IN4, IN3, VL, IN1, IN2, D3 | Drain terminals (D1–D4), logic inputs (IN1–IN4), and logic supply (VL) - IN pins control switch state; VL must be +5V for TTL or tied to V+ for CMOS compatibility. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports ±15.5V signals with no clipping - enables direct interfacing to op-amp outputs and sensor bridges without level-shifting. |
| Guaranteed on-resistance matching | ≤3Ω difference between any two channels - ensures balanced gain and phase response in differential or multi-channel signal paths. |
| TTL/CMOS logic compatibility | 0.8V/2.4V input thresholds with VL configurable to +5V or V+ - simplifies integration with FPGA, microcontroller, and ASIC control buses. |
| Low power consumption | 35µW max quiescent power - extends battery life in portable test equipment and remote sensing nodes. |
| Hermetic CERDIP packaging | 16-pin ceramic DIP with glass-sealed leads - provides moisture resistance, thermal stability, and long-term reliability in harsh environments. |
Applications
| Sample-and-Hold Circuits | Guidance & Control Systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG411BRZ | Quad NC SPST, 35Ω RDS(ON), but only rated to +85°C and lacks guaranteed Δ4Ω flatness or 2000V ESD rating. | Targeted at commercial industrial systems; not qualified for military temp or ESD-critical deployments. | Select ADG411BRZ only if CERDIP hermeticity and MIL-STD ESD compliance are unnecessary. |
| MAX4611CSE+ | Quad NC SPST with 45Ω RDS(ON), wider ±25V supply range, but higher 20pC charge injection and no CERDIP option. | Suitable for high-voltage test equipment, but less ideal for precision sample-and-hold due to increased glitch energy. | Choose MAX4611CSE+ when extended supply range outweighs need for ultra-low charge injection and hermetic packaging. |
Compared with ADG411BRZ and MAX4611CSE+, the DG411DK uniquely combines CERDIP-16 hermetic reliability, guaranteed on-resistance flatness (Δ4Ω), and 2000V ESD tolerance - making it the preferred choice for mission-critical analog routing where parameter stability and environmental resilience are non-negotiable.

FAQ
What is the operating temperature range of the DG411DK?
The DG411DK is specified for operation from –40°C to +85°C. This extended industrial temperature range is validated across all electrical parameters including on-resistance, leakage current, and switching times, and is enabled by its CERDIP-16 hermetic package. The DG411DK datasheet confirms full parameter compliance within this range, making it suitable for deployment in vehicle-mounted systems and outdoor military electronics where ambient extremes are expected.
Does the DG411DK support single-supply operation?
Yes, the DG411DK supports single-supply operation from +10V to +30V. In this mode, V− must be connected to ground (0V), and VL should be set to +5V for TTL compatibility or tied to V+ for CMOS-level inputs. The device maintains rail-to-rail analog signal handling up to ±12V under +12V single supply, as confirmed in the "Electrical Characteristics-Single Supply" section of the DG411DK datasheet.
What is the significance of the "K" suffix in DG411DK?
Within Maxim's ordering nomenclature, the "K" suffix in DG411DK denotes the 16-pin CERDIP (ceramic dual in-line package) variant rated for –40°C to +85°C operation. This distinguishes it from plastic DIP (J), SO (Y), TSSOP (EUE), and QFN (EGE) versions. The CERDIP construction provides hermetic sealing, superior thermal conductivity, and enhanced reliability for aerospace, defense, and long-life industrial applications.
How does the DG411DK differ from the DG412DK and DG413DK?
The DG411DK is normally closed (NC), meaning all four switches conduct when logic inputs are low; the DG412DK is normally open (NO); and the DG413DK integrates two NC and two NO switches in one package. All three share identical electrical specs (RDS(ON), leakage, charge injection, supply ranges), pinout, and CERDIP-16 packaging - differing only in default switch state and truth table behavior, as shown in the DG411/DG412/DG413 functional diagrams.
Is the DG411DK pin-compatible with legacy industry-standard DG411 devices?
Yes, the DG411DK is a plug-in upgrade for industry-standard DG411 devices, retaining identical pinout, footprint, and logic interface. It improves upon legacy versions with tighter on-resistance matching (≤3Ω vs. unspecified), guaranteed flatness (Δ4Ω), lower off-leakage (<5nA at +85°C), and higher ESD tolerance (2000V vs. unspecified), while maintaining full functional and mechanical compatibility with existing PCB layouts.
