Product details
Overview
DG411DJ from Vishay Siliconix is a precision monolithic quad SPST CMOS analog switch designed for high-speed, low-error signal routing in bipolar and single-supply systems. It features 25 Ω on-resistance, 110 ns turn-on time, ±15 V analog signal range, 44 V max supply rating, and operates across –40°C to +85°C - ideal for precision data acquisition front-ends.
For engineers reviewing the DG411DJ datasheet, DG411DJ pinout, DG411DJ application, or DG411DJ equivalent, key selection criteria include break-before-make timing behavior, channel-to-channel crosstalk (85 dB), off-isolation (68 dB), charge injection (5 pC), and compatibility with TTL/CMOS logic levels at VL = 5 V.
Technical Context
The DG411DJ implements four independent SPST switches built on Vishay's high-voltage silicon gate process with epitaxial latchup protection. Each switch conducts bidirectionally when ON and blocks signals up to supply rails when OFF, supporting both dual-supply (±15 V) and single-supply (up to 44 V) operation.
Control logic is active-high: logic "1" (≥2.4 V) turns switches OFF; logic "0" (≤0.8 V) turns them ON. The device uses level-shifting circuitry to interface 5 V logic (VL) with ±15 V analog rails, enabling clean signal switching without external translators.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full-rail input/output swing in dual-supply mode without clipping |
| rDS(on) | 25 Ω typical at ±15 V - ensures minimal gain error and THD degradation in precision amplifier paths |
| tON / tOFF | 110 ns / 100 ns - enables sampling rates up to ~4 MHz in multiplexed ADC applications |
| Charge Injection | 5 pC - limits voltage step errors on high-impedance nodes like sample-hold capacitors |
| OIRR / XTalk | 68 dB / 85 dB - suppresses inter-channel interference in multi-channel instrumentation |
| Supply Rating | 44 V max (V+ to V–) - allows robust operation in industrial 24 V and 36 V systems |
| Logic Compatibility | TTL/CMOS with VL = 5 V - eliminates need for level shifters in microcontroller-driven systems |
Pinout & Package
Package: 16-pin plastic DIP (0.3-inch width), through-hole mount, JEDEC MS-001 compliant.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | IN1–IN4 | Digital control inputs - active-low logic: INx = 0 V → corresponding switch ON |
| 5, 6, 13, 14 | S1–S4 | Switch source terminals - bidirectional analog I/O; connect to signal sources |
| 7, 8, 11, 12 | D1–D4 | Switch drain terminals - bidirectional analog I/O; connect to loads or downstream circuitry |
| 9 | V– | Negative supply rail - must be connected for bipolar operation; tied to GND in single-supply mode |
| 10 | V+ | Positive supply rail - supports up to +44 V relative to V– |
| 15 | GND | Analog/digital ground reference - separate from power ground in mixed-signal layouts |
| 16 | VL | Logic supply voltage - sets input threshold; typically 5 V for TTL/CMOS compatibility |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 25 ns minimum delay between switch openings - prevents momentary shorting in multiplexer configurations |
| Ultra-low power dissipation | 0.35 W max - enables use in battery-powered portable test equipment without thermal derating |
| Wide dynamic signal range | ±15 V analog swing with <0.01% THD - preserves fidelity in audio and sensor signal chains |
| Latchup immunity | Epitaxial isolation process - eliminates risk of destructive latchup under overvoltage or ESD stress |
| Low leakage current | ±0.25 nA max off-leakage at ±15 V - critical for high-impedance sensor interfacing and long-hold sample-and-hold circuits |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617CPD+ | Higher rDS(on) (60 Ω), lower supply rating (36 V), no LCC option | Less suitable for ±15 V precision signal paths; better for cost-sensitive 5 V-only systems | Select MAX4617CPD+ only if 5 V single-supply operation and lower cost outweigh on-resistance and voltage range requirements |
| ADG411BNZ | Lower charge injection (3 pC), same 25 Ω rDS(on), but higher tON (150 ns), different pinout | Preferred for ultra-low-offset sample-and-hold; not drop-in due to incompatible pin mapping | Choose ADG411BNZ when charge injection is the dominant error source and board layout can accommodate pinout changes |
Compared with MAX4617CPD+ and ADG411BNZ, the DG411DJ delivers optimal balance of low on-resistance, fast switching, wide supply range, and proven latchup immunity - making it the preferred choice for industrial-grade bipolar analog multiplexing where reliability and signal fidelity are non-negotiable.

FAQ
What is the maximum supply voltage rating for DG411DJ?
The DG411DJ supports a maximum differential supply voltage of 44 V between V+ and V–. In dual-supply operation, this permits configurations such as ±22 V or +36 V / –8 V. For single-supply use, V– is tied to GND and V+ may range from 5 V to 44 V. Absolute maximum ratings must not be exceeded to ensure long-term reliability.
Does DG411DJ support single-supply operation?
Yes, DG411DJ supports single-supply operation from 5 V to 44 V. In this mode, V– is connected to GND, V+ supplies the positive rail, and VL is tied to V+. The device maintains its specified analog signal range (0 V to V+ – 3 V typical) and retains TTL/CMOS-compatible logic thresholds when VL = V+.
What is the logic polarity of DG411DJ control inputs?
The DG411DJ uses active-low logic: an input voltage ≤0.8 V (logic "0") turns the corresponding switch ON, while ≥2.4 V (logic "1") turns it OFF. This is confirmed in the Truth Table on page 4-2 of the Vishay S-52433 datasheet. DG412DJ provides complementary logic polarity.
How does DG411DJ handle charge injection in sample-and-hold circuits?
DG411DJ specifies 5 pC typical charge injection at room temperature with CL = 10 nF. In sample-and-hold applications, this results in a voltage step error of ≤0.5 mV on a 10 nF hold capacitor. Layout best practices - including guard rings and minimized trace capacitance - further reduce effective error in precision implementations of DG411DJ.
Is DG411DJ pin-compatible with other devices in the DG411/412/413 family?
Yes, DG411DJ shares identical pinout and package (16-pin plastic DIP) with DG412DJ and DG413DJ. All three variants use the same physical terminal mapping and mounting footprint, allowing direct PCB substitution when logic configuration or switch topology (NO/NC) aligns with system requirements.
