Product details
Overview
DG411LDQ-E3 from Vishay Siliconix is a precision monolithic quad SPST low-voltage CMOS analog switch configured as four independent normally-open switches, with 17 Ω typical RDS(on), 19 ns tON, 12 ns tOFF, and ±3 V to ±6 V dual or 2.7 V to 12 V single supply operation - used in precision audio/video routing and battery-powered data acquisition systems.
For engineers reviewing the DG411LDQ-E3 datasheet, DG411LDQ-E3 pinout, DG411LDQ-E3 application, or DG411LDQ-E3 equivalent, key selection considerations include break-before-make timing (DG413L only), leakage <15 nA at full temperature range, flat on-resistance over signal range, ESD rating of 2000 V, and TSSOP-16 package compatibility with space-constrained PCB layouts.
Technical Context
The DG411LDQ-E3 implements BiCMOS process technology enabling simultaneous high-speed switching and low distortion across wide analog signal ranges. Its control logic follows DG411L truth table: logic "0" (≤0.8 V) turns all four switches ON; logic "1" (≥2.4 V) turns them OFF - distinct from DG412L's inverted control and DG413L's dual NO/NC configuration.
It features integrated level-shifting circuitry referenced to VL pin for TTL/CMOS-compatible digital inputs, supports rail-to-rail analog signal switching (0–12 V single supply or ±5 V dual supply), and maintains <5 pC charge injection and >68 dB off-isolation at 1 MHz - critical for low-error sampling and multiplexing in precision instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) | 17 Ω typical at V+ = 12 V - ensures minimal signal attenuation and thermal drift in precision gain paths |
| tON/tOFF | 19 ns / 12 ns at V+ = 12 V - enables high-throughput multiplexing in >25 MHz sampling systems |
| Analog Signal Range | 0 to 12 V (single) or ±5 V (dual) - supports full-rail signal routing without clamping artifacts |
| Leakage Current | ±15 nA max at full temp range - preserves accuracy in high-impedance sensor front-ends |
| ESD Rating | 2000 V HBM - allows safe handling and integration into unshielded portable test equipment |
| Charge Injection | 5 pC typical - limits voltage glitch on sampled-hold capacitors in ADC driver stages |
| Off-Isolation | 71 dB at 1 MHz - suppresses crosstalk between adjacent channels in multi-signal routing |
Pinout & Package
Package: 16-pin TSSOP (JEDEC MO-153, MS-012), 4.4 mm × 5.0 mm body, 0.65 mm pitch, RoHS-compliant matte tin lead finish (E3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control input | Active-low logic: ≤0.8 V = ON state; ≥2.4 V = OFF state for all four switches |
| S1–S4 | Switch source terminal | Analog input node - connects to signal source; bidirectional current path |
| D1–D4 | Switch drain terminal | Analog output node - connects to load or next stage; fully symmetric with S pins |
| V+ | Positive analog supply | Bias for internal analog switches; must be ≥ V− + 0.3 V and ≤ 13 V |
| V− | Negative analog supply | Reference for dual-supply operation; supports −0.3 V to −6 V range |
| GND | Analog ground reference | Return path for analog signals; separate from digital ground unless system design mandates common ground |
| VL | Logic supply reference | Defines logic threshold (0.8 V / 2.4 V); tied to 5 V or same as V+ for single-supply use |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make action | Guaranteed channel isolation during transition - prevents momentary shorting in multiplexer configurations |
| Flat RDS(on) vs. signal voltage | ≤5 Ω variation across full analog range - maintains consistent gain and linearity in audio paths |
| TTL/CMOS logic compatibility | Direct interface with microcontrollers and FPGAs without level-shifting circuitry |
| Low charge injection (5 pC) | Minimizes voltage step on sampling capacitors - reduces settling error in precision ADC front-ends |
| High off-isolation (71 dB) | Enables clean separation of RF or video signals in shared-path routing applications |
Applications
| Audio Signal Routing | Portable Data Acquisition |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Single-supply only (2.7–5.5 V); 35 Ω RDS(on); no dual-supply support | Limited to low-voltage battery systems; unsuitable for ±5 V industrial signal chains | Select when operating strictly at 3.3 V or 5 V and cost sensitivity outweighs on-resistance performance |
| ADG1411BRUZ | Higher supply range (±5 V to ±22 V); 1.8 Ω RDS(on); 16-lead TSSOP pinout identical | Supports higher-voltage industrial transducers but requires tighter layout for 22 V isolation | Choose for ultra-low on-resistance and extended voltage range where board space permits same footprint |
Compared with DG411LDQ-E3, MAX4617ESE+ trades lower voltage flexibility and higher RDS(on) for lower cost in consumer-grade 3.3 V systems, while ADG1411BRUZ delivers superior on-resistance and wider supply range in identical TSSOP-16 packaging - making it a drop-in upgrade for demanding precision applications.

FAQ
What supply voltage ranges does the DG411LDQ-E3 support?
The DG411LDQ-E3 operates from 2.7 V to 12 V single supply or ±3 V to ±6 V dual supply. At 12 V single supply, RDS(on) is 17 Ω typical; at ±5 V dual supply, it is 20 Ω typical. The VL pin accepts 3 V to 5 V logic supply, and absolute maximum ratings specify V+ to V− ≤ 13 V. These ranges are confirmed in Vishay Document 71397 Rev. F.
Does DG411LDQ-E3 have break-before-make switching behavior?
No - DG411LDQ-E3 implements simple SPST switching with no inherent break-before-make timing. That feature is exclusive to DG413L variants per the functional block diagram and truth table in the DG411L/DG412L/DG413L datasheet. DG411LDQ-E3 switches all four channels simultaneously based on IN1–IN4 logic levels, with tON = 19 ns and tOFF = 12 ns at 12 V.
What is the maximum analog signal voltage the DG411LDQ-E3 can handle?
The DG411LDQ-E3 supports analog signals from 0 V to V+ (single supply) or from V− to V+ (dual supply). With V+ = 12 V and V− = 0 V, the full range is 0–12 V; with V+ = +5 V and V− = −5 V, it is −5 V to +5 V. Signals exceeding these rails are clamped by internal diodes - per Absolute Maximum Ratings, VSX/VDX/VINX must stay within −0.3 V to (V+) + 0.3 V.
Is DG411LDQ-E3 pin-compatible with the legacy DG411 series?
Yes - DG411LDQ-E3 is pin-for-pin compatible with the industry-standard DG411 in TSSOP-16 packaging, as explicitly stated in the datasheet introduction: "The DG411L, DG412L, DG413L are low voltage pin-for-pin compatible companion devices to the industry standard DG411, DG412, DG413 with improved performance." This includes identical pinout, function mapping, and footprint.
What is the leakage current specification for DG411LDQ-E3 over temperature?
DG411LDQ-E3 guarantees switch off-leakage current (IS(off)) of ±15 nA maximum across the full operating temperature range of −40 °C to +85 °C, per the D-suffix limits in the Single Supply 12 V specifications table (Document 71397, page 3). This applies to both source and drain terminals under worst-case bias conditions (VD = 1/11 V, VS = 11/1 V).
