Product details
Overview
DG411LEDQ-GE3 from Vishay Siliconix is a quad SPST analog switch with normally closed (NC) configuration, designed for precision signal routing in instrumentation and medical systems. It delivers 16 Ω on-resistance, 15 pF channel-on capacitance, <8 pC charge injection, and operates from 3 V to 16 V single supply or ±3 V to ±8 V dual supply - enabling low-distortion switching in battery-powered data acquisition.
For engineers reviewing the DG411LEDQ-GE3 datasheet, DG411LEDQ-GE3 pinout, DG411LEDQ-GE3 application, or DG411LEDQ-GE3 equivalent, key selection criteria include its NC logic polarity, TSSOP-16 package footprint, guaranteed ≤50 ns turn-on time at +12 V, and compatibility with TTL/CMOS control levels across industrial temperature range (–40 °C to +85 °C).
Technical Context
The DG411LEDQ-GE3 implements four independent bidirectional analog switches with complementary logic control: logic "0" (≤0.8 V) enables conduction, while logic "1" (≥2.4 V) disables all channels. Each switch supports rail-to-rail analog signal swing up to supply rails and blocks input voltages beyond V+ or V− via internal clamping diodes.
It uses a monolithic CMOS process optimized for low RDS(on) variation over voltage and temperature, with guaranteed 40 Ω max on-resistance across –40 °C to +85 °C at 12 V supply. Charge injection remains ≤8 pC over full signal range, minimizing transient glitches in sampling circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 16 Ω typical at +12 V - ensures minimal signal attenuation and gain error in precision sensor interfaces |
| Channel-on capacitance | 15 pF - limits bandwidth degradation and crosstalk in high-frequency analog routing |
| Charge injection | 6.6 pC typical - reduces sampling pedestal error in ADC front-ends and sample-hold circuits |
| Turn-on / turn-off time | 16 ns / 9 ns at +12 V - supports >10 MHz multiplexed signal switching without timing skew |
| Analog signal range | 0 V to +12 V (single supply) - enables direct interfacing with unipolar sensors and DAC outputs |
| Logic compatibility | TTL/CMOS - allows direct connection to microcontrollers and FPGAs without level-shifting |
| Supply range | +3 V to +16 V single or ±3 V to ±8 V dual - supports portable, industrial, and mixed-signal power architectures |
Pinout & Package
Package: 16-lead TSSOP (JEDEC MS-012), 4.4 mm × 5.0 mm × 1.2 mm body height, 0.65 mm pitch, lead (Pb)-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 (IN1–IN4) | Digital control inputs | Active-low logic: INx = 0 V enables corresponding switch; compatible with 3.3 V/5 V logic |
| 5, 6, 12, 13 (S1–S4) | Source terminals | Low-impedance analog inputs/outputs; bidirectional conduction when enabled |
| 7, 8, 11, 10 (D1–D4) | Drain terminals | Paired with Sx to form NC SPST paths; internally connected to V− when off |
| 9 (V−) | Negative supply | Required for dual-supply operation; tied to GND in single-supply mode |
| 14 (V+) | Positive supply | Primary power rail; sets upper analog signal limit and logic threshold reference |
| 15 (GND) | Ground reference | Signal and logic return; must be low-impedance for noise-sensitive applications |
| 16 (VL) | Logic supply | Independent 3 V to 5 V rail for digital interface - decouples logic noise from analog path |
Key Features
| Feature | Design Value |
|---|---|
| Normally closed (NC) topology | Ensures fail-safe signal continuity during power loss or logic fault - critical in medical monitoring and safety-critical ATE |
| Low 16 Ω RDS(on) | Minimizes insertion loss and thermal drift in precision gain-setting and calibration paths |
| 15 pF CD(on), 5 pF CS(off) | Reduces frequency-dependent channel coupling and maintains flat response up to 300 MHz (–3 dB) |
| Guaranteed ≤50 ns tON at +12 V | Enables synchronous multi-channel sampling in 20 MSPS data acquisition systems |
| ±3 V to ±8 V dual supply support | Permits bipolar signal handling (e.g., ±5 V audio, sensor bridges) without external level shifters |

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 |
|---|---|---|---|
| MAX4617ESE+ | 18 Ω RDS(on), 12 pF CD(on), 5.5 V max supply, SOIC-16 only | Limited to 5.5 V operation; no ±5 V dual-supply support | Select when operating exclusively at 3.3 V/5 V and requiring lower capacitance in compact PCB layouts |
| ADG1411BRUZ | 1.8 Ω RDS(on), 23 pF CD(on), 36 V max supply, TSSOP-16 | Higher on-capacitance increases crosstalk; superior RDS(on) benefits low-voltage precision | Choose for ultra-low on-resistance needs where 23 pF CD(on) is acceptable and supply exceeds 16 V |
Compared with MAX4617ESE+ and ADG1411BRUZ, DG411LEDQ-GE3 uniquely balances 16 Ω on-resistance, 15 pF on-capacitance, and ±8 V dual-supply flexibility - making it optimal for cost-sensitive, wide-voltage-range instrumentation where NC fail-safe behavior is required.

FAQ
What is the logic polarity of DG411LEDQ-GE3?
The DG411LEDQ-GE3 features active-low logic control: applying logic "0" (≤0.8 V) to IN1–IN4 turns the corresponding SPST switch ON, while logic "1" (≥2.4 V) turns it OFF. This NC (normally closed) behavior ensures signal continuity during power-down or controller reset - a key safety feature in DG411LEDQ-GE3 deployments.
Can DG411LEDQ-GE3 operate from a single 3.3 V supply?
Yes, DG411LEDQ-GE3 supports single-supply operation from 3 V to 16 V. At 3.3 V, it delivers 71 Ω typical RDS(on) and 57 ns tON, with guaranteed ≤110 Ω max and ≤150 ns max across –40 °C to +85 °C. Logic thresholds remain compatible (VIN(L) ≤ 0.4 V, VIN(H) ≥ 2.0 V), ensuring reliable interface with 3.3 V microcontrollers.
What is the maximum analog signal voltage supported by DG411LEDQ-GE3?
DG411LEDQ-GE3 supports analog signals from V− to V+, limited by absolute maximum ratings: V+ to V− ≤ +18 V. In single-supply mode (V− = GND), signals may swing 0 V to V+. In dual-supply mode (e.g., V+ = +5 V, V− = –5 V), signals may swing –5 V to +5 V - verified by guaranteed ±5 V analog range in specifications.
Does DG411LEDQ-GE3 require an external logic supply (VL)?
Yes, DG411LEDQ-GE3 has a dedicated VL pin (Pin 16) that must be connected to a 3 V to 5 V supply. This separates logic interface noise from analog performance. VL may be tied to V+ if V+ is within 3–5 V; otherwise, a local LDO or regulator is recommended to maintain clean digital control for DG411LEDQ-GE3.
Is DG411LEDQ-GE3 pin-compatible with DG412LEDQ-GE3?
No - DG411LEDQ-GE3 and DG412LEDQ-GE3 share identical pinout and package but differ in logic polarity: DG411LEDQ-GE3 is active-low (NC), while DG412LEDQ-GE3 is active-high (NO). Swapping them requires inverting control signals or redesigning firmware logic; physical replacement alone will invert switch behavior in DG411LEDQ-GE3-based systems.
