Product details
Overview
DG412LEDQ-GE3 from Vishay Siliconix is a quad SPST analog switch with complementary logic control (active-low enable), 16 Ω on-resistance, 15 pF channel-on capacitance, and ±5 V / +12 V dual/single supply operation - deployed in precision signal routing for data acquisition systems and medical instrumentation.
For engineers reviewing the DG412LEDQ-GE3 datasheet, DG412LEDQ-GE3 pinout, DG412LEDQ-GE3 application, or DG412LEDQ-GE3 equivalent, key selection criteria include guaranteed 16 Ω RDS(on) at +12 V, sub-10 ns tOFF, <8 pC charge injection, TTL/CMOS compatibility, and TSSOP-16 package thermal performance up to +85 °C.
Technical Context
The DG412LEDQ-GE3 implements four independent bidirectional analog switches controlled by active-low digital inputs (IN1–IN4), enabling simultaneous signal path selection without polarity inversion. Each switch supports rail-to-rail analog voltage swing (0 V to V+ or ±V) and blocks signals up to supply rails when off.
It uses a standard CMOS transmission gate architecture with integrated level-shifting circuitry referenced to VL (logic supply), allowing interface with 3 V, 5 V, or 12 V logic while operating from ±3 V to ±8 V or +3 V to +16 V analog supplies - verified across -40 °C to +85 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 16 Ω max at +12 V single supply - ensures minimal signal attenuation and distortion in low-voltage precision measurement paths |
| Channel-on capacitance | 15 pF typical - limits high-frequency crosstalk and preserves bandwidth in audio/video routing |
| Charge injection | ≤8 pC over full signal swing - prevents DC offset errors in sample-and-hold and ADC front-end circuits |
| Turn-off time | 9 ns typical at +12 V - enables fast channel switching in automated test equipment with ≤50 ns settling |
| Analog signal range | 0 V to +12 V (single) or ±5 V (dual) - supports direct interfacing with sensors, DACs, and op-amp stages |
| Logic compatibility | TTL/CMOS input thresholds (VIL ≤ 0.8 V, VIH ≥ 2.4 V) - allows direct connection to microcontrollers and FPGAs without level shifters |
| Off-isolation | 68.4 dB at 1 MHz - suppresses interference between adjacent channels in multi-channel multiplexers |
Pinout & Package
Package: 16-lead TSSOP (JEDEC MS-012, 5.0 mm × 6.4 mm × 1.2 mm), RoHS-compliant, lead (Pb)-free, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 (IN1–IN4) | Digital control input (active-low) | Drives corresponding switch ON when logic low (≤0.8 V); complements DG411LE's active-high behavior |
| 2, 6, 10, 14 (S1–S4) | Source terminal | Bidirectional analog node - connects to signal source or load; no internal polarity constraint |
| 3, 7, 11, 15 (D1–D4) | Drain terminal | Bidirectional analog node - pairs with Sx to form SPST path; symmetric conduction when ON |
| 4 (V+) | Positive analog supply | Accepts +3 V to +16 V (single) or +3 V to +8 V (dual); powers analog channel core |
| 8 (V−) | Negative analog supply | Required for dual-supply operation (±3 V to ±8 V); sets lower analog rail |
| 12 (GND) | Analog ground reference | Common return for analog signals; separate from logic ground unless tied externally |
| 16 (VL) | Logic supply voltage | Defines input threshold levels; typically tied to +3 V, +5 V, or +12 V depending on controller interface |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply flexibility | Operates from +3 V to +16 V single supply or ±3 V to ±8 V dual supply - eliminates need for dedicated voltage regulators in mixed-signal systems |
| Low distortion switching | 16 Ω RDS(on) with flatness <±1 Ω over 0–10 V swing - maintains gain accuracy in programmable gain amplifier (PGA) configurations |
| Minimal transient artifacts | 6.6 pC typical charge injection - avoids baseline shift in high-impedance sensor interfaces and integrator circuits |
| Fast, deterministic timing | 16 ns tON/9 ns tOFF with <1 ns skew between channels - enables synchronized sampling in multi-channel DAQ |
| Robust isolation | 5 pF source-off capacitance and 68.4 dB off-isolation at 1 MHz - reduces coupling in RF-adjacent or high-speed digital environments |

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 |
|---|---|---|---|
| ADG1412BRUZ | Higher RDS(on) (1.8 Ω typ. but 4.5 Ω max at +15 V), 16-pin TSSOP, ±15 V rating | Targeted at higher-voltage industrial PLC I/O modules requiring >±10 V swing | Select ADG1412BRUZ only if ±15 V operation or sub-2 Ω RDS(on) is required; DG412LEDQ-GE3 offers better cost and leakage performance at ±5 V |
| TS5A3157DCKR | Single-channel, 5 V only, 0.75 Ω RDS(on), SC70-6 package | Used in space-constrained, low-voltage consumer electronics where quad integration is unnecessary | Choose TS5A3157DCKR for ultra-low RDS(on) in single-path 3.3 V systems; DG412LEDQ-GE3 provides quad density and wider supply range |
Compared with ADG1412BRUZ and TS5A3157DCKR, DG412LEDQ-GE3 delivers optimal balance of quad-channel integration, 16 Ω RDS(on) stability across +3 V to +16 V, and <1 nA leakage - making it preferred for mid-range precision instrumentation where supply flexibility and channel count outweigh ultra-low on-resistance needs.

FAQ
What is the maximum supply voltage rating for DG412LEDQ-GE3?
The DG412LEDQ-GE3 supports absolute maximum ratings of V+ to V− = +18 V and V+ to GND = +18 V. For reliable operation, Vishay specifies recommended single-supply range as +3 V to +16 V and dual-supply range as ±3 V to ±8 V. Exceeding +16 V or ±8 V may cause permanent damage or parametric degradation, per Absolute Maximum Ratings table in datasheet E25-0357-Rev. D.
Does DG412LEDQ-GE3 support bidirectional analog signal flow?
Yes, DG412LEDQ-GE3 supports fully bidirectional analog signal flow on all four SPST channels. When enabled, each S–D pair conducts equally well in either direction due to symmetrical CMOS transmission gate design. This enables use in both source-to-load and load-to-source configurations without performance penalty - confirmed by identical RDS(on), leakage, and capacitance specs for S and D terminals.
How does the logic control scheme of DG412LEDQ-GE3 differ from DG411LEDQ-GE3?
DG412LEDQ-GE3 uses active-low logic control: INx = logic low (≤0.8 V) turns the corresponding switch ON, while INx = logic high (≥2.4 V) turns it OFF. In contrast, DG411LEDQ-GE3 uses active-high control (INx high = ON). Both share identical analog specifications and pinout, making them drop-in replacements except for inverted control logic - verified in Truth Table section of datasheet E25-0357-Rev. D.
What is the thermal derating behavior of DG412LEDQ-GE3 in TSSOP package?
The DG412LEDQ-GE3 in 16-pin TSSOP has a power dissipation limit of 450 mW at +75 °C ambient, with linear derating of 7 mW/°C above that temperature. At +85 °C ambient, maximum allowable power drops to 380 mW. This derating applies to total device power (I+ + I− + IL + IGND × supply voltages) and is specified in Absolute Maximum Ratings table - critical for sustained operation in enclosed medical or industrial enclosures.
Is DG412LEDQ-GE3 qualified for use in battery-powered portable equipment?
Yes, DG412LEDQ-GE3 is explicitly designed for battery-powered systems, supporting single-supply operation down to +3 V with only 1 μA max supply current (I+, I−, IL, IGND combined) at room temperature. Its 3 V operation capability, low 16 Ω RDS(on), and <8 pC charge injection make it suitable for handheld meters, portable ECG monitors, and IoT sensor nodes where power efficiency and signal fidelity are jointly constrained.
