Product details
Overview
DG1411EEQ-T1-GE3 from Vishay Siliconix is a quad SPST analog switch with normally closed (NC) configuration, designed for precision signal routing in ±15 V, ±5 V, and +12 V systems. It delivers 1.5 Ω on-resistance, 70 ns turn-on time, rail-to-rail analog signal handling, and operates across -40 °C to +125 °C - ideal for medical instrumentation and automated test equipment where low distortion and high channel matching are critical.
For engineers reviewing the DG1411EEQ-T1-GE3 datasheet, DG1411EEQ-T1-GE3 pinout, DG1411EEQ-T1-GE3 application, or DG1411EEQ-T1-GE3 equivalent, key selection criteria include NC logic behavior, TSSOP-16 package compatibility, guaranteed break-before-make timing in multi-switch configurations, and verified performance at ±15 V supply with <0.2 Ω on-resistance flatness.
Technical Context
The DG1411EEQ-T1-GE3 uses a precision CMOS process enabling bi-directional analog switching up to the supply rails, with no VL logic supply required. Its digital inputs feature fixed 0.8 V / 2 V TTL/CMOS thresholds, supporting single-supply (4.5–24 V) or dual-supply (±4.5 V to ±15 V) operation without level-shifting circuitry.
Each of the four independently controlled SPST switches exhibits matched on-resistance (ΔRDS(on) ≤ 0.24 Ω), low charge injection (−41 pC), and minimal parasitic capacitance (CD(ON) = 87 pF, CS(OFF) = 24 pF), ensuring high-fidelity signal integrity in data acquisition and audio routing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 1.5 Ω typical at ±15 V - enables low insertion loss in precision analog paths |
| On-resistance flatness | 0.2 Ω typical - ensures consistent gain and linearity across full analog voltage range |
| Channel matching | 0.04 Ω typical - supports accurate differential and ratiometric measurements |
| Turn-on time | 70 ns typical at ±15 V - suitable for high-speed multiplexing in ATE systems |
| Analog signal range | V− to V+ - supports rail-to-rail signal switching without clipping |
| Supply range | Single: 4.5–24 V; Dual: ±4.5 V to ±15 V - flexible power architecture integration |
| Logic compatibility | 0.8 V / 2 V thresholds - direct interface with 3 V and 5 V microcontrollers |
Pinout & Package
TSSOP-16 package (5.0 mm × 4.4 mm × 1.2 mm), RoHS-compliant and halogen-free, with exposed pad tied to V− in QFN variants (not applicable here); DG1411EEQ-T1-GE3 uses standard TSSOP-16 footprint per Vishay doc #63550.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 (IN1–IN4) | Digital control input | Active-low logic: logic 0 closes switch (NC function); compatible with 3 V/5 V CMOS |
| 5, 6, 10, 11 (S1–S4) | Analog source terminal | Input side of each SPST switch; connects to signal source when closed |
| 7, 8, 14, 15 (D1–D4) | Analog drain terminal | Output side of each SPST switch; routes signal to load or next stage |
| 9 (GND) | Ground reference | Common return for digital logic and substrate bias; not signal ground |
| 12 (V+) | Positive supply rail | Accepts +4.5 V to +24 V (single) or +15 V max (dual); powers analog core |
| 13 (V−) | Negative supply rail | Accepts −4.5 V to −15 V (dual only); sets lower analog rail boundary |
| 16 (N.C.) | No connect | Internally unconnected; must remain floating or grounded per layout guidelines |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1411BRUZ | Pin-compatible TSSOP-16, same NC function, but higher on-resistance (2.1 Ω typ. at ±15 V) | Lower bandwidth (145 MHz vs. 150 MHz) and higher THD (0.005 %) | Select ADG1411BRUZ only if legacy ADI ecosystem integration outweighs 0.6 Ω on-resistance penalty |
| MAX4611ESE+ | SO-16 package, NC function, but wider on-resistance range (2.5 Ω typ. at ±15 V) and slower tON (125 ns) | Limited temperature range (−40 °C to +85 °C vs. +125 °C) | Prefer MAX4611ESE+ only for cost-sensitive industrial designs not requiring extended temperature operation |
Compared with ADG1411BRUZ and MAX4611ESE+, DG1411EEQ-T1-GE3 offers superior on-resistance flatness (0.2 Ω vs. 0.5 Ω/0.8 Ω), tighter channel matching, and full automotive-grade temperature support - making it optimal for high-accuracy medical and test equipment where signal integrity is non-negotiable.

FAQ
What is the logic behavior of DG1411EEQ-T1-GE3?
DG1411EEQ-T1-GE3 implements a normally closed (NC) configuration: a logic low (≤0.8 V) on IN1–IN4 closes the corresponding S–D switch, while a logic high (≥2 V) opens it. This default-closed behavior ensures signal continuity during power-up or controller reset, enhancing system safety in medical and test equipment where open-circuit faults must be avoided.
Does DG1411EEQ-T1-GE3 require a separate VL logic supply?
No, DG1411EEQ-T1-GE3 does not require a VL logic supply. Its digital inputs operate directly from the main V+ and GND rails, with fixed 0.8 V and 2 V logic thresholds compatible with standard 3 V and 5 V CMOS/TTL outputs - simplifying PCB design and reducing BOM count compared to switches needing auxiliary logic supplies.
Can DG1411EEQ-T1-GE3 operate from a single +12 V supply?
Yes, DG1411EEQ-T1-GE3 supports single-supply operation from +4.5 V to +24 V. At +12 V, it delivers 2.5 Ω typical on-resistance and 150 ns maximum turn-on time, maintaining rail-to-rail analog signal handling (0 V to +12 V). This makes DG1411EEQ-T1-GE3 suitable for battery-powered portable instruments and industrial controllers using unipolar supplies.
What is the maximum continuous current rating for DG1411EEQ-T1-GE3 in TSSOP-16?
In TSSOP-16 package, DG1411EEQ-T1-GE3 supports 190 mA maximum continuous switch current at TA = 25 °C, derating to 90 mA at TA = 125 °C. This rating applies per channel under steady-state DC conditions and assumes proper PCB copper area and thermal management per Vishay's recommended pad layout (doc #63550).
How does DG1411EEQ-T1-GE3 achieve low distortion in audio applications?
DG1411EEQ-T1-GE3 achieves 0.0039 % THD at ±15 V by combining ultra-low on-resistance flatness (0.2 Ω), symmetrical CMOS switch architecture, and minimized charge injection (−41 pC). These characteristics prevent harmonic generation and transient glitches during signal transitions - critical for high-fidelity audio routing in broadcast and studio equipment where spectral purity is mandatory.
