Product details

Overview

DG411LEDQ-T1-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-T1-GE3 datasheet, DG411LEDQ-T1-GE3 pinout, DG411LEDQ-T1-GE3 application, or DG411LEDQ-T1-GE3 equivalent, key selection criteria include guaranteed R_DS(on) ≤ 26 Ω over –40 °C to +85 °C, fast 16 ns t_ON/9 ns t_OFF, TTL/CMOS-compatible logic inputs, and TSSOP-16 package compatibility with space-constrained PCB layouts.

Technical Context

The DG411LEDQ-T1-GE3 implements four independent bidirectional analog switches with complementary logic control: logic "0" (≤0.8 V) enables conduction, logic "1" (≥2.4 V) disables. Each switch supports rail-to-rail analog signal swing up to supply rails (e.g., 0–12 V or ±5 V), with symmetrical on-resistance and leakage performance across all channels.

Its architecture integrates internal level-shifting circuitry referenced to VL (logic supply), allowing independent logic voltage (3 V to 5 V) from analog supply rails. Charge injection is minimized via matched transistor design, and off-isolation exceeds 68 dB at 1 MHz - critical for high-fidelity multiplexing in sensitive measurement front-ends.

Key Specifications

Parameter	Value and Actual Design Meaning
On-resistance	16 Ω typical at 12 V single supply; ensures minimal signal attenuation and gain error in precision sensor interfaces.
Channel-on capacitance	15 pF typical; limits bandwidth degradation and crosstalk in multi-channel audio/video routing.
Charge injection	6.6 pC typical; reduces glitch-induced settling errors in sample-and-hold and ADC input stages.
Turn-on / turn-off time	16 ns / 9 ns typical at 12 V; supports high-speed multiplexing in automated test equipment (ATE) up to ~20 MHz.
Analog signal range	0 to 12 V (single supply) or ±5 V (dual supply); enables full-range signal handling without clipping in mixed-signal systems.
Logic compatibility	TTL/CMOS inputs with 0.8 V low / 2.4 V high thresholds; simplifies interface to microcontrollers and FPGAs without level shifters.
Off-isolation	68.4 dB at 1 MHz; suppresses interference between active and inactive channels in dense analog routing.

Pinout & Package

Package: 16-pin TSSOP (JEDEC MS-012), 5.0 mm × 4.4 mm × 1.2 mm body, 0.65 mm pitch, lead (Pb)-free, RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4 (IN1–IN4)	Digital control input	Active-low enable: logic "0" closes corresponding NC switch; compatible with 3–5 V logic families.
5, 6, 12, 13 (S1–S4)	Source terminal (NC)	Normally connected to D pin when switch is enabled; used as common analog input/output node.
7, 8, 11, 10 (D1–D4)	Drain terminal (NC)	Normally connected to S pin when switch is enabled; forms low-R_DS(on) bidirectional path with S pin.
9 (GND)	Analog/digital ground reference	Common return for analog signals and logic inputs; must be low-impedance to minimize noise coupling.
14 (VL)	Logic supply voltage	Accepts 3–5 V independent of analog supplies; decouples logic threshold from V+ and V− rails.
15 (V−)	Negative analog supply	Supports dual-supply operation down to –8 V; clamped internally to prevent damage from overvoltage.
16 (V+)	Positive analog supply	Accepts 3–16 V; defines upper analog signal limit and powers internal switch transistors.

Key Features

Feature	Design Value
Rail-to-rail analog switching	Full signal swing from V− to V+ without distortion - essential for ±5 V sensor outputs and unipolar 0–12 V DACs.
Low charge injection	6.6 pC max ensures sub-LSB errors in 16-bit ADC sampling circuits with 10 nF hold capacitors.
Bidirectional conduction	Identical R_DS(on) and leakage in either direction - enables flexible signal path assignment in reconfigurable analog backplanes.
Wide supply flexibility	Single 3–16 V or dual ±3–±8 V operation allows use in both portable (3.3 V) and industrial (±5 V) systems without redesign.
High off-isolation	68.4 dB at 1 MHz prevents crosstalk between adjacent channels in 16-channel medical ECG front-ends.

FAQ

What is the maximum supply voltage rating for DG411LEDQ-T1-GE3?

The absolute maximum rating for V+ to V− is +18 V. For reliable operation, Vishay specifies a recommended single-supply range of 3 V to 16 V and dual-supply range of ±3 V to ±8 V. Exceeding these limits risks permanent damage, and operation above 16 V violates the guaranteed R_DS(on) and leakage specifications defined in the DG411LEDQ-T1-GE3 datasheet.

Does DG411LEDQ-T1-GE3 support rail-to-rail analog signal switching?

Yes, DG411LEDQ-T1-GE3 supports rail-to-rail analog signal switching: its analog signal range spans from V− to V+ under all specified supply conditions (e.g., 0–12 V or ±5 V). This capability is confirmed by the VANALOG specification in the datasheet and enables direct interfacing with op-amps, DACs, and sensors operating at supply rails without external level-shifting circuitry.

What is the logic configuration of DG411LEDQ-T1-GE3?

DG411LEDQ-T1-GE3 features a normally closed (NC) configuration with active-low digital control: applying logic "0" (≤0.8 V) to INx closes the corresponding switch, while logic "1" (≥2.4 V) opens it. This is explicitly defined in the truth table for DG411LE in the DG411LEDQ-T1-GE3 datasheet and differentiates it from DG412LE (NO, active-high) and DG413LE (mixed NO/NC).

Can DG411LEDQ-T1-GE3 operate with separate logic and analog supplies?

Yes, DG411LEDQ-T1-GE3 supports independent logic and analog supplies via dedicated VL (pin 14) and V+/V− (pins 16/15) pins. VL accepts 3–5 V and sets logic threshold levels, while V+ and V− define the analog signal range. This separation allows interfacing with 3.3 V microcontrollers while powering analog circuitry from ±5 V - a key feature confirmed in the Functional Block Diagram and Electrical Specifications sections of the DG411LEDQ-T1-GE3 datasheet.

Is DG411LEDQ-T1-GE3 RoHS-compliant and lead (Pb)-free?

Yes, DG411LEDQ-T1-GE3 is RoHS-compliant and lead (Pb)-free, as indicated by the "-GE3" suffix in the part number and confirmed in the Ordering Information table and Material Categorization note of the DG411LEDQ-T1-GE3 datasheet. Vishay documents this compliance per www.vishay.com/doc?99912, and the device meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) requirements.
