Vishay Siliconix DG412DQ-T1-E3

Overview

DG412DQ-T1-E3 from Vishay Intertechnology is a Vishay Siliconix precision monolithic quad SPST CMOS analog switch designed for high-speed, low-error switching of precision analog signals. The DG412 configuration provides four normally open SPST switches with TTL and CMOS compatible logic control, ±15 V analog signal range, 25 Ω typical on-resistance, 110 ns typical turn-on time, and ultra-low 0.35 μW power dissipation.

For engineers reviewing the DG412DQ-T1-E3 datasheet, DG412DQ-T1-E3 pinout, DG412DQ-T1-E3 application, or DG412DQ-T1-E3 equivalent, this device is most relevant for precision data acquisition, automatic test equipment, communication systems, battery-powered equipment, and analog signal routing circuits requiring four low-leakage CMOS switch channels in a 16-pin TSSOP package.

Technical Context

DG412DQ-T1-E3 uses the DG412 normally open control logic: a logic 0 keeps each switch off, while a logic 1 turns the switch on. The family supports ±15 V analog signal handling under dual-supply operation, 5 V to 44 V single-supply operation, and a 44 V maximum V+ to V- supply rating, allowing the switch array to route precision analog signals across a wide dynamic range.

The analog switch specifications include 25 Ω typical drain-source on-resistance, 0.25 nA maximum room-temperature off leakage, 0.1 nA typical on leakage, 5 pC typical charge injection, 35 pF source-on capacitance, 9 pF source-off capacitance, 68 dB off isolation, and 85 dB channel-to-channel crosstalk at 1 MHz test conditions. The -40 °C to +85 °C D-suffix temperature range supports industrial signal-routing designs.

Key Specifications

Pinout & Package

DG412DQ-T1-E3 is supplied in a 16-pin TSSOP package. The TSSOP-16 body provides a compact 0.65 mm pitch surface-mount footprint with 5.00 mm nominal body length and 4.40 mm nominal body width, helping engineers place four analog switch channels, dual supplies, logic supply, and ground reference in space-constrained precision signal-chain layouts.

Key Features

• Quad normally open SPST CMOS analog switch configuration for four independent signal paths.
• ±15 V analog signal range with 44 V maximum V+ to V- supply rating for wide dynamic range switching.
• 25 Ω typical on-resistance for low-error precision analog routing.
• 110 ns typical turn-on time and 100 ns typical turn-off time for fast channel selection.
• 5 pC typical charge injection and low leakage performance for precision data acquisition circuits.
• TTL and CMOS compatible control inputs with single-supply and dual-supply operation capability.

Applications

Equivalent & Alternatives

When evaluating DG412DQ-T1-E3 equivalent devices, engineers should compare switch configuration, normally open or normally closed logic behavior, on-resistance, leakage current, analog signal range, supply mode, charge injection, package, and control-interface requirements.

Compared with DG411DQ-T1-E3, DG412DQ-T1-E3 is optimized for normally open analog signal routing, where a logic-high command connects each switch. DG412DQ-T1-E3 vs DG413DQ-T1-E3 selection depends on switch logic architecture, while DG412DQ-T1-E3 vs DG412DY-T1-E3 selection depends mainly on TSSOP versus SOIC layout and production assembly requirements.

Quality

DG412DQ-T1-E3 should be sourced as original Vishay Intertechnology components through traceable and controlled supply channels. Quality verification procedures may include TSSOP package inspection, top-mark validation, solderability testing, control-input threshold verification, on-resistance screening, leakage-current measurement, switching-time characterization, charge-injection review, and incoming inspection according to precision analog signal-chain production requirements.

Availability

DG412DQ-T1-E3 is available at Aetrix Electronics and suitable for precision data acquisition, automatic test equipment, and low-error analog signal routing platforms requiring stable component supply and repeatable production support.

Supply support may include scheduled delivery planning, volume procurement support, BOM continuity assistance, traceable sourcing management, and long-term availability support for OEM manufacturers, industrial instrumentation developers, communication-equipment designers, and electronics production programs.

For production deployment, confirming the 16-pin TSSOP package, normally open DG412 switch logic, analog signal range, supply configuration, leakage and on-resistance requirements, lifecycle status, environmental specifications, and sourcing continuity helps reduce procurement risk and improve manufacturing stability.

Manufacturer

Vishay Intertechnology supplies Vishay Siliconix analog switch and signal-routing products for precision, industrial, communication, and portable electronics. The DG411, DG412, and DG413 family uses Vishay Siliconix CMOS switch technology to combine wide signal range, low leakage, fast switching, and low-power operation in standard surface-mount packages.
