DG1408EN-T1-GE4

Overview

The DG1408EN-T1-GE4 is an 8-channel precision analog multiplexer manufactured by Vishay Siliconix. It operates on a single supply from 4.5 V to 24 V or dual supplies of ±4.5 V to ±16.5 V. The device features a typical on-resistance of 3.2 Ω and a maximum of 4.7 Ω at 25 °C, with a flatness of 0.5 Ω. It supports continuous current up to 250 mA and includes an enable function for switching all channels off. The component utilizes a QFN16 (4 mm x 4 mm) package and operates within a temperature range of -40 °C to +125 °C.

Feature Summary

Break-before-make switching action prevents momentary crosstalk between adjacent channels.
Low parasitic capacitance ensures minimal signal distortion and excellent linearity.
Integrated logic supply allows direct compatibility with low-voltage TTL and CMOS inputs without external VL generation.

Applications

Medical and healthcare equipment
Data acquisition systems
Industrial control and automation
Test and measurement equipment
Battery powered systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package variation and tape-and-reel specifications. Ensure that the voltage ratings and thermal requirements align with the target application environment before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring high channel density in a compact footprint. The integrated logic supply simplifies interface design for microcontrollers operating at lower voltages. Verify that the required on-resistance flatness meets the system's linearity constraints across the full signal range.

Part Context

This part belongs to the DG1408/DG1409 family of precision multiplexers designed for high-performance signal routing. It shares the same core architecture as the DG1409 but provides eight single-ended channels instead of four. Both variants utilize the same QFN16 package and support identical supply voltage ranges.
