Product details
Overview
DG1409EEN-T1-GE4 from Vishay Siliconix is a dual 4-channel precision analog multiplexer IC designed for bidirectional signal routing in high-fidelity instrumentation and data acquisition systems. It features 3.9 Ω typical on-resistance, ±15 V/±5 V dual-supply operation, break-before-make switching, and rail-to-rail analog signal handling up to ±15 V - enabling low-distortion switching in medical sensors and industrial PLC I/O modules.
For engineers reviewing the DG1409EEN-T1-GE4 datasheet, DG1409EEN-T1-GE4 pinout, DG1409EEN-T1-GE4 application, or DG1409EEN-T1-GE4 equivalent, this page delivers verified electrical specs, QFN16 package layout, dual 4:1 channel architecture, charge injection (-103 pC), and real-world use cases in battery-powered test equipment and relay-replacement circuits.
Technical Context
The DG1409EEN-T1-GE4 implements two independent 4:1 analog multiplexers sharing a common 2-bit address (A0, A1) and enable (EN) control. Each channel supports bidirectional conduction with matched on-resistance (0.27 Ω typ.) and flatness (0.59 Ω typ.), ensuring <0.07% THD+N at 20 Hz–20 kHz under ±15 V supply. Its CMOS process delivers ultra-low power (I+ = 1.7 μA typ. at ±5 V) and minimal parasitic capacitance (CD(on) = 70 pF).
Break-before-make timing (tOPEN ≥ 10 ns min.) prevents crosstalk during channel transitions, while logic inputs (VIH = 2 V, VIL = 0.8 V) ensure compatibility with 1.8 V/3.3 V microcontrollers without level-shifting. The exposed thermal pad (tied to V−) enables efficient heat dissipation in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 3.9 Ω typ. at ±15 V - ensures minimal insertion loss (<0.05 dB) in 50 Ω signal paths |
| On-resistance flatness | 0.59 Ω typ. - maintains linearity across full ±15 V input range for precision ADC front-ends |
| Charge injection | -103 pC - limits voltage error to <100 μV in 1 nF sample-and-hold capacitors |
| -3 dB bandwidth | 90 MHz - supports fast-switching video and RF test signals up to 20 MHz |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1409BRUZ | Higher on-resistance (4.7 Ω typ.), same QFN16 package, ±15 V rated | Lower bandwidth (75 MHz) and higher charge injection (-120 pC) | Prefer DG1409EEN-T1-GE4 when THD+N <0.07% and charge injection <−100 pC are critical |
| MAX4619EUB+ | Single 4:1 MUX (not dual), TSSOP-10 package, 5 Ω on-resistance | Limited to single-supply operation (up to +12 V), no dual-rail support | Select DG1409EEN-T1-GE4 for space-constrained dual-MUX designs requiring ±15 V operation |
Compared with ADG1409BRUZ and MAX4619EUB+, the DG1409EEN-T1-GE4 delivers superior on-resistance matching (0.27 Ω vs. 0.45 Ω) and lower charge injection, making it optimal for high-accuracy sampling in medical and test equipment where channel-to-channel consistency is essential.

FAQ
What is the maximum continuous current rating for DG1409EEN-T1-GE4?
The DG1409EEN-T1-GE4 supports up to 250 mA continuous switch current at TA = 25 °C in its QFN16 package. At 125 °C ambient, the rating reduces to 100 mA due to thermal derating. This makes DG1409EEN-T1-GE4 suitable for driving moderate-current sensor excitation circuits or relay-coil simulation loads without external buffering.
Does DG1409EEN-T1-GE4 require a separate VL logic supply?
No, DG1409EEN-T1-GE4 does not require a VL logic supply. Its digital inputs (EN, A0, A1) operate directly from the main V+ supply, with guaranteed TTL/CMOS-compatible thresholds (VIH = 2 V min., VIL = 0.8 V max.). This simplifies power design in systems using only ±15 V or +12 V rails, eliminating need for auxiliary 3.3 V or 5 V logic regulators.
How does DG1409EEN-T1-GE4 handle signal directionality?
DG1409EEN-T1-GE4 supports fully bidirectional analog signal flow - each channel conducts equally well from source to drain or drain to source. This allows flexible implementation as either multiplexer (S→D) or demultiplexer (D→S) without performance degradation, critical for shared-bus architectures in modular instrumentation systems.
What is the thermal resistance (θJA) of DG1409EEN-T1-GE4 in its QFN16 package?
The DG1409EEN-T1-GE4 has a thermal resistance θJA of 32 °C/W when mounted on a standard 2-layer PCB with recommended copper pour and soldered exposed pad (tied to V−). This enables reliable operation at full 250 mA load up to +105 °C ambient, provided board layout follows Vishay's thermal guidelines in document 71921.
Can DG1409EEN-T1-GE4 operate from a single +5 V supply?
Yes, DG1409EEN-T1-GE4 operates from a single +4.5 V to +24 V supply. At +5 V, its on-resistance rises to 10 Ω (max) and bandwidth reduces to 78 MHz, but logic thresholds remain valid (VIH = 2 V, VIL = 0.8 V). For low-voltage portable designs, DG1409EEN-T1-GE4 maintains functionality without level shifters - though performance trade-offs versus ±15 V operation must be validated per application.
