Product details
Overview
DG2531DQ-T1-E3 from Vishay Siliconix is a dual single-pole double-throw (SPDT) analog switch optimized for low-voltage battery-powered systems, featuring 0.4 Ω on-resistance at 2.7 V, −69 dB off-isolation at 100 kHz, and guaranteed break-before-make timing. It operates from 1.8 V to 5.5 V supply and supports 1.6 V logic-compatible control inputs.
For engineers reviewing the DG2531DQ-T1-E3 datasheet, DG2531DQ-T1-E3 pinout, DG2531DQ-T1-E3 application, or DG2531DQ-T1-E3 equivalent, key selection criteria include sub-1 Ω rON matching (<0.05 Ω), fast 40/35 ns turn-on/turn-off times, MSOP-10 footprint constraints, and ESD robustness (>2000 V HBM).
Technical Context
The DG2531DQ-T1-E3 implements two independent SPDT switches in a single MSOP-10 package, each with matched COM–NO and COM–NC paths. Its CMOS architecture ensures bidirectional conduction, flat rON (<0.2 Ω variation over full analog range), and guaranteed break-before-make switching to prevent signal shorting.
Control logic is active-high: IN = 0 V turns NC paths ON and NO paths OFF; IN = V+ reverses state. Input thresholds are fixed at VINL ≤ 0.5 V and VINH ≥ 1.4 V across −40 °C to +85 °C, enabling reliable interfacing with low-voltage DSPs and microcontrollers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - Enables direct integration into Li-ion (3.0–3.7 V) and dual-cell alkaline (3.0 V) systems without level-shifting. |
| On-Resistance (rON) | 0.4 Ω typ. at 2.7 V - Minimizes signal attenuation and power loss in audio routing and sensor multiplexing paths. |
| Off-Isolation (OIRR) | −69 dB at 100 kHz - Ensures >2000:1 signal rejection between inactive channels in multi-source audio/video switching. |
| Switching Speed | tON = 40 ns, tOFF = 35 ns - Supports high-speed data path reconfiguration in PCMCIA and USB peripheral switching. |
| ESD Protection | >2000 V HBM - Eliminates need for external TVS diodes in handheld device front-end signal paths. |
| Logic Compatibility | 1.6 V input threshold - Directly interfaces with 1.8 V I/O domains of modern SoCs and baseband processors. |
| Operating Temperature | −40 °C to +85 °C - Qualified for industrial-grade operation in automotive infotainment and portable medical devices. |
Pinout & Package
Packaged in a space-saving MSOP-10 (3.0 mm × 3.0 mm × 1.0 mm), the DG2531DQ-T1-E3 uses a thermally enhanced exposed pad design for improved power dissipation in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 10 | NO1, NO2, COM1, COM2 | Normally-open and common terminals for dual SPDT switch paths; bidirectional analog signal routing capability. |
| 2, 9 | COM2, COM1 | Shared analog common nodes - must be connected to signal source/sink; not internally tied. |
| 4, 7 | IN1, IN2 | Digital control inputs - active-high logic; drive directly from 1.8 V GPIO without pull-up resistors. |
| 5 | GND | Analog/digital ground reference - requires low-impedance connection to PCB ground plane for optimal crosstalk performance. |
| 6 | NC1 | No-connect terminal - left unconnected per datasheet; no internal connection or function. |
| 10 | V+ | Positive supply rail - powers both analog and digital sections; bypass capacitor (0.1 μF) required adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| Sub-1 Ω rON matching | ΔrDS(on) ≤ 0.05 Ω - Ensures identical gain/attenuation across dual channels in stereo audio switching applications. |
| Guaranteed break-before-make | td ≤ 4 ns - Prevents momentary short-circuit between NO and NC paths during state transition, critical for relay replacement. |
| Low charge injection | 54 pC - Reduces voltage glitch on high-impedance nodes (e.g., ADC inputs), minimizing post-switch settling time. |
| Flat rON vs. analog voltage | rON flatness ≤ 0.2 Ω - Maintains consistent signal integrity across full 0–V+ analog swing in video routing. |
| Thermal latchup immunity | Epi-layer isolation - Eliminates risk of destructive latchup under transient overvoltage or hot-swap conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4680EUB+T | Higher rON (0.8 Ω typ. at 3 V); 10-pin µMAX package; no guaranteed break-before-make | Lower bandwidth suitability due to higher capacitance (CNO(on) = 480 pF vs. 403 pF) | Prefer when cost sensitivity outweighs rON and timing guarantees; verify timing sequence in safety-critical paths. |
| ADG732BRUZ | 32-channel SPST vs. dual SPDT; 0.8 Ω rON; TSSOP-32 package; 1.8–5.5 V compatible | Requires external logic for SPDT emulation; larger footprint and higher channel count than needed | Select only when system requires >2 switch paths; avoid for dedicated dual SPDT use cases due to layout and control overhead. |
Compared with MAX4680EUB+T and ADG732BRUZ, the DG2531DQ-T1-E3 delivers superior rON performance, guaranteed break-before-make timing, and minimal footprint-making it optimal for space-constrained, low-distortion audio and portable instrumentation designs where channel matching and glitch-free switching are essential.

FAQ
What is the maximum analog signal voltage range supported by the DG2531DQ-T1-E3?
The DG2531DQ-T1-E3 supports analog signals from 0 V to V+, where V+ ranges from 1.8 V to 5.5 V. Signals exceeding V+ are clamped by internal diodes, so the absolute maximum analog voltage is V+ + 0.3 V per Absolute Maximum Ratings. For a 3.3 V supply, the safe analog range is 0–3.3 V, and DG2531DQ-T1-E3 maintains 0.4 Ω rON and flatness within this band.
Does the DG2531DQ-T1-E3 require external pull-up or pull-down resistors on its IN pins?
No, the DG2531DQ-T1-E3 does not require external pull-up or pull-down resistors on IN1 or IN2. Its input thresholds are specified as VINL ≤ 0.5 V and VINH ≥ 1.4 V across temperature, making it compatible with standard 1.8 V logic outputs. DG2531DQ-T1-E3 draws only 1 µA input current, eliminating loading concerns on driving GPIOs.
How is break-before-make timing guaranteed in the DG2531DQ-T1-E3?
Break-before-make timing in DG2531DQ-T1-E3 is guaranteed by internal circuit design-not production testing-with a maximum td of 4 ns at room temperature. This ensures the NC path fully opens before the NO path closes, preventing momentary shorts. The guarantee holds across −40 °C to +85 °C and all valid supply voltages, and DG2531DQ-T1-E3 includes test circuits in its datasheet verifying this behavior.
Can the DG2531DQ-T1-E3 be used in bidirectional analog signal paths?
Yes, the DG2531DQ-T1-E3 supports fully bidirectional analog signal flow through its COM–NO and COM–NC paths. All channels conduct equally in both directions when ON, with matched rON and flatness specifications applying regardless of signal direction. This makes DG2531DQ-T1-E3 suitable for I²S, USB D+/D−, and other bidirectional interface routing where polarity independence is required.
What thermal derating applies to the DG2531DQ-T1-E3 above 70 °C?
Above 70 °C, the DG2531DQ-T1-E3 requires linear derating of power dissipation at 4.0 mW/°C, as specified in the Absolute Maximum Ratings table. At 85 °C ambient, the maximum allowable power drops from 320 mW (at ≤70 °C) to 260 mW. DG2531DQ-T1-E3's MSOP-10 package includes an exposed pad that must be soldered to a thermal pad for effective heat transfer in high-temperature deployments.
