Product details
Overview
DG2031DQ-T1-E3 from Vishay Siliconix is a low-voltage dual SPDT analog switch in MSOP-10 package, featuring 0.75 Ω on-resistance at 2.7 V, −71 dB off-isolation at 100 kHz, and break-before-make switching with 34 ns turn-on/24 ns turn-off times. It operates from 1.8 V to 5.5 V and supports 1.6-V logic-compatible control, ideal for audio routing in battery-powered portable devices.
For engineers reviewing the DG2031DQ-T1-E3 datasheet, DG2031DQ-T1-E3 pinout, DG2031DQ-T1-E3 application, or DG2031DQ-T1-E3 equivalent, key selection criteria include guaranteed rON matching (<0.05 Ω), flatness (<0.2 Ω), ESD protection (>2000 V), and MSOP-10 footprint compatibility with space-constrained PCB layouts.
Technical Context
The DG2031DQ-T1-E3 implements two independent SPDT switches using high-density low-voltage CMOS with built-in epitaxial latchup prevention. Each switch exhibits bidirectional conduction in the ON state and guarantees break-before-make timing to prevent signal shorting during transition.
Its digital interface accepts 1.6 V logic-high and 0.4 V logic-low thresholds across the full supply range (1.8–5.5 V), enabling direct interfacing with low-voltage DSPs and microcontrollers without level-shifting. Analog signal handling is specified from 0 V to V+ with ±10 nA leakage over −40°C to +85°C.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 10 | V+ | Positive supply rail - must be decoupled locally to minimize switching noise coupling |
| 2, 9 | NO1, NO2 | Normally-open switch outputs - connect to destination nodes when corresponding IN is high |
| 3, 8 | COM1, COM2 | Common analog terminals - bidirectional signal path between NC/NO and source |
| 4, 7 | NC1, NC2 | Normally-closed switch outputs - active when corresponding IN is low |
| 5, 6 | IN1, IN2 | Digital control inputs - TTL/CMOS-compatible; no pull-up required |
| Ground | GND | Reference return - separate analog/digital ground not required due to monolithic CMOS design |
Key Features
| Feature | Design Value |
|---|---|
| rON Matching | <0.05 Ω between channels at 2.7 V - ensures matched gain/attenuation in differential or stereo signal paths |
| rON Flatness | <0.2 Ω over full analog range - preserves linearity in precision sensor or audio front-end switching |
| Break-Before-Make | Guaranteed 2–10 ns dead time - prevents momentary shorting of analog sources during state change |
| Charge Injection | 4 pC typical - limits voltage glitch on high-impedance nodes such as ADC inputs or filter capacitors |
| Low Power Consumption | 1.0 µA max supply current - extends battery life in always-on headset detection circuits |

FAQ
What is the maximum analog signal voltage range supported by the DG2031DQ-T1-E3?
The DG2031DQ-T1-E3 supports analog signals from 0 V to V+, where V+ ranges from 1.8 V to 5.5 V. This means the absolute maximum analog voltage is limited by the supply rail - for example, at V+ = 3.3 V, signals may swing from 0 V to 3.3 V. Exceeding V+ on any analog terminal triggers internal clamping diodes, so proper supply rail sequencing is essential in multi-rail systems.
Does the DG2031DQ-T1-E3 require external pull-up or pull-down resistors on its IN pins?
No, the DG2031DQ-T1-E3 does not require external pull-up or pull-down resistors on its IN1 and IN2 pins. Its input thresholds (VINH = 1.6 V min, VINL = 0.4 V max) are designed for direct connection to standard CMOS/TTL logic outputs. The input leakage is ≤1 µA, ensuring clean logic recognition without additional biasing components.
What is the thermal derating specification for the DG2031DQ-T1-E3 in MSOP-10 package?
The DG2031DQ-T1-E3 in MSOP-10 has a power dissipation limit of 320 mW at +70°C ambient, with linear derating of 4.0 mW/°C above that temperature. At +85°C, the allowable power drops to 260 mW. This reflects the package's thermal resistance and must be considered when operating near maximum current (300 mA) or in high-temperature enclosures.
How is break-before-make timing guaranteed in the DG2031DQ-T1-E3?
Break-before-make timing in the DG2031DQ-T1-E3 is guaranteed by internal circuit design - not production testing - with a specified minimum dead time of 2 ns and maximum of 10 ns between NC and NO transitions. This ensures no overlap in conduction states during switching, preventing momentary shorts in sensitive analog signal paths like microphone bias or headphone drivers.
Is the DG2031DQ-T1-E3 pin-compatible with other Vishay analog switches in MSOP-10?
The DG2031DQ-T1-E3 has a unique pinout optimized for dual SPDT operation and is not pin-compatible with other Vishay MSOP-10 analog switches such as the DG2021 or DG2011. Its IN/COM/NO/NC assignments differ, and substituting without layout revision will result in incorrect signal routing or functional failure.
