Product details
Overview
DG2535DN-T1-E4 from Vishay Siliconix is a low-voltage dual SPDT analog switch in DFN-10 package, featuring 0.35 Ω on-resistance at 2.7 V, −69 dB off-isolation at 100 kHz, and 1.8 V logic compatibility. It enables high-fidelity audio/video signal routing in space-constrained, battery-powered systems such as cellular handsets and headset interfaces.
For engineers reviewing the DG2535DN-T1-E4 datasheet, DG2535DN-T1-E4 pinout, DG2535DN-T1-E4 application, or DG2535DN-T1-E4 equivalent, key selection criteria include guaranteed break-before-make timing, sub-0.05 Ω on-resistance matching between channels, and ESD protection exceeding 2000 V per JESD 22-A114.
Technical Context
The DG2535DN-T1-E4 implements two independent SPDT analog switches with complementary control logic (IN1/IN2), where logic low connects COMx to NCx and logic high connects COMx to NOx. Its CMOS architecture ensures bidirectional conduction in the on-state and guarantees break-before-make switching with ≤6 ns typical transition interval.
Designed for low-voltage operation (1.8 V to 3.3 V supply), it delivers flat on-resistance (<0.2 Ω variation) and tight channel-to-channel rON matching (<0.05 Ω) across the full analog voltage range (0–V+), enabling precision signal routing without gain error or crosstalk-induced distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 0.35 Ω at 2.7 V - enables minimal insertion loss in audio paths and preserves signal integrity in low-amplitude sensor interfaces |
| Off-Isolation | −69 dB at 100 kHz - suppresses coupling between active and inactive signal paths in multi-source routing |
| Break-Before-Make Time | 1–6 ns - prevents momentary shorting during channel switching in critical analog multiplexing |
| Logic Thresholds | VINH = 1.4 V, VINL = 0.5 V - ensures reliable interface with 1.8 V DSP and microcontroller GPIOs |
| ESD Protection | >2000 V HBM - supports robust handling in handheld device assembly and end-user environments |
| Channel Matching | ΔrDS(on) < 0.05 Ω - maintains amplitude balance in stereo audio or differential signal switching |
| Supply Current | 1.0 µA max - minimizes quiescent power draw in always-on portable system blocks |
Pinout & Package
Package: DFN-10 (3 mm × 3 mm, 0.5 mm pitch), lead (Pb)-free, matte tin or NiPdAu termination per JEDEC standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 4, 6, 7, 9 | NC1, NC2, IN1, IN2, GND, COM1 | No-connect pins (1,3) and digital inputs (4,6) isolate unused functions; GND (7) provides low-impedance return path for analog and digital domains |
| 2, 5, 8, 10 | COM2, NO1, NO2, V+ | COM2 (2) and NO1/NO2 (5,8) carry bidirectional analog signals; V+ (10) supplies clean 1.8–3.3 V bias for switch core and level-shifting circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Sub-0.4 Ω On-Resistance | 0.35 Ω at 2.7 V ensures <0.1% gain error in 10 kΩ load audio paths and supports ±300 mA continuous current |
| Guaranteed Break-Before-Make | ≤6 ns maximum td prevents signal shorting during channel transitions-critical for relay replacement and speaker mute sequencing |
| Low Charge Injection | 21 pC typical - limits voltage glitch on high-impedance nodes (e.g., ADC inputs or op-amp feedback paths) |
| 1.8 V Logic Compatibility | VINH/VINL thresholds align with 1.8 V I/O standards, eliminating need for external level shifters in modern SoC interfaces |
| DFN-10 Space Savings | 3 mm × 3 mm footprint reduces PCB area by >40% vs. MSOP-10, supporting ultra-thin mobile form factors |
Applications
| Cellular Phone Audio Routing | Headset Jack Detection & Switching |
|---|---|
Use Scenario: Dynamic reconfiguration of microphone, earpiece, loudspeaker, and accessory jack signals based on plug detection and call state.

IC Role / Device Role / Timing Role: Low-rON analog switch providing bidirectional signal path selection with <0.05 Ω channel matching to preserve stereo balance. Use Value: Eliminates relay size, power, and wear-out issues while delivering 0.35 Ω on-resistance for negligible insertion loss in 32 Ω headphone loads. |
| PCMCIA Card Signal Multiplexing | Battery-Powered Instrumentation Front-End |
Use Scenario: Sharing analog I/O lines (e.g., ADC input, DAC output, sensor excitation) between multiple PCMCIA peripherals via software-controlled switching. IC Role / Device Role / Timing Role: Dual SPDT switch with break-before-make guarantee prevents bus contention when changing peripheral assignments. Use Value: Supports hot-plug operation with 2000 V HBM ESD rating and 0.2 Ω rON flatness to maintain measurement accuracy across full 0–3.3 V input range. | Use Scenario: Selecting between multiple sensors (thermocouple, RTD, strain gauge) feeding a shared precision ADC in portable test equipment. IC Role / Device Role / Timing Role: Low-leakage (±10 nA off-state) analog switch minimizing offset drift and preserving high-impedance sensor node integrity. Use Value: Delivers <0.05 Ω rON matching and 145 pF off-capacitance to avoid settling-time degradation in 16-bit+ data acquisition systems. |
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 |
|---|---|---|---|
| MAX4685EUB+T | Higher rON (0.75 Ω typ), wider supply (1.8–5.5 V), no guaranteed break-before-make | Supports higher-voltage industrial I/O but lacks timing guarantee for critical audio mute sequences | Choose when operating above 3.3 V or requiring wider voltage margin; avoid where glitch-free switching is mandatory |
| ADG732BRUZ-REEL7 | 32-channel, not dual SPDT; 3.5 Ω rON; SPI interface instead of parallel logic | Targets high-channel-count instrumentation, not compact dual-path routing | Choose only for scalable multiplexing with digital control; incompatible pinout and drive architecture |
Compared with MAX4685EUB+T and ADG732BRUZ-REEL7, the DG2535DN-T1-E4 uniquely combines sub-0.4 Ω on-resistance, guaranteed break-before-make, and DFN-10 footprint-making it optimal for space- and fidelity-critical portable audio routing where timing predictability and low loss are non-negotiable.

FAQ
What is the maximum supply voltage rating for the DG2535DN-T1-E4?
The DG2535DN-T1-E4 has an absolute maximum supply voltage (V+ to GND) of +6 V, but its specified operational range is 1.8 V to 3.3 V. Operating beyond 3.3 V may increase on-resistance and degrade off-isolation; design margins should respect the 3.3 V upper limit for guaranteed performance per the datasheet.
Does the DG2535DN-T1-E4 support bidirectional analog signal flow?
Yes, the DG2535DN-T1-E4 supports fully bidirectional analog signal flow in the on-state. Both COM1/COM2 terminals serve as common ports that conduct equally to their respective NO and NC terminals regardless of signal direction-enabling flexible use in transceiver interfaces or sensor excitation circuits.
How does the DG2535DN-T1-E4 achieve guaranteed break-before-make timing?
The DG2535DN-T1-E4 achieves guaranteed break-before-make timing through internal logic design that delays activation of the new path until the previous path is fully disconnected. The datasheet specifies a maximum break-before-make interval (td) of 6 ns across temperature and voltage, verified by functional testing-not just simulation or characterization.
What is the thermal derating behavior of the DG2535DN-T1-E4 in DFN-10 package?
In the DFN-10 package, the DG2535DN-T1-E4 has a thermal derating factor of 14.9 mW/°C above 70 °C ambient. Its maximum power dissipation is 1191 mW at ≤70 °C, decreasing linearly to zero at 150 °C junction temperature-requiring board-level thermal design to maintain TJ within safe limits under sustained 300 mA load.
Is the DG2535DN-T1-E4 pin-compatible with the DG2535DQ-T1-E3 in MSOP-10?
No, the DG2535DN-T1-E4 (DFN-10) is not pin-compatible with the DG2535DQ-T1-E3 (MSOP-10). Although both share identical logic functionality and signal labeling, their pinouts differ: DG2535DN-T1-E4 places V+ at pin 10 and GND at pin 7, whereas DG2535DQ-T1-E3 assigns V+ to pin 10 but GND to pin 5. PCB layout must be redesigned for package migration.
