Product details
Overview
DG2535DQ-T1-E3 from Vishay Siliconix is a dual SPDT analog switch optimized for low-voltage battery-powered systems, featuring 0.35 Ω on-resistance at 2.7 V, -69 dB off-isolation at 100 kHz, and guaranteed break-before-make switching. It operates from 1.8 V to 6 V supply, supports 1.4 V logic-high input threshold, and is housed in an MSOP-10 package for compact audio routing in portable devices.
For engineers reviewing the DG2535DQ-T1-E3 datasheet, DG2535DQ-T1-E3 pinout, DG2535DQ-T1-E3 application, or DG2535DQ-T1-E3 equivalent, key selection criteria include on-resistance matching (<0.05 Ω), charge injection (21 pC), crosstalk (-69 dB), and ESD robustness (>2000 V HBM) in space-constrained, low-power signal path designs.
Technical Context
The DG2535DQ-T1-E3 implements two independent SPDT switches with complementary control logic: IN1/IN2 high enables NO1/NO2 conduction while disabling NC1/NC2. Its CMOS process includes epitaxial latch-up prevention and guarantees sub-1 Ω rON flatness (<0.2 Ω) across full analog voltage range (0–V+).
Switching performance is characterized by 52 ns turn-on time, 43 ns turn-off time, and 1–6 ns break-before-make interval at 3 V supply with 50 Ω load and 35 pF capacitance - enabling high-fidelity audio and video signal routing without audible artifacts or signal coupling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 0.35 Ω at 2.7 V - minimizes signal attenuation and power loss in low-voltage audio paths |
| Off-Isolation / Crosstalk | -69 dB at 100 kHz - ensures channel separation in headset and speaker switching applications |
| Charge Injection | 21 pC - limits voltage glitch on COM node during switching, critical for precision ADC/DAC interfaces |
| Logic Thresholds | VINH = 1.4 V, VINL = 0.5 V - compatible with 1.8 V DSP and microcontroller I/O without level shifting |
| ESD Protection | >2000 V HBM - withstands handling and system-level ESD events in handheld consumer electronics |
| Supply Range | 1.8 V to 6 V - supports single-cell Li-ion (3.0–4.2 V) and dual-cell alkaline (2.4–3.2 V) operation |
| Leakage Current | ±10 nA max at 85 °C - preserves battery life in always-on signal monitoring circuits |
Pinout & Package
Package: MSOP-10, lead (Pb)-free, RoHS-compliant, 3 mm × 3 mm footprint with exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 4, 6, 7, 9 | NC1, NC2, COM1, COM2, IN1, IN2 | Non-connected (NC) and common (COM) analog terminals; IN1/IN2 are digital control inputs with 1.4 V logic-high threshold |
| 2, 8 | NO1, NO2 | Normally-open analog switch outputs - conduct to COM when corresponding IN is high |
| 5 | GND | Analog/digital ground reference - must be connected to system ground plane for optimal noise immunity |
| 10 | V+ | Positive supply rail - powers internal switch core and logic; decoupling capacitor required near pin |
Key Features
| Feature | Design Value |
|---|---|
| On-resistance matching | <0.05 Ω between channels - enables balanced stereo audio routing without channel gain mismatch |
| Break-before-make guarantee | 1–6 ns minimum interval - prevents momentary short-circuit between NO and NC paths during state transition |
| Low rON flatness | <0.2 Ω over full 0–V+ analog range - maintains consistent signal integrity across entire audio bandwidth |
| Latch-up immunity | >300 mA per JESD78 - survives transient overcurrent events in portable device hot-swap scenarios |
| Thermal derating | 4.0 mW/°C above 70 °C - defines safe power dissipation envelope for sustained operation in enclosed enclosures |

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 | rON = 0.5 Ω at 3 V; -65 dB OIRR; 10-pin µMAX package | Higher rON and lower isolation limit dynamic range in high-fidelity audio paths | Preferred where wider supply range (1.8–5.5 V) and integrated fault protection are prioritized over lowest rON |
| ADG736BRMZ-REEL7 | rON = 0.4 Ω at 3 V; -60 dB OIRR; 10-pin MSOP package | Lower ESD rating (1500 V HBM) and higher leakage (>20 nA at 85 °C) reduce robustness in consumer handhelds | Suitable for industrial instrumentation where temperature stability and long-term reliability outweigh ESD margin needs |
Compared with MAX4685EUB+T and ADG736BRMZ-REEL7, the DG2535DQ-T1-E3 delivers superior on-resistance (0.35 Ω), isolation (-69 dB), and ESD protection (>2000 V), making it optimal for space-constrained, battery-sensitive audio routing where signal fidelity and handling robustness are critical.

FAQ
What is the maximum analog signal voltage range supported by the DG2535DQ-T1-E3?
The DG2535DQ-T1-E3 supports analog signals from 0 V to V+, where V+ ranges from 1.8 V to 6 V. Absolute maximum ratings specify that signals on NO, NC, or COM pins must not exceed V+ + 0.3 V or fall below -0.3 V relative to GND. This allows full-rail operation in 3 V systems and safe interfacing with 1.8 V logic-controlled audio paths without clamping distortion.
Does the DG2535DQ-T1-E3 require external pull-up or pull-down resistors on its IN1 and IN2 control pins?
No, the DG2535DQ-T1-E3 does not require external biasing on IN1 or IN2. Its input thresholds are specified as VINH = 1.4 V (min) and VINL = 0.5 V (max), ensuring reliable recognition of standard 1.8 V CMOS logic levels. Input leakage remains below 1 µA across temperature, eliminating need for external resistors in typical microcontroller-driven applications.
How does the DG2535DQ-T1-E3 achieve latch-up immunity, and what is its rated latch-up current?
The DG2535DQ-T1-E3 incorporates an epitaxial layer in its high-density low-voltage CMOS process to prevent latch-up, and is rated for >300 mA latch-up current per JESD78. This design ensures robust operation during transient overcurrent events such as hot-plug insertion or accidental shorts in portable device signal chains, without requiring external current-limiting circuitry.
Can the DG2535DQ-T1-E3 be used in bidirectional signal paths, and what is its channel conduction symmetry?
Yes, the DG2535DQ-T1-E3 supports fully bidirectional analog signal flow in both ON states. When conducting, all switch elements (NO1↔COM1, NO2↔COM2, NC1↔COM1, NC2↔COM2) exhibit symmetric on-resistance and capacitance characteristics - verified by identical rON, CNO(on), and CNC(on) values in datasheet specifications - enabling use in AC-coupled audio, differential signaling, and sensor interface applications.
What is the thermal derating behavior of the DG2535DQ-T1-E3 above 70 °C ambient temperature?
The DG2535DQ-T1-E3 has a thermal derating factor of 4.0 mW/°C above 70 °C ambient for its MSOP-10 package. With a maximum power dissipation of 320 mW at ≤70 °C, this means usable power drops linearly to ~280 mW at 80 °C. Designers must ensure junction temperature stays within -40 °C to +85 °C operating range using appropriate PCB copper area and airflow in sealed enclosures.
