Product details
Overview
DG2011DXA-T1-E3 from Vishay Siliconix is a low-voltage, single-pole/double-throw (SPDT) CMOS analog switch in SC-89 (SOT-666) package, featuring 1.8 Ω on-resistance at 2.7 V, <10 pC charge injection, and guaranteed break-before-make operation. It serves as a bidirectional signal path selector in portable battery-powered systems requiring minimal board space and high analog fidelity.
For engineers reviewing the DG2011DXA-T1-E3 datasheet, DG2011DXA-T1-E3 pinout, DG2011DXA-T1-E3 application, or DG2011DXA-T1-E3 equivalent, key selection criteria include low-voltage logic compatibility (1.8–5.5 V supply), sub-2 Ω rON stability across temperature, and SC-89 footprint constraints for high-density PCB layouts.
Technical Context
The DG2011DXA-T1-E3 implements a monolithic CMOS SPDT switch architecture with epitaxial latchup protection and rail-to-rail analog signal handling (0 to V+). Its control logic is compatible with 1.8 V CMOS thresholds (VINH = 1.6 V min at V+ = 3 V), and it guarantees break-before-make timing of ≤16 ns at 3 V.
Dynamic performance is characterized by 45–77 ns turn-on time and 29–62 ns turn-off time (V+ = 3 V, RL = 300 Ω, CL = 35 pF), while off-isolation exceeds –62 dB and crosstalk remains below –68 dB at 1 MHz - enabling precision signal routing in mixed-signal data acquisition paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - supports direct interface with Li-ion battery rails and low-power microcontrollers without level shifting. |
| On-Resistance (rON) | 1.8 Ω typ. at 2.7 V - ensures <10 mV voltage drop at 50 mA signal current, preserving ADC/DAC accuracy. |
| Charge Injection | 2 pC typ. at V+ = 3 V - minimizes sampling error in sample-and-hold and switched-capacitor circuits. |
| Off-Isolation (OIRR) | –62 dB at 1 MHz - suppresses coupling between NC/NO paths during signal switching in RF-adjacent analog stages. |
| Turn-On/Off Time | 45 ns / 29 ns typ. at 3 V - enables >10 MHz switching rates in multiplexed sensor interfaces. |
| Logic Compatibility | VINH = 1.6 V min, VINL = 0.4 V max at V+ = 3 V - interoperates with 1.8 V I/O domains without external translators. |
| Package | SC-89 (SOT-666), 1.6 × 1.6 mm² - reduces PCB area by ~40% vs. SC-70, critical for ultra-compact handheld designs. |
Pinout & Package
SC-89 (SOT-666) surface-mount package with 6-pin configuration, 0.65 mm pitch, and lead (Pb)-free matte tin terminations (RoHS-compliant per -E3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NO) | Normally Open switch terminal | Connects to COM only when IN = logic high; carries full analog signal range (0 to V+). |
| 2 (COM) | Common analog port | Central bidirectional signal path; must remain within V+ and GND; clamped by internal diodes if exceeded. |
| 3 (NC) | Normally Closed switch terminal | Connects to COM only when IN = logic low; shares same voltage/current specs as NO. |
| 4 (GND) | Ground reference | Analog and digital ground return; must be low-impedance to minimize noise coupling into analog path. |
| 5 (V+) | Positive supply | Single supply rail powering both analog switch core and control logic; supports 1.8–5.5 V operation. |
| 6 (IN) | Digital control input | CMOS-compatible logic input; active-high control toggles COM between NC (IN = 0) and NO (IN = 1). |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | Ensures no momentary short between NC and NO during state transition, preventing signal glitches in sensitive measurement paths. |
| Low on-resistance flatness (±0.5 Ω) | Maintains consistent rON across analog input voltage (0–V+), critical for linearity in audio and instrumentation amplifiers. |
| Sub-10 pC charge injection | Reduces settling error in capacitor-coupled circuits, enabling accurate DC-coupled sampling without large hold capacitors. |
| Rail-to-rail analog signal range | Supports full V+ to GND swing on all analog pins (COM/NO/NC), eliminating need for external biasing in single-supply systems. |
| Epitaxial latchup protection | Prevents destructive latchup under transient overvoltage or ESD events, enhancing reliability in portable consumer electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Texas Instruments TS5A23157DBVR | rON = 0.9 Ω typ. at 3 V; higher supply current (1 µA vs. 0.01 µA); SC-70-6 package (2.0 × 2.1 mm²) | Better rON but larger footprint and higher quiescent power - suitable where size is less constrained than battery life. | Select DG2011DXA-T1-E3 for ultra-low power and minimal PCB area; choose TS5A23157DBVR only if sub-1 Ω rON justifies 2.5× larger footprint. |
| Analog Devices ADG819BRMZ | rON = 0.5 Ω typ. at 3 V; requires 1.65–5.5 V supply; MSOP-8 package (3.0 × 3.0 mm²); no guaranteed BBM | Lower rON but larger package and unguaranteed break-before-make - risk of signal shorting in safety-critical paths. | DG2011DXA-T1-E3 is preferred for battery-operated medical or portable test gear where BBM assurance and SC-89 size are mandatory. |
Compared with TS5A23157DBVR and ADG819BRMZ, DG2011DXA-T1-E3 delivers optimal trade-off of ultra-small footprint (1.6 × 1.6 mm²), guaranteed break-before-make, and nanoamp-level supply current - making it uniquely suited for space- and power-constrained portable instrumentation where signal integrity and reliability are non-negotiable.

FAQ
What is the maximum analog signal voltage range supported by the DG2011DXA-T1-E3?
The DG2011DXA-T1-E3 supports a full rail-to-rail analog signal range from 0 V to V+, where V+ can be set between 1.8 V and 5.5 V. Signals on the COM, NO, or NC pins exceeding V+ are clamped by internal diodes, so the absolute maximum analog voltage is limited to V+ + 0.3 V per Absolute Maximum Ratings. This allows seamless integration in single-supply 1.8 V, 2.7 V, or 3.3 V systems without external biasing.
Does the DG2011DXA-T1-E3 guarantee break-before-make timing, and what is its typical value?
Yes, the DG2011DXA-T1-E3 guarantees break-before-make (BBM) operation, a critical feature for preventing signal shorts during switching. At V+ = 3 V, the typical BBM time is 1 ns, with a maximum of 16 ns across the full –40 °C to +85 °C operating temperature range. This specification is verified in the datasheet's Dynamic Characteristics table and confirmed by functional block diagram timing analysis.
What is the on-resistance (rON) of the DG2011DXA-T1-E3 at 2.0 V supply, and how does it vary with analog voltage?
At V+ = 2.0 V, the DG2011DXA-T1-E3 has a maximum on-resistance of 5.5 Ω (over temperature), with a typical value of 3.5 Ω. As shown in the "rON vs. VCOM and Supply Voltage" characteristic curve, rON remains relatively flat across the analog input range (0 to V+), varying by less than ±0.5 Ω - ensuring consistent signal attenuation in precision analog paths regardless of signal level.
Is the DG2011DXA-T1-E3 RoHS-compliant, and what does the "-E3" suffix signify?
Yes, the DG2011DXA-T1-E3 is RoHS-compliant. The "-E3" suffix explicitly denotes lead (Pb)-free terminations using 100 % matte tin plating, as defined in Vishay's ordering nomenclature. This designation replaces Pb-containing versions (e.g., DG2011DX-T1) and meets EU RoHS Directive 2011/65/EU requirements without exemptions.
Can the DG2011DXA-T1-E3 operate reliably at 1.8 V supply, and what logic levels are compatible?
Yes, the DG2011DXA-T1-E3 is fully specified and guaranteed for operation down to 1.8 V supply. At this voltage, the input high threshold (VINH) is 1.5 V minimum and input low threshold (VINL) is 0.4 V maximum - making it directly compatible with 1.8 V CMOS logic families without level-shifting circuitry. This capability is confirmed in the "Digital Control" section of the datasheet.
