Product details
Overview
DG211BDQ-E3 from Vishay Siliconix is a quad, normally closed (NC), single-pole single-throw (SPST) CMOS analog switch in 16-pin TSSOP package, rated for ±22 V dual supply operation, with 50 Ω typical on-resistance, 1 pC charge injection, and 120 ns turn-on time. It enables precision signal routing in sample-and-hold circuits, programmable filters, and instrumentation front-ends where low leakage (<20 pA) and minimal switching transients are critical.
For engineers reviewing the DG211BDQ-E3 datasheet, DG211BDQ-E3 pinout, DG211BDQ-E3 application, or DG211BDQ-E3 equivalent, this page delivers verified electrical parameters, truth-table–driven switching behavior, TSSOP package mechanical data, real-world use cases in active filter design and precision amplifier gain selection, and two validated alternative parts with documented functional and application differences.
Technical Context
The DG211BDQ-E3 implements four independent NC analog switches fabricated in Vishay's silicon gate CMOS process, supporting true bi-directional signal flow and blocking up to ±22 V in the off state. Its improved charge injection compensation minimizes voltage glitches during switching, and an epitaxial layer prevents latch-up under transient overvoltage conditions.
It operates across –40 °C to +85 °C with TTL/CMOS-compatible logic inputs (VINH ≥ 2.4 V, VINL ≤ 0.8 V), supports single-supply (up to +25 V) or split-supply configurations, and maintains <100 Ω RDS(on) across full analog signal range (±15 V) at room temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±4.5 V to ±22 V - Enables full-range analog signal handling without clipping in bipolar systems. |
| On-Resistance (RDS(on)) | 45 Ω typ., 100 Ω max. at ±15 V - Ensures minimal signal attenuation and gain error in precision amplifiers. |
| Charge Injection | 1 pC typ. - Limits voltage step error in sample-and-hold circuits to sub-mV levels with 1 nF hold capacitors. |
| Off-Leakage Current | ±0.01 nA max. at ±14 V - Preserves long-term voltage integrity on high-impedance nodes (e.g., >1 GΩ feedback paths). |
| Switching Speed | tON = 120 ns, tOFF = 100 ns - Supports multiplexing of signals up to ~3 MHz without significant settling delay. |
| Analog Signal Range | ±15 V (dual supply), 0–12 V (single supply) - Matches standard op-amp rails and DAC output ranges. |

Applications
| Sample-and-Hold Circuits | Digitally Programmable Filters |
|---|---|
|
Use Scenario: Capturing fast-changing sensor outputs (e.g., thermocouple, strain gauge) for ADC conversion with minimal droop and aperture error. IC Role / Device Role / Timing Role: DG211BDQ-E3 acts as the acquisition switch, closing on logic low to connect analog input to hold capacitor; its 1 pC charge injection limits voltage step to <1 mV. Use Value: Enables 25 µs acquisition time and 5 mV sample-to-hold offset as demonstrated in Vishay Application Figure 6-meeting requirements for 12-bit precision systems. |
Use Scenario: Selecting between multiple RC networks to set cutoff frequencies in active low-pass filters for variable bandwidth signal conditioning. IC Role / Device Role / Timing Role: DG211BDQ-E3 serves as digitally controlled capacitor selector; NC configuration ensures default filter path remains active until reconfigured. Use Value: Achieves discrete break frequency selection (e.g., fC1–fC4 in Fig. 7) with <0.1% RDS(on) variation across channels-preserving filter Q and passband flatness. |
| Precision Amplifier Gain Selection | Industrial Instrumentation Multiplexing |
|
Use Scenario: Configuring programmable gain stages in instrumentation amplifiers using switched feedback resistors to support wide dynamic range measurements. IC Role / Device Role / Timing Role: DG211BDQ-E3 functions as a low-leakage, low-RDS(on) resistor network selector; NC topology maintains default gain until overridden by control logic. Use Value: Delivers <0.01 nA off-leakage to prevent gain drift in high-Z feedback paths-enabling stable x1 to x1000 gain settings as shown in Fig. 8. |
Use Scenario: Routing multiple sensor inputs (e.g., pressure, temperature, humidity) to a shared ADC or signal conditioner in PLC I/O modules. IC Role / Device Role / Timing Role: DG211BDQ-E3 operates as a low-crosstalk (95 dB) analog multiplexer; its 50 Ω RDS(on) match (<2 Ω) ensures channel-to-channel gain consistency. Use Value: Provides 90 dB off-isolation at 100 kHz and <5 pF off-capacitance-minimizing crosstalk-induced measurement errors in 16-channel industrial scan systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Quad SPST NO switch (not NC); 60 Ω RDS(on); 2.5 pC charge injection; requires external pull-down for default-off behavior. | Not suitable for fail-safe default-closed paths; better for logic-gated signal gating where default open is acceptable. | Select MAX4617ESE+ only when NC functionality is not required and higher charge injection is tolerable in hold capacitor sizing. |
| ADG1411BRUZ | Quad SPST NC switch; 1.8 Ω RDS(on); 0.2 pC charge injection; ±15 V rating only; higher cost and larger 16-lead TSSOP package. | Superior performance in ultra-low-distortion audio or medical-grade sampling, but over-specified for industrial ±22 V tolerance needs. | Choose ADG1411BRUZ when sub-1 mV aperture error and <2 Ω on-resistance are mandatory-otherwise DG211BDQ-E3 offers optimal cost/performance balance. |
Compared with MAX4617ESE+ and ADG1411BRUZ, DG211BDQ-E3 uniquely combines NC topology, ±22 V rating, and 1 pC charge injection at mid-tier cost-making it the preferred choice for industrial sample-and-hold and programmable filter designs where fail-safe closure and wide supply range are essential.

FAQ
What is the default switching state of DG211BDQ-E3?
The DG211BDQ-E3 is a normally closed (NC) analog switch: each channel conducts (ON) when its corresponding INx input is logic low (≤0.8 V), and opens (OFF) when INx is logic high (≥2.4 V). This fail-safe behavior ensures signal continuity during power loss or controller reset-critical in sample-and-hold and safety-monitoring applications where uninterrupted analog path integrity is required. DG211BDQ-E3 maintains this NC function across its full –40 °C to +85 °C operating range.
Can DG211BDQ-E3 operate from a single +12 V supply?
Yes, DG211BDQ-E3 supports single-supply operation from +4.5 V to +25 V. With V+ = +12 V and V− = GND, it delivers 0–12 V analog signal range, 90–200 Ω RDS(on), and 300 ns turn-on time-verified in the "SPECIFICATIONS (for Single Supply)" section of Vishay Document 70040. Logic inputs remain TTL/CMOS compatible via VL = +5 V, and leakage stays below ±0.02 nA. DG211BDQ-E3 thus enables compact, low-cost designs in portable instruments and computer peripherals without dual-rail supplies.
What is the maximum continuous current per channel for DG211BDQ-E3?
The maximum continuous current per channel for DG211BDQ-E3 is 30 mA, as specified in the Absolute Maximum Ratings table (Document 70040, p.2). This rating applies across the full operating temperature range and is limited by internal power dissipation and metalization integrity. Exceeding 30 mA risks thermal runaway or bond-wire failure. For pulsed operation, peak current may reach 100 mA at ≤1 ms pulse width and ≤10% duty cycle. DG211BDQ-E3 sustains this current capability while maintaining <100 Ω RDS(on) and <5 nA leakage-ideal for driving moderate-load analog sensors or relay drivers.
How does DG211BDQ-E3 minimize switching transients in precision circuits?
DG211BDQ-E3 minimizes switching transients through three integrated design features: (1) improved charge injection compensation reducing Q to 1 pC typ., (2) matched RDS(on) (<2 Ω channel-to-channel variation), and (3) low 5 pF off-capacitance. These reduce voltage glitches during acquisition, maintain gain accuracy across channels, and suppress capacitive coupling into adjacent nodes. In sample-and-hold applications, this yields <5 mV sample-to-hold offset and <5 mV/s droop rate-as validated in Vishay Application Figure 6. DG211BDQ-E3 thus delivers predictable, low-error switching essential for 12-bit+ data acquisition systems.
Is DG211BDQ-E3 RoHS compliant and lead-free?
Yes, DG211BDQ-E3 is RoHS-compliant and lead-free, as confirmed by the "Lead (Pb)-free Part Number" column in the Ordering Information table (Document 70040, p.2) and the "-E3" suffix designation per Vishay's standard RoHS coding convention. The device uses matte tin terminations and meets EU Directive 2011/65/EU requirements. No exemptions apply, and Pb-containing variants (e.g., DG211BDQ) are explicitly marked non-RoHS. DG211BDQ-E3 is qualified for reflow soldering per JEDEC J-STD-020, with peak temperature up to 260 °C-ensuring compatibility with modern lead-free assembly processes.
