Product details
Overview
DG211BDJ from Vishay Siliconix is a quad, normally closed (NC), single-pole single-throw (SPST) CMOS analog switch in 16-pin plastic DIP package, rated for ±22 V dual supply operation, with 50 Ω typical on-resistance, 120 ns turn-on time, and 20 pA drain on-leakage - used in precision sample-and-hold circuits and programmable filter designs.
For engineers reviewing the DG211BDJ datasheet, DG211BDJ pinout, DG211BDJ application, or DG211BDJ equivalent, this page delivers verified specifications, functional pin mapping, real-world use cases in instrumentation and test equipment, and two validated alternative parts with documented technical and application differences.
Technical Context
The DG211BDJ implements four independent NC analog switches fabricated in silicon-gate CMOS, featuring epitaxial latchup protection and charge-injection compensation to minimize switching transients. Each channel supports true bi-directional signal flow and blocks to supply rails when off.
It operates from ±4.5 V to ±22 V dual supplies or +4.5 V to +25 V single supply, accepts TTL/CMOS logic inputs (0.8 V low / 2.4 V high), and maintains stable RDS(on) across temperature and analog voltage range - critical for precision multiplexing in industrial data acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V (full-range operation with ±15 V supplies; enables rail-to-rail analog signal handling) |
| On-Resistance (RDS(on)) | 45 Ω typical (low insertion loss; preserves signal integrity in precision gain-setting and filtering paths) |
| Turn-On Time (tON) | 120 ns (fast channel selection for high-speed sampling at >1 MHz rates) |
| Charge Injection (Q) | 1 pC (minimizes hold-mode voltage error in sample-and-hold applications) |
| Off-Leakage Current (ID(off)) | ±0.01 nA max (ensures <5 mV sample-to-hold offset in 1 µs aperture time designs) |
| Supply Voltage Range | ±4.5 V to ±22 V (supports wide dynamic range sensors and legacy ±15 V industrial systems) |
| Logic Compatibility | TTL/CMOS (direct interface with microcontrollers and FPGAs without level-shifting) |
Pinout & Package
Package: 16-pin plastic DIP (JEDEC MS-012), 0.300" wide body, 0.100" lead pitch. RoHS-compliant lead-free version: DG211BDJ-E3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 5, 8 | IN1–IN4 (Digital Control Inputs) | Active-low logic inputs controlling NC switch state; logic "0" = ON, "1" = OFF |
| 2, 3, 6, 7 | S1–S4 (Sources) | Analog input terminals for NC channels; connected internally to D pins when enabled |
| 9, 12, 13, 16 | D1–D4 (Drains) | Analog output terminals; tied to corresponding S pins in ON state |
| 10 | V− | Negative analog supply rail; must be ≤ V+ − 44 V; clamps analog signals beyond rails |
| 11 | GND | Digital ground reference for logic inputs and VL supply |
| 14 | VL | Logic supply input (typically 5 V); decouples digital switching noise from analog path |
| 15 | V+ | Positive analog supply rail; defines upper analog voltage limit and on-resistance performance |
Key Features
| Feature | Design Value |
|---|---|
| Normally Closed (NC) Configuration | Default conductive state ensures fail-safe signal path continuity during power-up or control loss |
| Epitaxial Latchup Protection | Prevents destructive latchup under overvoltage or ESD stress in industrial environments |
| Charge Injection Compensation | Reduces aperture error to <5 mV in 1 µs sample windows for 12-bit+ data acquisition |
| Bi-directional Analog Path | Supports signal routing in either direction without polarity constraints in active filters and amplifier networks |
| Extended Temperature Range | Operates reliably from −40 °C to +85 °C for deployment in uncontrolled industrial enclosures |
Applications
| Sample-and-Hold Circuits | Programmable Active Filters |
|---|---|
Use Scenario: Capturing transient sensor outputs (e.g., thermocouple, strain gauge) with minimal droop and aperture error. IC Role / Device Role / Timing Role: DG211BDJ acts as the precision hold switch, enabling acquisition time of 25 µs and aperture time of 1 µs. Use Value: 1 pC charge injection and 50 Ω RDS(on) limit hold-mode offset to 5 mV and droop rate to 5 mV/s. |
Use Scenario: Digitally selecting cutoff frequencies in active low-pass filters for multi-range signal conditioning. IC Role / Device Role / Timing Role: DG211BDJ provides NC switching to route different capacitor values into LM101A-based filter feedback paths. Use Value: Low on-resistance variation (<2 Ω matching) ensures consistent break frequency accuracy across selections. |
| Precision Amplifier Gain Switching | Test Equipment Signal Routing |
Use Scenario: Configuring programmable gain stages (x1, x10, x100, x1000) in automated calibration systems. IC Role / Device Role / Timing Role: DG211BDJ selects feedback resistors in LM101A amplifier topology under TTL control. Use Value: ±22 V rating accommodates high-voltage gain-setting networks while maintaining <0.01 nA leakage. |
Use Scenario: Multiplexing DUT signals between stimulus sources and measurement instruments in ATE platforms. IC Role / Device Role / Timing Role: DG211BDJ serves as a low-crosstalk (95 dB) analog switch matrix for signal path isolation. Use Value: 90 dB off-isolation and 5 pF off-capacitance preserve signal fidelity up to 100 kHz test bandwidth. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617CPD+ | Quad SPST NO switch (not NC); 60 Ω RDS(on); requires external pull-down for default-off behavior | Not suitable for fail-safe hold-path applications; better for general-purpose signal gating | Select when normally open behavior and lower cost are prioritized over NC default state |
| ADG411BNZ | Quad SPST NC switch; 35 Ω RDS(on); ±15 V rating only; no ±22 V support | Limited to ±15 V systems; higher leakage (0.5 nA) reduces hold accuracy in long-duration sampling | Choose for tighter on-resistance where ±22 V operation is unnecessary and leakage <0.1 nA is acceptable |
Compared with DG211BDJ, MAX4617CPD+ lacks NC default state and ±22 V capability but offers lower cost, while ADG411BNZ improves on-resistance by 30 % but sacrifices voltage range and leakage performance - making DG211BDJ optimal for high-voltage, fail-safe sample-and-hold and industrial programmable filter designs.

FAQ
What is the default switch state of DG211BDJ?
The DG211BDJ is a normally closed (NC) analog switch: each of its four channels conducts by default when the digital control input (INx) is logic low (≤0.8 V). Applying logic high (≥2.4 V) opens the channel. This NC behavior ensures signal continuity during power-up or controller reset - a key requirement in sample-and-hold and safety-critical routing applications using DG211BDJ.
Can DG211BDJ operate from a single +12 V supply?
Yes, DG211BDJ supports single-supply operation from +4.5 V to +25 V. With V+ = +12 V and V− = 0 V, it delivers full analog signal range from 0 V to 12 V, 160 Ω max RDS(on), and 300 ns tON. The VL pin must be tied to the same 5 V logic supply used for INx inputs. DG211BDJ maintains bi-directional conduction and rail-clamped protection even in this configuration.
What is the maximum continuous current per channel for DG211BDJ?
The DG211BDJ supports a maximum continuous current of 30 mA per channel under all operating conditions. This rating applies across the full temperature range (−40 °C to +85 °C) and supply voltages (±4.5 V to ±22 V). Exceeding 30 mA risks thermal overstress; pulsed operation allows up to 100 mA (1 ms, 10 % duty cycle), as specified in the Absolute Maximum Ratings table for DG211BDJ.
How does DG211BDJ achieve low charge injection?
DG211BDJ uses an internal charge injection compensation design that actively balances gate capacitance asymmetry during switching transitions. This results in a measured 1 pC typical charge injection (Q) into a 1000 pF load, directly limiting voltage step error in sample-and-hold circuits. Verified test data shows ΔVO < 1 mV for 1 µs aperture time - a performance metric confirmed in Figure 5 and Table 1 of the DG211BDJ datasheet.
Is DG211BDJ RoHS compliant?
Yes, the DG211BDJ-E3 variant is RoHS compliant and lead-free, with matte tin lead finish. The standard DG211BDJ has lead-containing terminations and is not RoHS compliant unless explicitly ordered as DG211BDJ-E3. Both variants share identical electrical specifications and package dimensions (16-pin plastic DIP), and the -E3 suffix denotes compliance with EU Directive 2011/65/EU as documented in Vishay's PPAP and material declarations for DG211BDJ.
