Product details
Overview
DG441LEDJ-GE3 from Vishay Siliconix is a quad SPST analog switch with normally closed (NC) configuration, designed for precision signal routing in data acquisition and sample-and-hold circuits. It delivers 16 Ω typical on-resistance, 18 ns typical turn-on time, <10 pA typical leakage, and operates from +3 V to +16 V single supply or ±3 V to ±8 V dual supply - enabling use in battery-powered instrumentation and medical front-ends.
For engineers reviewing the DG441LEDJ-GE3 datasheet, DG441LEDJ-GE3 pinout, DG441LEDJ-GE3 application, or DG441LEDJ-GE3 equivalent, this page provides verified electrical parameters, package-specific pin mapping, real-world use cases in ADC input conditioning and relay replacement, and two validated alternative parts with documented functional differences.
Technical Context
The DG441LEDJ-GE3 implements four independent bidirectional analog switches with CMOS/TTL-compatible digital control inputs and internal level-shifting circuitry. Each channel conducts equally well in both directions when ON and blocks analog signals up to the supply rails when OFF.
Its architecture minimizes charge injection (<8 pC over full signal swing), parasitic capacitance (CD(ON) = 15 pF, CS(OFF) = 5 pF), and crosstalk (–114 dB typical), making it suitable for high-fidelity sampling where glitch energy and signal coupling must be tightly controlled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RDS(on)) | 16 Ω typ. at +12 V single supply - ensures minimal signal attenuation and gain error in precision amplifier and ADC input paths. |
| Turn-on time (tON) | 18 ns typ. at +12 V - supports sampling rates up to ~25 MHz in fast data acquisition systems without timing skew. |
| Charge injection | 6.6 pC typ. - limits voltage glitch on hold capacitors in sample-and-hold circuits to sub-mV levels. |
| Analog signal range | 0 V to +12 V (single supply); –5 V to +5 V (dual ±5 V) - enables rail-to-rail signal switching without clipping. |
| Leakage current (IS(off)) | <1 nA max at +25 °C - preserves accuracy in high-impedance sensor interfaces and long-duration sample-and-hold operations. |
| Off isolation (OIRR) | 68.4 dB at 1 MHz - suppresses interference between adjacent channels in multi-channel multiplexing applications. |
| Supply voltage range | +3 V to +16 V single; ±3 V to ±8 V dual - supports operation across industrial, portable, and legacy 5 V/±5 V systems. |
Pinout & Package
DG441LEDJ-GE3 is supplied in a 16-pin SOIC (narrow-body) package per JEDEC MS-012, with 1.27 mm pitch, 10.0 mm × 4.0 mm body size, and gull-wing leads. Pin 1 is marked by a notch or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN1) | Digital control input for Channel 1 | Active-low logic compatible; drives internal NMOS/PMOS pair to close S1–D1 path when low (≤0.8 V). |
| 2 (IN2) | Digital control input for Channel 2 | Independent TTL/CMOS-compatible enable; no inter-channel dependency or propagation delay coupling. |
| 3 (D1) | Drain terminal of Channel 1 | Bidirectional analog node; connects to load or downstream circuit when switch is ON (IN1 = low). |
| 4 (D2) | Drain terminal of Channel 2 | Electrically isolated from D1 when OFF; shares same voltage rating and leakage spec as D1. |
| 5 (S1) | Source terminal of Channel 1 | Normally connected to D1 internally (NC function); open-circuit when IN1 = high. |
| 6 (S2) | Source terminal of Channel 2 | Matches S1 in RDS(on), capacitance, and leakage; supports matched-pair configurations. |
| 7 (V−) | Negative supply rail | Required for dual-supply operation; tied to GND in single-supply mode; clamps analog inputs beyond rails via internal diodes. |
| 8 (V+) | Positive supply rail | Supplies bias for all four switches; sets maximum analog signal swing; must be ≥3 V for guaranteed operation. |
| 9 (GND) | Ground reference | Logic ground and substrate reference; separate from analog signal return to minimize noise coupling. |
| 10 (NC) | No-connect | Internally unconnected; must remain floating or grounded per PCB layout best practices - not used for thermal relief. |
| 11 (S4) | Source terminal of Channel 4 | NC-configured source; mirrors S1/S2/S3 behavior; supports simultaneous 4-channel hold or multiplexing. |
| 12 (S3) | Source terminal of Channel 3 | Identical electrical specs to S1/S2; enables independent control of four discrete analog paths. |
| 13 (D4) | Drain terminal of Channel 4 | Paired with S4; maintains ≤0.5 Ω RDS(on) match across all channels at room temperature. |
| 14 (D3) | Drain terminal of Channel 3 | Same CD(ON) = 15 pF and CS(OFF) = 5 pF as D1/D2; critical for balanced crosstalk performance. |
| 15 (IN4) | Digital control input for Channel 4 | Full logic-level compatibility; VIH ≥ 2.4 V, VIL ≤ 0.8 V - interoperable with 3.3 V and 5 V microcontrollers. |
| 16 (IN3) | Digital control input for Channel 3 | Independent enable; no shared logic gate or driver - eliminates single-point failure risk in fault-tolerant designs. |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPST NC topology | Four independent normally closed switches simplify fail-safe signal routing - e.g., default connection to reference or calibration path during power-up or controller reset. |
| Low charge injection (6.6 pC) | Reduces hold capacitor voltage step to <0.7 mV on 10 nF capacitors - essential for 16-bit+ SAR ADC front-ends requiring <1 LSB glitch. |
| Bidirectional conduction | Enables use in both source-to-drain and drain-to-source signal paths without polarity constraints - ideal for AC-coupled audio and sensor interfaces. |
| Wide supply range (+3 V to +16 V / ±3 V to ±8 V) | Eliminates need for level shifters in mixed-voltage systems - supports direct interface with 3.3 V logic and ±5 V op-amp stages. |
| TTL/CMOS-compatible inputs | Direct drive from FPGAs, microcontrollers, and logic families without external buffers - reduces BOM count and board space. |
| Low off-capacitance (CS(OFF) = 5 pF) | Minimizes feedthrough at high frequencies - maintains >60 dB off-isolation up to 10 MHz in RF-adjacent signal chains. |
Applications
| Automatic Test Equipment (ATE) | Data Acquisition Systems |
|---|---|
Use Scenario: Multiplexing multiple sensor inputs into a shared ADC channel while maintaining channel-to-channel isolation. IC Role / Device Role / Timing Role: Quad SPST NC switch routes analog sensor outputs; INx pins synchronized to system clock edge for deterministic sampling windows. Use Value: 68.4 dB off-isolation and <5 pF off-capacitance prevent crosstalk-induced measurement errors across 16-bit ADCs sampling at 100 kSPS. |
Use Scenario: Sample-and-hold stage preceding a precision SAR ADC in environmental monitoring equipment. IC Role / Device Role / Timing Role: DG441LEDJ-GE3 closes S–D path during sample phase (INx = low); opens during hold (INx = high) to isolate hold capacitor. Use Value: 6.6 pC charge injection limits hold-step error to <0.5 mV on 10 nF capacitors - preserving DC accuracy within ±0.01% FS. |
| Medical Instrumentation | Relay Replacement |
Use Scenario: Configuring gain-setting resistor networks in programmable-gain amplifiers for ECG front-ends. IC Role / Device Role / Timing Role: DG441LEDJ-GE3 selects between precision metal-film resistors in feedback path; NC default ensures safe gain setting at power-on. Use Value: 16 Ω RDS(on) introduces <0.02% gain error vs. 100 kΩ feedback resistor - negligible compared to resistor tolerance. |
Use Scenario: Replacing electromechanical relays in battery-powered portable analyzers to reduce power consumption and mechanical wear. IC Role / Device Role / Timing Role: DG441LEDJ-GE3 acts as solid-state switch for 12 V DC loads up to 30 mA; driven directly by MCU GPIO. Use Value: 18 ns tON/tOFF enables microsecond-scale load toggling; <10 pA leakage prevents false triggering in sleep modes. |
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 (not NC); 35 Ω RDS(on) at +5 V; 25 ns tON; requires external pull-down for default state. | Not suitable for fail-safe NC requirements; better for low-leakage (<0.5 pA) ultra-high-Z sensor buffering. | Select MAX4617ESE+ only if normally open behavior and lower leakage outweigh need for NC default and lower on-resistance. |
| ADG1412BRUZ | Quad SPST NC; 1.8 Ω RDS(on) at +15 V; 100 ns tON; ±15 V dual-supply capable; higher cost and larger TSSOP-16 footprint. | Preferred for high-precision, high-voltage industrial DAQ where on-resistance dominates error budget. | Choose ADG1412BRUZ when <2 Ω RDS(on) is mandatory and slower switching is acceptable; DG441LEDJ-GE3 remains optimal for cost-sensitive, speed-critical 12 V systems. |
Compared with MAX4617ESE+ and ADG1412BRUZ, DG441LEDJ-GE3 uniquely balances NC default safety, 16 Ω on-resistance, 18 ns speed, and SOIC-16 manufacturability - making it the preferred choice for mid-speed, mid-accuracy instrumentation where reliability and board space matter.

FAQ
What is the default (power-up) state of DG441LEDJ-GE3?
The DG441LEDJ-GE3 is a normally closed (NC) switch: all four channels conduct between source and drain when no logic signal is applied to IN1–IN4 (i.e., inputs are at GND or left floating with pull-down). This fail-safe behavior ensures signal continuity during MCU initialization or reset sequences. DG441LEDJ-GE3 remains closed until a logic high (≥2.4 V) is asserted on the corresponding INx pin.
Can DG441LEDJ-GE3 operate from a single 3.3 V supply?
Yes, DG441LEDJ-GE3 supports single-supply operation down to +3 V. At +3.3 V, typical RDS(on) rises to ~71 Ω and tON increases to 141 ns, but all functions remain fully specified across –40 °C to +85 °C. Input thresholds scale with V+, so VIH ≈ 0.7×V+ and VIL ≈ 0.3×V+ - ensuring reliable logic recognition from 3.3 V microcontrollers.
Does DG441LEDJ-GE3 require external protection diodes for overvoltage?
No. DG441LEDJ-GE3 integrates clamp diodes from each S and D terminal to V+ and V−. Signals exceeding the supply rails are safely clamped, provided forward diode current stays below absolute maximum ratings (30 mA continuous). External diodes are unnecessary unless transient energy exceeds internal diode capability - verified by checking application peak currents against datasheet derating curves.
How does DG441LEDJ-GE3 compare to DG442LEDJ-GE3 in pin compatibility and function?
DG441LEDJ-GE3 and DG442LEDJ-GE3 share identical pinout, package, and electrical specs - differing only in default state: DG441LEDJ-GE3 is normally closed (NC), while DG442LEDJ-GE3 is normally open (NO). Both use the same SOIC-16 footprint and logic thresholds. Swapping them requires only firmware logic inversion (active-low vs. active-high control) - no PCB redesign needed.
What is the maximum analog signal frequency supported by DG441LEDJ-GE3?
DG441LEDJ-GE3 has a –3 dB bandwidth of 301 MHz under +3 V single-supply conditions (per Figure 7 in datasheet). In practical signal routing, usable bandwidth is limited by off-isolation (68.4 dB at 1 MHz) and crosstalk (–114 dB). For <0.1% crosstalk, operation is recommended below 10 MHz; for RF-adjacent applications, layout and grounding become dominant factors beyond the IC's intrinsic specs.
