Product details
Overview
DG441LEDQ-GE3 from Vishay Siliconix is a quad single-pole-single-throw (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, and <8 pC charge injection over full signal swing - enabling low-error switching of analog signals up to ±5 V or 12 V supply rails.
For engineers reviewing the DG441LEDQ-GE3 datasheet, DG441LEDQ-GE3 pinout, DG441LEDQ-GE3 application, or DG441LEDQ-GE3 equivalent, key selection criteria include its NC logic behavior, TSSOP-16 package compatibility, low leakage (<10 pA typ.), dual-supply operation (±3 V to ±8 V), and suitability for medical instrumentation and battery-powered systems requiring minimal switching glitch.
Technical Context
The DG441LEDQ-GE3 implements four independent bidirectional analog switches with complementary CMOS control architecture, supporting both single-supply (3 V to 16 V) and dual-supply (±3 V to ±8 V) operation. Each channel conducts equally well in either direction when enabled and blocks voltages up to the supply rails when disabled.
Its internal design minimizes parasitic capacitance (CD(ON) = 15 pF, CS(OFF) = 5 pF) and charge injection (6.6 pC typ. at 12 V), ensuring high off-isolation (68.4 dB) and low crosstalk (114 dB) - critical for maintaining signal integrity in multi-channel ADC front-ends and programmable-gain amplifier topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 16 Ω typ. at 12 V - ensures minimal signal attenuation and gain error in precision sensor interfaces |
| Turn-on time | 18 ns typ. at 12 V - enables fast sampling in high-throughput data acquisition systems |
| Charge injection | 6.6 pC typ. - reduces hold-mode voltage step error in sample-and-hold circuits |
| Analog signal range | 0 to 12 V (single supply) or ±5 V (dual supply) - supports rail-to-rail input handling without clamping distortion |
| Leakage current | <10 pA typ. at 25 °C - preserves accuracy in high-impedance sensor and metering applications |
| Off isolation | 68.4 dB at 1 MHz - suppresses interference between active and inactive channels |
| Supply voltage range | 3 V to 16 V single or ±3 V to ±8 V dual - provides flexibility across portable, industrial, and medical power architectures |
Pinout & Package
Package: 16-lead TSSOP (JEDEC MS-012, body dimensions 5.00 × 4.40 × 1.20 mm). Pinout validated per Vishay S25-0564 Rev. B functional diagram and pin configuration table.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 (IN1–IN4) | Digital control inputs | Active-low logic for NC function: logic '0' closes switch, logic '1' opens switch |
| 5, 6, 11, 12 (S1–S4) | Switch source terminals | Input side of analog path; bidirectional conduction when enabled |
| 7, 8, 15, 16 (D1–D4) | Switch drain terminals | Output side of analog path; connects to Sx when switch is closed |
| 9 (GND) | Analog/digital ground reference | Common return for supplies and logic; must be low-impedance for noise control |
| 10 (V−) | Negative supply rail | Required for dual-supply operation; sets lower bound of analog signal range |
| 13 (V+) | Positive supply rail | Primary power for analog path and logic interface; defines upper analog voltage limit |
| 14 (NC) | No-connect terminal | Internally unused; must remain unconnected per datasheet guidance |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Higher on-resistance (35 Ω typ.), slower tON (60 ns typ.), SOIC-16 only | Less suitable for high-speed sampling; better for general-purpose relay replacement | Select when SOIC footprint is required and speed/resistance specs are relaxed |
| ADG1411YRUZ | Lower on-resistance (1.3 Ω typ.), higher supply voltage limit (+36 V), TSSOP-16 | Over-specified for low-voltage medical devices; higher cost and power consumption | Select only when ultra-low RDS(on) or extended voltage range justifies premium cost |
Compared with MAX4617ESE+ and ADG1411YRUZ, the DG441LEDQ-GE3 offers optimal balance of speed (18 ns), precision (6.6 pC charge injection), and low-voltage operation (3 V min) in a compact TSSOP-16 package - making it preferred for portable instrumentation where size, accuracy, and battery efficiency are co-constrained.

FAQ
What is the logic configuration of DG441LEDQ-GE3?
The DG441LEDQ-GE3 is a normally closed (NC) quad SPST analog switch: a logic low (≤0.8 V) on INx closes the corresponding Sx–Dx path, while a logic high (≥2.4 V) opens it. This fail-safe behavior maintains signal continuity during power loss or controller reset - a critical feature in DG441LEDQ-GE3-based patient monitoring and safety-critical sensor interfaces.
Does DG441LEDQ-GE3 support dual-supply operation?
Yes, DG441LEDQ-GE3 operates on dual supplies from ±3 V to ±8 V. At ±5 V, it delivers 18 Ω typical on-resistance and 42 ns typical turn-on time. The device handles analog signals from V− to V+, enabling true bipolar signal switching - essential for DG441LEDQ-GE3 use in precision instrumentation with AC-coupled sensor inputs.
What is the maximum analog signal voltage DG441LEDQ-GE3 can handle?
DG441LEDQ-GE3 supports analog signals from V− to V+ across its full operating range. With ±5 V dual supply, the signal range is –5 V to +5 V; with 12 V single supply, it is 0 V to 12 V. Exceeding these limits triggers internal clamp diodes - so DG441LEDQ-GE3 must be used within specified supply rails to avoid distortion or damage.
How does DG441LEDQ-GE3 minimize switching glitches in sample-and-hold circuits?
DG441LEDQ-GE3 achieves low switching glitch through <8 pC typical charge injection and matched on-resistance (0.1 Ω typ.). In sample-and-hold applications, this minimizes the voltage step injected onto the hold capacitor during switching - directly improving DG441LEDQ-GE3-based circuit accuracy and settling time, especially at high sampling rates.
Is DG441LEDQ-GE3 RoHS-compliant and lead-free?
Yes, DG441LEDQ-GE3 is RoHS-compliant and lead-free, as confirmed by Vishay's ordering information (suffix "-GE3") and material categorization documentation (www.vishay.com/doc?99912). The TSSOP-16 package uses matte tin lead finish, meeting JEDEC J-STD-020 moisture sensitivity level 1 - making DG441LEDQ-GE3 suitable for lead-free reflow assembly in medical and industrial products.
