Product details
Overview
DG441LDQ-E3 from Vishay Siliconix is a precision monolithic quad SPST low-voltage CMOS analog switch in 16-pin TSSOP package, featuring 17 Ω on-resistance, 20 ns turn-on time, and ±3 V to ±6 V dual-supply or 2.7 V to 12 V single-supply operation. It delivers break-before-make switching for audio/video signal routing and precision data acquisition systems.
For engineers reviewing the DG441LDQ-E3 datasheet, DG441LDQ-E3 pinout, DG441LDQ-E3 application, or DG441LDQ-E3 equivalent, key selection criteria include guaranteed RDS(on) flatness over signal range, sub-1 pC charge injection at 3 V, -50 dB off-isolation at 50 MHz, TTL/CMOS logic compatibility, and 2000 V HBM ESD rating - all validated across -40 °C to +85 °C.
Technical Context
The DG441LDQ-E3 implements four independent normally-open analog switches using BiCMOS process technology, enabling simultaneous operation on single (2.7–12 V) or dual (±3–±6 V) supplies. Its control logic is active-low: INx = 0 V enables channel conduction; INx = 2.4 V disables it - opposite to DG442L's polarity.
Each channel exhibits flat on-resistance (<5 Ω variation over full analog range), minimal crosstalk (95 dB at 1 MHz), and low leakage (±1 nA max at room temperature). The device supports rail-to-rail analog signal switching up to 12 V or ±5 V, with guaranteed performance down to 2.7 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 17 Ω typical at 12 V single supply - ensures minimal signal attenuation and thermal drift in precision gain-setting networks |
| Turn-on time | 20 ns typical - enables high-speed multiplexing in >10 MSPS data acquisition without timing skew |
| Analog signal range | 0 to 12 V (single supply) or ±5 V (dual supply) - supports full-rail audio, sensor, and DAC output switching |
| Charge injection | 5 pC typical - limits voltage glitch in sample-and-hold circuits to <1 mV with 10 nF hold capacitor |
| Off-isolation | -50 dB at 50 MHz - suppresses interference between adjacent channels in RF-adjacent video routing |
| ESD rating | 2000 V HBM - allows safe handling during automated PCB assembly without special grounding protocols |
| Supply range | 2.7–12 V single or ±3–±6 V dual - enables direct interface with Li-ion battery, 3.3 V MCU, and legacy 5/12 V systems |
Pinout & Package
Package: 16-pin TSSOP (JEDEC MS-012), 4.4 mm × 5.0 mm body, 0.65 mm pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 15, 16 | IN1–IN4 | Active-low digital control inputs - drive with 0.8 V / 2.4 V logic thresholds; no pull-up required |
| 3, 4, 13, 14 | S1–S4 | Switch source terminals - connect to analog signal sources; bidirectional conduction when enabled |
| 5, 6, 11, 12 | D1–D4 | Switch drain terminals - route switched signals to destinations; matched impedance to S pins |
| 7 | V− | Negative supply rail - required for dual-supply operation; tied to GND in single-supply mode |
| 8 | GND | Analog/digital ground reference - must be low-impedance star point for leakage-sensitive applications |
| 9 | NC | No-connect terminal - left unconnected per datasheet; no internal bond wire or circuitry |
| 10 | V+ | Positive supply rail - powers analog switch core and level-shift circuitry; decoupling mandatory |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 5 ns minimum dead time prevents momentary short-circuit during channel transitions |
| RDS(on) matching | ≤0.5 Ω max mismatch between channels - enables precision resistor-programmable gain amplifier topologies |
| Low leakage current | ±1 nA max off-state leakage - preserves accuracy in high-impedance sensor front-ends and integrator circuits |
| Flat RDS(on) vs. voltage | ≤5 Ω variation over full analog range - eliminates gain nonlinearity in DC-coupled signal paths |
| TTL/CMOS compatibility | 0.8 V low / 2.4 V high input thresholds - interfaces directly with 3.3 V and 5 V microcontrollers without level shifters |
Applications
| Precision Data Acquisition | Audio Signal Routing |
|---|---|
Use Scenario: Multiplexing multiple sensor outputs into a single ADC channel with <0.01% gain error. IC Role / Device Role / Timing Role: Quad SPST switch selects one of four transducer signals while maintaining rail-to-rail linearity and sub-1 LSB settling. Use Value: 17 Ω RDS(on) and ≤0.5 Ω matching eliminate channel-to-channel gain variance; 5 pC charge injection prevents hold-step errors. |

IC Role / Device Role / Timing Role: Low-distortion analog switch handles 2 VPP signals with <−100 dB THD+N at 1 kHz. Use Value: −50 dB off-isolation at 50 MHz blocks crosstalk between left/right channels; 20 ns tON enables mute timing under 100 µs. |
| Battery-Powered Instrumentation | Communication System Front-End |
Use Scenario: Enabling/disabling power to analog subsystems (e.g., op-amp bias networks) in handheld test gear. IC Role / Device Role / Timing Role: Low-leakage SPST switch acts as precision load disconnect with <1 µA quiescent current. Use Value: ±1 nA off-leakage extends battery life in sleep mode; 2.7 V min supply supports single-cell Li-ion operation. |
Use Scenario: Selecting between DSLAM line drivers and diagnostic test points in broadband access equipment. IC Role / Device Role / Timing Role: High-speed analog switch routes 1–30 MHz SDSL signals with minimal insertion loss. Use Value: −3 dB bandwidth of 280 MHz ensures flat response across ADSL2+ spectrum; 95 dB crosstalk isolates upstream/downstream paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Single-supply only (2.7–12 V); 35 Ω RDS(on); 30 ns tON; no dual-supply support | Limited to single-rail systems; higher on-resistance increases gain error in precision resistor networks | Choose when dual-supply operation is unnecessary and cost sensitivity outweighs RDS(on) and speed requirements |
| ADG1412BRUZ | 4-channel, SPST, but with 1.3 Ω RDS(on), 17 ns tON, and ±15 V capability - requires ±15 V supplies | Supports higher voltage rails but incompatible with low-voltage battery systems due to supply constraints | Choose for industrial systems requiring <2 Ω on-resistance and ±15 V signal handling, not for 3.3 V portable designs |
Compared with MAX4617ESE+ and ADG1412BRUZ, DG441LDQ-E3 uniquely balances low-voltage operation (2.7 V), dual-supply flexibility (±3 V), 17 Ω RDS(on), and 20 ns speed - making it optimal for mixed-signal portable instrumentation where supply headroom and precision coexist.

FAQ
What supply configurations does the DG441LDQ-E3 support?
The DG441LDQ-E3 operates on either a single supply (2.7 V to 12 V, with V− tied to GND) or dual supplies (±3 V to ±6 V). At 12 V single supply, RDS(on) is 17 Ω typical; at ±5 V dual supply, it is 20 Ω typical. The DG441LDQ-E3 requires no external level shifters for TTL/CMOS logic interfacing in either configuration.
How does the DG441LDQ-E3 handle analog signals near the supply rails?
The DG441LDQ-E3 supports rail-to-rail analog signal switching: 0 V to 12 V with single 12 V supply, or ±5 V with dual ±5 V supplies. Its BiCMOS architecture ensures flat RDS(on) (≤5 Ω variation) across the full analog range, minimizing distortion and gain error in DC-coupled paths - critical for precision applications like programmable-gain amplifiers.
Is the DG441LDQ-E3 pin-compatible with industry-standard analog switches?
Yes, the DG441LDQ-E3 is pin-for-pin compatible with the industry-standard DG441 and DG442 families, including legacy variants. Its 16-pin TSSOP footprint matches DG441LDQ-T1-E3 and DG441LDY-T1-E3, enabling drop-in replacement in existing layouts without PCB revision - confirmed by Vishay's ordering information table and functional block diagram.
What is the maximum signal frequency supported by the DG441LDQ-E3?
The DG441LDQ-E3 maintains −3 dB insertion loss up to 280 MHz under 12 V single-supply conditions (RL = 50 Ω). Its −50 dB off-isolation at 50 MHz and 95 dB channel-to-channel crosstalk ensure clean signal separation in multi-channel video and broadband communication routing - verified in the "Insertion Loss, Off Isolation and Crosstalk vs. Frequency" plot.
Does the DG441LDQ-E3 require external protection against overvoltage on analog pins?
Yes - analog pins (Sx, Dx) exceeding V+ or V− are clamped by internal diodes, but forward diode current must be limited to rated maximums (30 mA continuous, 100 mA pulsed). External series resistors or TVS diodes are recommended for transient overvoltage events beyond absolute maximum ratings (e.g., >13 V between V+ and V−), as stated in Note "a" of the Absolute Maximum Ratings table.
