Product details

Overview

DG441LDQ-T1-E3 from Vishay Siliconix is a precision monolithic quad SPST low-voltage CMOS analog switch in 16-pin TSSOP package, featuring 17 Ω typical on-resistance, 20 ns turn-on time, and ±3 V to ±6 V dual 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 requiring low charge injection (5 pC) and high off-isolation (71 dB at 1 MHz).

For engineers reviewing the DG441LDQ-T1-E3 datasheet, DG441LDQ-T1-E3 pinout, DG441LDQ-T1-E3 application, or DG441LDQ-T1-E3 equivalent, key selection criteria include guaranteed R_DS(on) flatness over signal range, TTL/CMOS-compatible control logic, 2000 V ESD protection, and validated performance at 3 V, 5 V, and 12 V supply rails.

Technical Context

The DG441LDQ-T1-E3 implements four independent normally open analog switches with complementary control logic versus DG442L - logic "0" enables conduction, logic "1" disables. Its BiCMOS process enables simultaneous low on-resistance (20 Ω typ. at 12 V), fast switching (t_ON/t_OFF = 20 ns/12 ns), and minimal signal distortion across full analog voltage range (0–12 V single supply or ±5 V dual supply).

It features rail-to-rail analog signal handling, 0.25 nA max channel leakage at room temperature, and guaranteed crosstalk rejection of –95 dB at 1 MHz. Input thresholds are fixed at ≤0.8 V for logic low and ≥2.4 V for logic high, ensuring robust interfacing with standard digital controllers without level-shifting circuitry.

Key Specifications

Parameter	Value and Actual Design Meaning
On-resistance (R_DS(on))	20 Ω typical at 12 V supply - ensures minimal voltage drop and signal attenuation in precision analog paths
Turn-on time (t_ON)	20 ns typical - supports high-speed multiplexing in data acquisition and communication systems
Off-isolation (OIRR)	71 dB at 1 MHz - suppresses unwanted coupling between inactive channels in sensitive measurement circuits
Charge injection	5 pC typical - limits voltage glitch at sample-hold nodes and preserves DC accuracy
Analog signal range	0 to 12 V (single supply) or ±5 V (dual supply) - enables direct interface with sensors, DACs, and ADCs without external biasing
Supply voltage range	2.7 V to 12 V single or ±3 V to ±6 V dual - supports battery-powered and industrial rail-flexible designs
ESD protection	2000 V HBM - enhances robustness during PCB handling and system integration

Pinout & Package

Package: 16-pin TSSOP (JEDEC MS-012), 4.4 mm × 5.0 mm body, 0.65 mm pitch, exposed pad optional per Vishay Doc. 74417.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4 (IN1–IN4)	Digital control inputs	Active-low logic: logic "0" (≤0.8 V) closes corresponding switch; compatible with TTL/CMOS outputs
5, 6, 13, 14 (S1–S4)	Switch source terminals	Analog input nodes - connect to signal sources (e.g., sensor outputs, DACs)
7, 8, 11, 12 (D1–D4)	Switch drain terminals	Analog output nodes - route to ADC inputs, amplifiers, or signal processors
9 (GND)	Analog/digital ground reference	Common return for supplies and logic - must be low-impedance to minimize noise coupling
10 (V−)	Negative supply rail	Required for dual-supply operation (±3 V to ±6 V); tied to GND for single-supply use
15, 16 (V+)	Positive supply rail	Primary power input - accepts 2.7–12 V; both pins must be connected for low-impedance path
NC (Pin 10 not used)	No-connect terminal	Not internally bonded - left unconnected per datasheet; no routing or grounding required

Key Features

Feature	Design Value
Rail-to-rail analog switching	Supports full 0–12 V or ±5 V signal swing without clipping - eliminates need for external level-shifting in mixed-signal systems
Break-before-make action	Guarantees no momentary short between channels during switching - prevents signal corruption in multiplexed sensor arrays
Low on-resistance match (ΔR_DS(on))	0.1 Ω typical matching between channels - critical for precision gain-setting and weighted resistor networks
Ultra-low leakage current	±1 nA max off-state leakage at room temperature - preserves integrity of high-impedance nodes in sample-and-hold and medical front-ends
Halogen-free & RoHS-compliant	Meets IEC 61249-2-21 and Directive 2002/95/EC - satisfies environmental compliance for global industrial and telecom deployments

Equivalent & Alternatives

The following parts are listed as comparable options for similar analog switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MAX4618ESE+	Higher R_DS(on) (45 Ω typ. at 5 V), slower t_ON (40 ns), no dual-supply support	Optimized for 3–5.5 V single-supply only; lacks ±5 V capability	Choose when cost sensitivity outweighs speed and rail flexibility
ADG1419BRUZ	Lower R_DS(on) (1.3 Ω typ.), higher supply voltage (up to ±15 V), larger SOIC-16 package	Targets high-precision industrial control; requires more board area and higher BOM cost	Choose when sub-2 Ω on-resistance and extended voltage range justify footprint and cost premium

Compared with MAX4618ESE+ and ADG1419BRUZ, DG441LDQ-T1-E3 uniquely balances 20 ns speed, 20 Ω on-resistance, dual-supply operation, and TSSOP-16 compactness - making it optimal for space-constrained, multi-rail portable test equipment where timing, leakage, and layout density are co-critical.

FAQ

What supply voltage ranges does the DG441LDQ-T1-E3 support?

The DG441LDQ-T1-E3 operates from 2.7 V to 12 V on a single supply or ±3 V to ±6 V on dual supplies. At 12 V, R_DS(on) is 20 Ω typical; at ±5 V, it is 20 Ω typical; at 3 V, it rises to 65 Ω typical. All specifications in the Vishay datasheet Document Number 71399 are validated across these rails, with temperature ranges defined by the D suffix (–40 °C to +85 °C).

Is the DG441LDQ-T1-E3 pin-compatible with the industry-standard DG441?

Yes, the DG441LDQ-T1-E3 is explicitly described in the Vishay datasheet as "low voltage pin-for-pin compatible companion devices to the industry standard DG441L, DG442L with improved performance." Pinout matches standard 16-pin SOIC and TSSOP layouts, including identical IN/S/D/V+/V−/GND assignments and NC placement.

What is the maximum analog signal voltage the DG441LDQ-T1-E3 can switch?

The DG441LDQ-T1-E3 supports full rail-to-rail analog signals: 0 V to V+ (up to 12 V) in single-supply mode, or –V− to +V+ (±5 V) in dual-supply mode. Absolute maximum ratings allow signals up to V+ + 0.3 V or V− – 0.3 V, clamped by internal diodes - but sustained operation beyond rails risks exceeding 30 mA forward diode current limits.

Does the DG441LDQ-T1-E3 require external pull-up or pull-down resistors on its control inputs?

No. The DG441LDQ-T1-E3 has TTL/CMOS-compatible inputs with guaranteed logic thresholds: ≤0.8 V for logic low and ≥2.4 V for logic high across –40 °C to +85 °C. Input leakage is ±1.5 µA max, so direct connection to FPGA GPIO, MCU pins, or logic gates is fully supported without external biasing.

How does the DG441LDQ-T1-E3 achieve low charge injection in sample-and-hold circuits?

The DG441LDQ-T1-E3 achieves 5 pC typical charge injection through matched transistor geometry and optimized gate drive in its BiCMOS process. As confirmed in Figure 3 of Vishay Doc. 71399, this value is measured with V_g = 0 V, R_g = 0 Ω, and C_L = 10 nF - directly enabling low-glitch sampling in precision hold capacitors without additional correction circuitry.
