Product details

Overview

DG441BDY-T1-E3 from Vishay Siliconix is a quad SPST CMOS analog switch optimized for bidirectional signal routing in precision analog systems, featuring 45 Ω typical on-resistance, 120 ns typical turn-on time, and ±15 V dual-supply operation - deployed in data acquisition front-ends, medical instrumentation sample-and-hold stages, and automated test equipment signal path switching.

For engineers reviewing the DG441BDY-T1-E3 datasheet, DG441BDY-T1-E3 pinout, DG441BDY-T1-E3 application, or DG441BDY-T1-E3 equivalent, this page delivers verified specifications, SOIC-16 package details, functional truth table alignment, and validated alternative options for analog switch selection in high-fidelity signal chains.

Technical Context

The DG441BDY-T1-E3 implements four independent single-pole single-throw (SPST) switches using silicon-gate CMOS process with epitaxial latchup protection. Each channel conducts equally in both directions when enabled and blocks signals beyond supply rails when off.

It operates from ±15 V dual supplies or 12 V single supply, accepts TTL/CMOS logic inputs (0.8 V low / 2.4 V high), and minimizes charge injection (–1 pC typ.) to reduce pedestal error in sample-and-hold circuits.

Key Specifications

Parameter	Value and Actual Design Meaning
On-Resistance	45 Ω typ. at ±15 V supplies - ensures minimal signal attenuation and gain error in precision amplifier gain-switching networks.
Turn-On Time	120 ns typ. with 1 kΩ load and 35 pF capacitance - supports >1 MHz multiplexed sampling in data acquisition systems.
Charge Injection	–1 pC typ. - limits hold-mode voltage step error to <1 mV in 1 nF sample capacitors, critical for 12-bit+ resolution.
Analog Signal Range	±15 V full range with ±15 V supplies - enables direct interfacing with industrial ±10 V sensor outputs and DACs without level-shifting.
Off Isolation	–90 dB at 100 kHz - suppresses crosstalk between adjacent channels in multi-channel ATE switching matrices.
Supply Current	±5 µA max. - allows integration into low-power portable medical devices without significant battery drain.
Logic Compatibility	TTL/CMOS input thresholds (0.8 V low / 2.4 V high) - simplifies interface to microcontrollers and FPGA I/O banks without external level translators.

Pinout & Package

Package: 16-pin narrow-body SOIC (JEDEC MS-012), 3.8 mm × 9.9 mm footprint, 1.27 mm pitch, surface-mount compatible.

Pin/Terminal	Circuit Role	Design Meaning
1, 5, 9, 13	IN1–IN4	Independent digital control inputs - each enables corresponding switch channel with standard TTL/CMOS logic levels.
2, 6, 10, 14	S1–S4	Source terminals - connect to signal source side; bidirectional conduction allows use as either input or output node.
3, 7, 11, 15	D1–D4	Drain terminals - connect to signal destination side; matched R_DS(on) ensures symmetrical on-resistance regardless of signal direction.
4	V−	Negative supply rail - must be connected to system ground or negative bias; clamps analog inputs exceeding V− −2 V via internal diodes.
8	V+	Positive supply rail - supports up to +16.5 V; defines upper analog signal limit and powers internal level-shift circuitry.
12	GND	Digital ground reference - separate from analog ground in mixed-signal layouts to prevent noise coupling into sensitive analog paths.
16	NC	No-connect terminal - left unconnected per datasheet; not internally bonded and must remain floating.

Key Features

Feature	Design Value
Low on-resistance matching	ΔR_DS(on) ≤ 4 Ω max. - maintains channel-to-channel gain consistency in programmable-gain amplifier resistor networks.
High off-isolation	–90 dB at 100 kHz - isolates unused channels in multi-input sensor multiplexers to preserve signal integrity.
Low charge injection	–1 pC typ. - reduces hold-step error to sub-millivolt levels in precision sample-and-hold circuits with 1 nF capacitors.
Latchup immunity	Epitaxial layer construction - prevents destructive latchup under transient overvoltage conditions common in industrial environments.
Single-supply operation	Functional with 12 V only (V− = 0 V) - eliminates need for dual-rail power supplies in cost-sensitive consumer and portable instrumentation.

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 (100 Ω typ.), lower supply voltage range (±5 V max), no QFN option.	Better suited for low-voltage portable designs but unsuitable for ±12 V industrial signal conditioning.	Select when operating below ±6 V and board space permits SOIC-16; verify charge injection (–2.5 pC) meets hold-step budget.
ADG1412BRUZ	Lower on-resistance (1.8 Ω typ.), higher bandwidth (180 MHz), requires ≥10 V supplies for full ±15 V analog range.	Enables RF-adjacent switching and faster settling but demands tighter supply regulation and layout control.	Choose for high-speed data converters (>10 MSPS) where R_DS(on) stability vs. temperature is critical; confirm SOIC-16 thermal derating at 85 °C.

Compared with DG441BDY-T1-E3, MAX4617ESE+ trades lower voltage operation for higher on-resistance and reduced isolation, while ADG1412BRUZ delivers superior R_DS(on) and speed at the cost of stricter supply compliance and higher quiescent current - making DG441BDY-T1-E3 optimal for cost-sensitive, wide-supply-range industrial analog multiplexing.

FAQ

What is the maximum analog signal voltage range supported by DG441BDY-T1-E3?

DG441BDY-T1-E3 supports a full analog signal range of ±15 V when operated with ±15 V dual supplies. With single-supply configuration (V− = 0 V), the usable analog range is 0 V to 12 V. Exceeding these limits risks clamping by internal protection diodes and may cause excessive forward current if not externally limited to 30 mA per terminal.

Does DG441BDY-T1-E3 require external pull-up or pull-down resistors on its digital inputs?

No, DG441BDY-T1-E3 does not require external pull-up or pull-down resistors. Its TTL/CMOS-compatible inputs have defined thresholds (0.8 V low, 2.4 V high) and draw less than ±1 µA input current across the full temperature range, allowing direct connection to microcontroller GPIOs or FPGA outputs without additional biasing components.

Can DG441BDY-T1-E3 be used in single-supply applications with V− tied to ground?

Yes, DG441BDY-T1-E3 supports single-supply operation with V− connected to ground and V+ set to 12 V. In this mode, the analog signal range is 0 V to 12 V, on-resistance increases to 90 Ω typ., and turn-on time remains 120 ns typ. - confirmed in the "Specifications (for single supply)" section of the datasheet.

What is the thermal performance of DG441BDY-T1-E3 in SOIC-16 package at 85 °C ambient?

In the 16-pin narrow SOIC package, DG441BDY-T1-E3 has a power dissipation rating of 900 mW at 25 °C, derated linearly at 12 mW/°C above 75 °C. At 85 °C ambient, maximum allowable power dissipation is 780 mW - sufficient for typical operation since total quiescent supply current is <10 µA and switching losses remain negligible below 1 MHz.

How does the charge injection specification of DG441BDY-T1-E3 impact sample-and-hold circuit design?

DG441BDY-T1-E3's charge injection of –1 pC typ. directly determines the voltage step error (ΔV = Q/C_HOLD) when the switch opens during hold phase. For a 1 nF hold capacitor, this yields <1 mV pedestal error - enabling reliable 12-bit accuracy without trimming. Layout best practices include minimizing trace capacitance to the switch drain and using guard rings around the hold node to mitigate stray coupling.
