Product details
Overview
DG411DY-T1 from Vishay Siliconix is a precision monolithic quad SPST CMOS analog switch with break-before-make action, 25 Ω typical on-resistance at ±15 V supplies, 110 ns turn-on time, and ±15 V analog signal range. It operates from dual ±15 V or single 12 V supplies and is used in precision data acquisition systems requiring low signal distortion and high channel isolation.
For engineers reviewing the DG411DY-T1 datasheet, DG411DY-T1 pinout, DG411DY-T1 application, or DG411DY-T1 equivalent, key selection criteria include guaranteed rDS(on) ≤ 45 Ω over temperature, 68 dB off-isolation at 1 MHz, TTL/CMOS-compatible control inputs, and SOIC-16 packaging for surface-mount industrial PCBs.
Technical Context
The DG411DY-T1 implements four independent bidirectional SPST switches fabricated using Vishay's high-voltage silicon gate process with epitaxial latchup protection. Each switch conducts equally in both directions when on and blocks signals up to the supply rails when off.
It uses standard logic-level control (0.8 V low / 2.4 V high) referenced to VL, supports single-supply operation (V– = GND, V+ = VL), and features break-before-make timing only in DG413 variants-DG411DY-T1 has non-overlapping switching with no intentional delay between channels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V (full rail-to-rail conduction with ±15 V supplies; enables direct interfacing with op-amp outputs and sensor front-ends) |
| rDS(on) Typ / Max | 25 Ω / 45 Ω (ensures minimal voltage drop and gain error in precision signal paths at room temperature) |
| tON / tOFF | 110 ns / 100 ns (supports multiplexing of signals up to ~3 MHz without significant settling degradation) |
| OIRR | 68 dB (guarantees >2000:1 attenuation of off-channel interference in multi-channel measurement systems) |
| Charge Injection | 5 pC (limits output step error to <1 LSB in 16-bit 10 kΩ-input ADC sample-and-hold circuits) |
| Supply Voltage Range | ±15 V dual or 12 V single (enables compatibility with legacy ±15 V instrumentation and modern 12 V embedded systems) |
| Logic Compatibility | TTL and CMOS (accepts 0.8 V low / 2.4 V high thresholds; interfaces directly with microcontrollers and FPGAs without level-shifting) |
Pinout & Package
Package: 16-pin narrow SOIC (width 3.9 mm), RoHS-compliant, rated for –40 °C to +85 °C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control inputs | Active-high logic; each controls corresponding Sx/Dx switch pair (DG411 logic: INx = 1 → open, INx = 0 → closed) |
| S1–S4 | Switch source terminals | Bidirectional analog I/O; connect to signal sources (e.g., sensor outputs, DACs) |
| D1–D4 | Switch drain terminals | Bidirectional analog I/O; connect to loads (e.g., ADC inputs, amplifier inputs) |
| V+ | Positive analog supply | Accepts +5 V to +44 V; sets upper analog rail and powers internal switch circuitry |
| V− | Negative analog supply | Accepts –5 V to –44 V; sets lower analog rail; must be ≤ –2 V for full spec compliance |
| GND | Analog ground reference | Return path for V− and substrate bias; separate from digital ground in mixed-signal layouts |
| VL | Logic supply reference | Defines logic threshold; tied to V+ in single-supply mode; typically 5 V for TTL compatibility |
Key Features
| Feature | Design Value |
|---|---|
| Precision analog switching | Guaranteed rDS(on) ≤ 45 Ω and flatness < 2 Ω across ±10 V signal range ensures < 0.02% gain error in calibrated measurement paths |
| Ultra-low leakage | Channel off-leakage ≤ ±5 nA and on-leakage ≤ ±10 nA preserve accuracy in high-impedance (>1 MΩ) sensor interfaces |
| High off-isolation | 68 dB OIRR at 1 MHz minimizes crosstalk between adjacent channels in 16-channel data loggers |
| Break-before-make (non-intentional) | No overlap in switch timing (tD not specified for DG411); prevents momentary shorting in multiplexer configurations |
| Single-supply flexibility | Operates with V– = GND and V+ = VL = 12 V, simplifying power design in battery-powered portable instruments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Lower rDS(on) (15 Ω typ), but only ±10 V signal range and no 44 V abs-max rating | Better for low-voltage precision systems; unsuitable for ±15 V industrial sensors | Select when signal swing < ±10 V and on-resistance < 20 Ω is critical |
| ADG411BRZ | Same pinout, 35 Ω rDS(on), wider temp range (–40°C to +125°C), higher 125 ns tON | Drop-in replacement for extended temperature deployments; slightly slower switching | Choose for automotive or harsh-environment use where Vishay DG411DY-T1's 85°C limit is insufficient |
Compared with MAX4617ESE+ and ADG411BRZ, DG411DY-T1 uniquely balances ±15 V signal integrity, 44 V robustness, and 110 ns speed in a narrow SOIC package-making it optimal for industrial DAQ where rail-to-rail fidelity and supply margin outweigh marginal on-resistance gains.

FAQ
What is the maximum supply voltage rating for DG411DY-T1?
The DG411DY-T1 supports a maximum analog supply voltage of ±44 V across V+ and V− pins. This 44 V rating applies to the differential voltage between V+ and V−, not individual rail limits. Operation at ±15 V is fully characterized and recommended for precision performance, while the 44 V absolute maximum ensures robustness against transient overvoltage events in industrial environments. The DG411DY-T1 must not be operated with V+ or V− exceeding their respective absolute maximum ratings relative to GND.
Does DG411DY-T1 support single-supply operation?
Yes, DG411DY-T1 supports single-supply operation with V− tied to GND and V+ connected to the positive supply (5 V to 44 V). In this configuration, VL must be tied to V+, and logic inputs remain compatible with TTL/CMOS levels. The device maintains its ±12 V analog signal range under 12 V single-supply conditions, as confirmed in the datasheet's unipolar test conditions. This mode is widely used in portable instrumentation to eliminate negative supply generation.
What is the guaranteed on-resistance specification for DG411DY-T1 over temperature?
The DG411DY-T1 guarantees rDS(on) ≤ 45 Ω over its full operating temperature range of –40 °C to +85 °C, measured at V+ = ±13.5 V, V− = ∓13.5 V, IS = –10 mA, and VD = 8.5 V. This maximum value ensures predictable voltage drop and gain error in precision signal paths across industrial ambient conditions. Typical rDS(on) is 25 Ω at room temperature, and the parameter exhibits monotonic increase with temperature, remaining within specification up to +85 °C.
How does DG411DY-T1 handle charge injection in sample-and-hold circuits?
DG411DY-T1 specifies 5 pC typical charge injection at room temperature, measured with Vg = 0 V, Rg = 0 Ω, and CL = 10 nF. In a 16-bit ADC system with 10 kΩ input impedance, this results in a maximum output step error of ~0.5 mV-well below 1 LSB for a ±10 V full-scale range. The low and tightly bounded charge injection enables accurate sampling without requiring complex correlated double sampling or external clamping networks in medium-speed DAQ designs.
Is DG411DY-T1 pin-compatible with other members of the DG411/412/413 family?
Yes, DG411DY-T1 shares identical pinout and package with DG412DY and DG413DY in the 16-pin narrow SOIC variant. However, logic polarity differs: DG411DY-T1 turns switches ON with logic low (INx = 0), whereas DG412DY uses inverted control (ON with INx = 1). DG413DY integrates two normally-open and two normally-closed switches per package. Thus, while mechanical and layout compatible, firmware or logic interface changes are required when substituting between DG411DY-T1, DG412DY, or DG413DY.
