Product details
Overview
DG441BDY-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 and medical instrumentation sample-and-hold stages.
For engineers reviewing the DG441BDY-E3 datasheet, DG441BDY-E3 pinout, DG441BDY-E3 application, or DG441BDY-E3 equivalent, key selection criteria include guaranteed low charge injection (–1 pC), rail-to-rail analog signal range (±15 V), TTL/CMOS-compatible control logic, and SOIC-16 packaging with validated thermal derating above 75 °C.
Technical Context
The DG441BDY-E3 implements four independent, bidirectional SPST switches using high-voltage silicon-gate CMOS technology with an epitaxial latchup prevention layer. Each channel conducts equally in both directions when ON and blocks signals beyond supply rails when OFF.
It supports dual-supply operation (V+ = +15 V, V– = –15 V) and single-supply mode (V+ = 12 V, V– = 0 V), with logic thresholds fixed at VINL ≤ 0.8 V and VINH ≥ 2.4 V. Charge injection is minimized at the drain terminal to reduce pedestal error in sample-and-hold circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RDS(on)) | 45 Ω typ. - ensures minimal signal attenuation and gain error in precision gain-setting resistor networks |
| Turn-On Time (tON) | 120 ns typ. - enables sub-microsecond channel switching for high-throughput data acquisition systems |
| Charge Injection (Q) | –1 pC typ. - limits voltage pedestal shift to <1 mV in 1 nF hold capacitors, critical for 12-bit+ accuracy |
| Analog Signal Range | ±15 V - supports full-range bipolar signal handling without external level-shifting circuitry |
| Off Isolation (OIRR) | –90 dB at 100 kHz - suppresses crosstalk between adjacent channels in multi-channel multiplexing |
| Supply Current (I+, I–) | ±1 µA max. - enables ultra-low-power standby operation in battery-backed instrumentation |
| Logic Compatibility | TTL/CMOS - allows direct interfacing with microcontrollers and FPGAs without level translators |
Pinout & Package
Package: 16-pin narrow-body SOIC (JEDEC MS-012), 3.80–4.00 mm width, 9.80–10.00 mm length, 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | IN1–IN4 | Digital control inputs - active-high logic enables corresponding switch; compatible with 3.3 V/5 V logic |
| 2, 6, 10, 14 | S1–S4 | Source terminals - bidirectional analog path input/output; tied to system ground reference in sample-and-hold |
| 3, 7, 11, 15 | D1–D4 | Drain terminals - bidirectional analog path input/output; drain-side charge injection minimized for low pedestal error |
| 4 | V– | Negative supply rail - must be connected to stable negative bias (e.g., –15 V) for bipolar operation |
| 8 | V+ | Positive supply rail - supplies internal switch driver; supports up to +15 V for full analog range |
| 12 | GND | Analog/digital common reference - separate from power supply return; requires low-impedance star grounding |
| 16 | NC | No connect - internally unconnected; must remain floating per datasheet requirement |
Key Features
| Feature | Design Value |
|---|---|
| Low on-resistance matching | ΔRDS(on) ≤ 4 Ω max. - maintains channel-to-channel gain consistency in programmable-gain amplifier topologies |
| High off-isolation | –90 dB at 100 kHz - isolates active and inactive signal paths in automatic test equipment multiplexers |
| Low off-capacitance | CS(off)/CD(off) = 4 pF - minimizes capacitive loading on high-impedance sensor nodes and op-amp feedback paths |
| Latchup immunity | Epitaxial silicon-gate process - prevents destructive latchup under transient overvoltage conditions per JEDEC JESD78 |
| Rail-to-rail analog switching | VANALOG = ±15 V - eliminates clipping in ±10 V industrial sensor interfaces and medical ECG front-ends |

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 RDS(on) (100 Ω typ.), lower supply voltage range (±5 V max), no QFN option | Lower bandwidth suitability; limited to single-supply 5 V systems | Prefer DG441BDY-E3 for ±15 V bipolar signal chains requiring <50 Ω on-resistance |
| ADG441BRZ | Similar RDS(on) (45 Ω), but higher charge injection (±2.5 pC), SOIC-16 pinout identical | Reduced sample-and-hold accuracy due to 2.5× higher pedestal error | Choose DG441BDY-E3 where <1 pC charge injection is mandatory for 12-bit+ precision hold circuits |
Compared with MAX4617ESE+ and ADG441BRZ, the DG441BDY-E3 delivers superior bipolar signal handling (±15 V), lowest verified charge injection (–1 pC), and tighter on-resistance matching - making it the preferred choice for medical-grade sample-and-hold and high-fidelity data acquisition where analog fidelity is non-negotiable.

FAQ
What is the maximum allowable analog signal voltage range for DG441BDY-E3?
The DG441BDY-E3 supports a full analog signal range of ±15 V when operated with dual supplies (V+ = +15 V, V– = –15 V). This rail-to-rail capability allows direct connection to ±10 V industrial sensors and medical transducers without external level-shifting circuitry. Exceeding these limits risks clamping by internal protection diodes and may violate absolute maximum ratings.
Does DG441BDY-E3 support single-supply operation?
Yes, the DG441BDY-E3 operates with single-supply configurations such as V+ = 12 V and V– = 0 V, delivering an analog signal range of 0 V to 12 V. In this mode, on-resistance increases to 90 Ω typ., and turn-on time remains within 300 ns. Logic inputs retain TTL/CMOS compatibility, simplifying integration with 3.3 V or 5 V microcontrollers.
How does the charge injection specification of DG441BDY-E3 impact sample-and-hold performance?
The DG441BDY-E3 specifies –1 pC typical charge injection at the drain terminal, directly limiting pedestal error in sample-and-hold circuits. With a 1 nF hold capacitor, this yields <1 mV step error - enabling 12-bit accuracy without trimming. This value is guaranteed by design and validated across temperature, making DG441BDY-E3 suitable for precision medical and test equipment where baseline stability is critical.
Is DG441BDY-E3 pin-compatible with the original DG441 series?
Yes, DG441BDY-E3 maintains identical pinout and electrical behavior with legacy DG441 variants (e.g., DG441DJ), including SOIC-16 footprint and logic polarity. It is a functional upgrade with improved on-resistance (45 Ω vs. 60 Ω), faster switching (120 ns vs. 150 ns), and reduced charge injection (–1 pC vs. –2.5 pC), allowing drop-in replacement in existing designs without layout changes.
What thermal derating applies to DG441BDY-E3 in SOIC package?
For the DG441BDY-E3 in narrow SOIC package, power dissipation must be derated by 12 mW/°C above 75 °C ambient. At 85 °C, the maximum allowed power drops from 900 mW (at 75 °C) to 780 mW. This derating ensures junction temperature remains within safe limits under sustained load, preserving long-term reliability in industrial environments.
