Product details
Overview
DG441DJ-E3 from Vishay Siliconix is a quad SPST analog switch with normally closed (NC) configuration, designed for high-speed, low-error switching of analog and audio signals in dual- or single-supply systems. It delivers 50 Ω typical on-resistance, 150 ns typical turn-on time, ±15 V dual-supply operation, and -1 pC charge injection - enabling precision sample-and-hold and data acquisition circuits.
For engineers reviewing the DG441DJ-E3 datasheet, DG441DJ-E3 pinout, DG441DJ-E3 application, or DG441DJ-E3 equivalent, key selection criteria include its NC logic behavior, low leakage (<0.5 nA off-state), TTL/CMOS-compatible control inputs, 16-pin plastic DIP package, and compatibility with legacy DG201A/DG202 socket upgrades.
Technical Context
The DG441DJ-E3 implements four independent, bidirectional SPST switches fabricated using Vishay's high-voltage silicon-gate process, featuring epitaxial latchup protection. Each channel conducts equally in both directions when on and blocks signals up to supply rails when off.
Its control logic is active-low for ON state (logic "0" ≤ 0.8 V enables conduction), with guaranteed switching across -40 °C to +85 °C. Charge injection is minimized at the drain terminal to reduce pedestal error in sampling applications, and internal clamping diodes protect against signal overvoltage beyond V+ or V−.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST, normally closed (NC) - all four channels conduct when control input is logic low |
| On-Resistance | 50 Ω typ. at ±15 V supplies - ensures minimal signal attenuation and gain error in precision amplifiers |
| Turn-On Time | 150 ns typ. (RL = 1 kΩ, CL = 35 pF) - supports >1 MHz signal switching in data acquisition systems |
| Charge Injection | -1 pC typ. - limits voltage step error in sample-and-hold circuits to <1 mV with 1 nF hold capacitor |
| Off-Leakage Current | ±0.5 nA max. at full temperature range - preserves accuracy in high-impedance sensor interfaces |
| Supply Range | ±5 V to ±22 V dual supply or +5 V to +36 V single supply - enables flexible rail design in industrial and medical equipment |
| Logic Compatibility | TTL/CMOS-compatible inputs (VIH ≥ 2.4 V, VIL ≤ 0.8 V) - simplifies interface with microcontrollers and FPGAs without level-shifting |
Pinout & Package
Package: 16-pin plastic DIP (JEDEC MS-012), 0.300" wide body, lead pitch 0.100", RoHS-compliant (E3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | IN1–IN4 | Active-low digital control inputs - logic "0" closes corresponding switch |
| 2, 4, 11, 15 | S1–S4 | Source terminals - bidirectional analog signal entry points for each NC switch |
| 3, 6, 12, 16 | D1–D4 | Drain terminals - bidirectional analog signal outputs; charge injection minimized here |
| 7 | V− | Negative supply rail - must be connected for dual-supply operation or grounded for single-supply use |
| 8 | GND | Analog/digital ground reference - shared return for supplies and logic |
| 10, 14 | V+ | Positive supply rail - powers analog core and logic interface; supports up to +36 V |
| 10, 14 | NC | No-connect pins - internally unused; must remain unconnected per datasheet |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional analog conduction | Enables signal routing in either direction without polarity constraints - ideal for multiplexing sensor inputs or audio paths |
| Low on-resistance match (≤5 Ω max) | Ensures consistent gain and channel-to-channel tracking in programmable-gain amplifier designs |
| Clamped I/O with diode protection | Prevents damage from signals exceeding V+ or V− by limiting forward current - eliminates need for external clamps in ruggedized systems |
| Single-supply capability (+5 V to +36 V) | Reduces system BOM count by eliminating negative rail generation in battery-powered or portable instrumentation |
| Epitaxial latchup immunity | Guarantees robust operation under transient overvoltage or ESD stress - critical for medical and test equipment reliability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617CPD+ | Quad SPST NO, 60 Ω RDS(on), 100 ns ton, requires external VEE for bipolar operation | Not pin-compatible; NO logic requires inverted control signals vs. DG441DJ-E3's NC behavior | Select when faster switching and lower on-resistance tolerance are prioritized over direct DG201A socket replacement |
| ADG441BNZ | Quad SPST NC, 45 Ω RDS(on), 120 ns ton, wider temp range (-40°C to +125°C), SOIC-16 only | Same NC function and pinout but different package - requires PCB redesign for DIP-16 footprint | Choose for extended temperature operation and slightly better speed/resistance, accepting SOIC layout change |
Compared with MAX4617CPD+ and ADG441BNZ, the DG441DJ-E3 offers verified DG201A socket compatibility, proven 16-pin DIP mechanical fit, and optimized charge injection for sample-and-hold - making it the preferred choice for legacy system upgrades and medical-grade precision analog routing where NC logic and DIP packaging are mandatory.

FAQ
What is the logic behavior of DG441DJ-E3?
The DG441DJ-E3 features normally closed (NC) SPST switches: each channel conducts when its INx pin is logic low (≤ 0.8 V) and opens when logic high (≥ 2.4 V). This active-low behavior matches legacy DG201A sockets and simplifies control in systems where default conduction is required during power-up or fault conditions. The DG441DJ-E3 does not require pull-up resistors for fail-safe operation.
Can DG441DJ-E3 operate from a single supply?
Yes, DG441DJ-E3 supports single-supply operation from +5 V to +36 V, with V− tied to GND. In this mode, analog signal range is 0 V to V+, and on-resistance increases to 100 Ω typ. (vs. 50 Ω typ. in ±15 V mode). The DG441DJ-E3 maintains TTL/CMOS compatibility and full functionality - making it suitable for battery-powered data loggers and portable medical devices.
What is the maximum signal voltage DG441DJ-E3 can switch?
The DG441DJ-E3 can switch analog signals from V− to V+ - i.e., ±15 V in dual-supply mode or 0 V to +12 V in single-supply mode. Absolute maximum ratings allow V+ to V− differential up to 44 V, but sustained signal excursion beyond supply rails is clamped by internal diodes. For reliable operation, keep signals within V− and V+ rails; the DG441DJ-E3 is not rated for overvoltage switching beyond these limits.
How does DG441DJ-E3 minimize errors in sample-and-hold circuits?
The DG441DJ-E3 minimizes sample-and-hold errors via ultra-low charge injection (-1 pC typ.) and low on-resistance (50 Ω typ.), which together limit pedestal voltage step and settling time. Its drain-terminal-optimized construction reduces injected charge directly into the hold capacitor, and the NC configuration allows seamless integration into open-loop S/H topologies like those shown in Vishay Application Note 826 - all confirmed in DG441DJ-E3 characterization data.
Is DG441DJ-E3 pin-compatible with DG201A?
Yes, DG441DJ-E3 is a direct drop-in upgrade for DG201A in 16-pin DIP sockets: identical pinout, NC logic, and mechanical footprint. It improves upon DG201A with 50 Ω vs. 90 Ω on-resistance, 150 ns vs. 350 ns turn-on time, and -1 pC vs. -5 pC charge injection - while maintaining backward compatibility. No PCB changes are required when replacing DG201A with DG441DJ-E3.
