Product details
Overview
DG441EEE from Intersil is a monolithic quad SPST CMOS analog switch with TTL/CMOS-compatible digital inputs, 85Ω max ON resistance, 250ns max tON, and ±20V analog signal range. It operates from single (5–34V) or split (±5V to ±22V) supplies and is used in precision sample-and-hold circuits, audio routing, and data acquisition systems.
For engineers reviewing the DG441EEE datasheet, DG441EEE pinout, DG441EEE application, or DG441EEE equivalent, this page delivers verified specifications, package mapping, functional truth table, real-world use cases, and two validated alternative parts for design-in flexibility under industrial temperature conditions.
Technical Context
The DG441EEE implements four independent bilateral analog switches using a high-voltage silicon-gate CMOS process, enabling 44V max V+–V− differential operation and latch-up immunity via epitaxial isolation. Its logic control is active-high (IN = HIGH → switch OFF), distinguishing it from the complementary DG442.
Each channel features matched source/drain terminals, low charge injection (±1pC typ), and flat ON-resistance variation across ±5V analog input swing. The device supports bidirectional AC/DC signals and maintains sub-100nA leakage at +85°C with dual ±15V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON Resistance (max) | 85Ω at +25°C, ±15V supplies - ensures minimal signal attenuation in precision gain-setting and sensor multiplexing paths |
| Turn-On Time (max) | 250ns with RL=1kΩ, CL=35pF - enables reliable switching in 1MHz data acquisition sampling |
| Analog Signal Range | ±20V max - supports full-rail operation with ±15V op-amps and industrial sensor interfaces |
| Supply Voltage Range | +5V to +34V single or ±5V to ±22V split - accommodates legacy 5V logic and high-voltage analog front-ends |
| Charge Injection | ±1pC typ - reduces hold-step error in sample-and-hold circuits without requiring large compensation capacitors |
| OFF Isolation | 60dB at 1MHz - suppresses crosstalk between adjacent channels in multi-signal routing applications |
| Logic Compatibility | TTL and CMOS - interfaces directly with microcontrollers, FPGAs, and legacy logic without level-shifting |
Pinout & Package
16-pin SOIC (M16.15) package with exposed substrate connection on Pin 13 (V+). Pin 12 is NC. All analog I/O pins are bidirectional and symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Active-high logic controls: HIGH disables corresponding switch (DG441 logic polarity) |
| 2, 7, 10, 15 | D1–D4 | Drain terminals - output side of each SPST switch, fully bidirectional |
| 3, 6, 11, 14 | S1–S4 | Source terminals - input side of each SPST switch, fully bidirectional |
| 4 | V− | Negative supply rail - must be ≤ −25V relative to GND for absolute max rating compliance |
| 5 | GND | Logic common reference - separate from analog ground but tied internally to substrate bias |
| 13 | V+ | Positive supply and substrate connection - sets channel threshold and defines max analog swing |
Key Features
| Feature | Design Value |
|---|---|
| Bilateral analog switching | Identical rDS(ON) and capacitance in both directions - eliminates signal path asymmetry in AC-coupled audio or instrumentation |
| Low charge injection (±1pC) | Reduces hold-mode voltage step in sample-and-hold circuits to <1mV with 1nF hold capacitor |
| No latch-up risk | Epitaxial isolation layer prevents destructive latch-up even under transient overvoltage or ESD stress |
| Drop-in upgrade path | Pins, footprint, and timing compatible with DG201A/DG202 - allows direct replacement without PCB revision |
| Wide supply flexibility | Operates from +5V single supply up to ±22V split - supports mixed-signal systems with disparate voltage domains |

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 |
|---|---|---|---|
| MAX4618ESE+ | Lower rDS(ON) (45Ω typ), higher supply current (120μA), only ±15V dual-supply rated | Better for low-distortion audio; unsuitable for >±15V or >34V single-supply operation | Select when lower ON resistance is critical and supply rails are constrained to ±15V or less |
| ADG1412BRUZ | Higher speed (tON = 120ns), wider temp range (−40°C to +125°C), but requires external Vlogic reference | Preferred for automotive or extended-temp industrial designs; needs additional bias circuitry | Choose for high-reliability environments demanding extended temperature operation and faster switching |
Compared with DG441EEE, MAX4618ESE+ offers lower conduction loss but sacrifices supply flexibility, while ADG1412BRUZ provides superior speed and temperature range at the cost of added system complexity and higher BOM count.

FAQ
What is the logic polarity of DG441EEE?
The DG441EEE uses active-high logic control: applying a logic HIGH (≥2.4V) to any INx pin turns the corresponding switch OFF, while a LOW (≤0.8V) turns it ON. This is the inverse of the DG442 series and matches the behavior of legacy DG201A devices, making DG441EEE a direct drop-in replacement in existing designs using that logic convention.
Does DG441EEE support single-supply operation?
Yes, DG441EEE supports single-supply operation from +5V to +34V. When operated with V− = 0V, its analog signal range is 0V to V+, e.g., 0–12V with a +12V supply. The device maintains functional integrity and specified leakage performance across this full range, confirmed in the Electrical Specifications table for single-supply test conditions.
What is the maximum analog signal voltage DG441EEE can handle?
DG441EEE supports a maximum analog signal range of ±20V, limited by its absolute maximum ratings: GND to V+ ≤ +34V and GND to V− ≥ −25V. With ±15V supplies, the guaranteed linear operating range is ±15V; exceeding ±20V risks exceeding internal junction limits and is not supported per datasheet specifications.
Is DG441EEE RoHS compliant?
Yes, DG441EEE is RoHS compliant and available in Pb-free versions (e.g., DG441DYZ, DG441DVZ). These variants use 100% matte tin plating and meet IPC/JEDEC J-STD-020 reflow profiles. The "EEE" suffix in DG441EEE corresponds to Intersil's standard SOIC packaging with RoHS-compliant materials and processing.
How does DG441EEE compare to DG201A in performance?
DG441EEE improves upon DG201A with lower ON resistance (<85Ω vs. ~100Ω), faster switching (tON <250ns vs. ~400ns), reduced charge injection (±1pC vs. ±5pC), and enhanced latch-up immunity due to its epitaxial silicon-gate process. All pinouts, footprints, and logic levels remain identical, enabling seamless replacement without layout changes.
