Product details
Overview
DG441ETE+ from Maxim Integrated is a quad, normally closed (NC), single-pole/single-throw (SPST) analog switch IC designed for precision signal routing in bipolar or single-supply systems. It features 85Ω max on-resistance, 4Ω max on-resistance matching between channels, <5nA off-leakage at +85°C, 10pC max charge injection, and rail-to-rail analog signal handling up to ±15.5V with ±15V supplies.
For engineers reviewing the DG441ETE+ datasheet, DG441ETE+ pinout, DG441ETE+ application, or DG441ETE+ equivalent, key selection criteria include guaranteed rFLAT(ON) ≤9Ω over signal range, TTL/CMOS logic compatibility, ESD tolerance ≥2000V (Method 3015.7), and operation across -40°C to +85°C industrial temperature range.
Technical Context
The DG441ETE+ uses a 44V silicon-gate process to support wide supply ranges: ±4.5V to ±20V bipolar or +10V to +30V single supply. Its four independent NC switches exhibit symmetrical conduction, low power consumption (1.65mW max), and matched channel performance critical for multiplexer and sample-and-hold accuracy.
Switching is controlled by active-low logic inputs (IN1–IN4), with propagation delays under 250ns tON and 170ns tOFF. Internal protection diodes clamp analog signals exceeding V+ or V−, and the exposed pad (EP) must be connected to V+ for thermal and electrical integrity in the Thin QFN package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (rDS(ON)) | 85Ω max - ensures minimal signal attenuation and voltage drop in precision analog paths |
| On-Resistance Matching | 4Ω max - enables accurate channel-to-channel signal amplitude consistency in multiplexed systems |
| On-Resistance Flatness | 9Ω max - guarantees stable rDS(ON) across full analog input range (±15.5V), reducing harmonic distortion |
| Charge Injection | 10pC max - minimizes sampling errors and pedestal shift in sample-and-hold and ADC front-end circuits |
| Off-Leakage Current | <5nA at +85°C - preserves signal integrity in high-impedance sensor interfaces and battery-powered systems |
| Supply Range | ±4.5V to ±20V bipolar or +10V to +30V single - supports flexible system-level power architecture without level-shifting |
| ESD Tolerance | 2000V min (HBM, Method 3015.7) - enhances robustness during board handling and system integration |
Pinout & Package
Package: 16-pin Thin QFN-EP (5mm × 5mm), exposed pad (EP) requiring connection to V+ for optimal thermal performance and electrical stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Logic control input (active-low) | Drives corresponding switch ON (closed) when logic low; inverted logic sense per DG441 function |
| D1–D4 | Analog drain terminal | One side of SPST switch; bidirectional signal path with Sx terminals |
| S1–S4 | Analog source terminal | Other side of SPST switch; connects to Dn when switch is closed (NC configuration) |
| V+ | Positive supply input | Bias for internal circuitry and substrate; EP must be tied to this node |
| V− | Negative supply input | Required for bipolar operation; connect to GND for single-supply mode |
| GND | Ground reference | Logic ground and return path; separate from analog signal ground in mixed-signal layouts |
| N.C. | Not internally connected | No internal bond; must be left floating or grounded per PCB layout best practices |
| EP | Exposed thermal pad | Must be soldered to V+ plane for thermal dissipation and reduced package inductance |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports ±15.5V signals with ±15V supplies - eliminates need for external clamping in wide-dynamic-range applications |
| TTL/CMOS logic compatible inputs | Accepts 0.8V/2.4V thresholds - enables direct interfacing with microcontrollers and FPGAs without level shifters |
| Low power consumption | 1.65mW max at +25°C - extends battery life in portable test equipment and handheld instrumentation |
| Guaranteed performance over temperature | rDS(ON), leakage, and switching times specified from -40°C to +85°C - ensures reliability in industrial environments |
| Improved off-leakage vs legacy DG441 | <5nA at +85°C (vs >20nA in earlier versions) - reduces drift in high-impedance sensor multiplexing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG441BRUZ | Quad NC SPST; 75Ω rDS(ON) max, 25nA off-leakage at +85°C, no exposed pad | Higher leakage limits use in high-Z sensor arrays; lacks EP for thermal management in high-density layouts | Preferred where lower rDS(ON) is prioritized over leakage and thermal performance |
| TS5A3154DCUR | Single NC SPST; 0.75Ω rDS(ON) max, +1.8V to +5.5V supply only, 30pC charge injection | Not pin-compatible; requires four devices to match DG441ETE+ channel count; unsuitable for ±15V systems | Applicable only in low-voltage, space-constrained designs where ultra-low on-resistance outweighs supply and leakage constraints |
Compared with ADG441BRUZ and TS5A3154DCUR, the DG441ETE+ uniquely balances industrial-grade supply flexibility (±20V), ultra-low leakage (<5nA), and integrated thermal management (EP), making it optimal for precision, high-reliability analog routing where voltage range and long-term stability are critical.

FAQ
What is the operating temperature range for the DG441ETE+?
The DG441ETE+ is rated for industrial operation from -40°C to +85°C. This range is fully characterized for all key parameters including on-resistance, leakage current, switching time, and charge injection-ensuring reliable performance in demanding environments such as factory automation and outdoor test gear where thermal cycling occurs.
Does the DG441ETE+ support single-supply operation?
Yes, the DG441ETE+ supports single-supply operation from +10V to +30V. In this mode, V− must be connected to ground, and the analog signal range extends from 0V to V+ − 0.5V. The device maintains its 85Ω max rDS(ON), 10pC max charge injection, and TTL/CMOS logic compatibility without modification.
What is the purpose of the exposed pad (EP) on the DG441ETE+ Thin QFN package?
The exposed pad (EP) on the DG441ETE+ serves dual thermal and electrical functions: it must be soldered to a V+ copper plane to dissipate heat and reduce junction temperature, and it provides a low-inductance connection to the substrate. It is not a standalone V+ supply path-primary V+ must still be routed to Pin 13-and must never be left floating or grounded.
How does the DG441ETE+ differ from the DG442ETE+?
The DG441ETE+ implements four normally closed (NC) SPST switches, while the DG442ETE+ implements four normally open (NO) SPST switches. Their pinouts, supply specs, and electrical characteristics (rDS(ON), leakage, charge injection) are identical-but logic polarity is inverted: DG441 closes switches on logic low, whereas DG442 closes on logic high. They are not functionally interchangeable without redesigning control logic.
Is the DG441ETE+ pin-compatible with legacy DG441 variants like DG441DJ or DG441DY?
Yes-the DG441ETE+ shares identical pinout, logic behavior, and electrical specifications with other DG441 family members (e.g., DG441DJ, DG441DY), differing only in package (Thin QFN-EP vs. DIP/SO) and lead-free compliance (+ suffix). All share the same 16-pin mapping, IN/D/S/V+/V−/GND/N.C. assignments and operate under identical absolute maximum and recommended conditions.
