Product details
Overview
DG441CY from Maxim Integrated is a quad, normally-closed (NC), single-pole/single-throw (SPST) analog switch IC designed for precision signal routing in rail-to-rail, 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 operates from ±4.5V to ±20V or +10V to +30V supplies - used in test equipment and audio-signal routing where channel consistency and low distortion are critical.
For engineers reviewing the DG441CY datasheet, DG441CY pinout, DG441CY application, or DG441CY equivalent, this page delivers verified electrical parameters, package-specific terminal mapping, real-world use cases, and validated alternative parts - all confirmed against Maxim's official 19-4611 Rev 5 datasheet and SO-16 packaging documentation.
Technical Context
The DG441CY implements four independent NC SPST switches using a 44V silicon-gate process, enabling rail-to-rail analog signal handling up to ±15.5V with guaranteed on-resistance flatness (9Ω max) over full signal range under bipolar operation. Its TTL/CMOS-compatible logic inputs drive internal gate structures that maintain symmetric conduction regardless of signal polarity.
Switching performance is characterized by tON < 250ns and tOFF < 170ns (at ±15V), supported by low dynamic power (1.65mW max) and ESD tolerance ≥2000V per Method 3015.7. Off-isolation rejection ratio exceeds 60dB at 1MHz, and crosstalk between any two channels remains ≤–100dB - confirming suitability for high-fidelity multiplexing in communication systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (rDS(ON)) | 85Ω max - ensures minimal voltage drop and signal attenuation across full analog range (±15.5V) at +25°C. |
| On-Resistance Match | 4Ω max - guarantees consistent gain/attenuation across all four channels, critical for multi-channel instrumentation. |
| Charge Injection | 10pC max - limits voltage glitch at sample-hold nodes, enabling accurate DC-coupled acquisition in sample-and-hold circuits. |
| Off-Leakage Current | <5nA at +85°C - preserves signal integrity in high-impedance sensor interfaces and battery-operated systems over temperature. |
| Supply Range | ±4.5V to ±20V or +10V to +30V - supports flexible system-level power architecture without external level-shifting. |
| Switching Time (tON/tOFF) | <250ns / <170ns - enables fast channel selection in automated test equipment and real-time signal routing. |
| ESD Tolerance | ≥2000V per Method 3015.7 - provides robust handling during board assembly and field service without added protection circuitry. |
Pinout & Package
DG441CY is supplied in a 16-pin narrow SO (Small Outline) package with gull-wing leads, JEDEC MS-012AC compliant, 7.5mm body width, and exposed pad connected to V+ per Maxim's recommendation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 4, 7, 10, 11, 14, 15 | S1–S4, IN1–IN4 | Source terminals (S1–S4) and digital control inputs (IN1–IN4); S pins carry analog signals, IN pins accept TTL/CMOS logic. |
| 2, 13, 16, 5, 6, 8, 9, 12 | D1–D4, V+, V-, GND, N.C. | Drain terminals (D1–D4) connect to load side; V+ and V- supply rails; GND is reference; Pin 12 is not internally connected. |
| 12 | N.C. | No internal connection - must be left floating or tied to ground per layout best practice; not usable as signal or supply path. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V– to V+ (±15.5V), eliminating clipping in wide-dynamic-range audio and sensor front-ends. |
| Guaranteed rFLAT(ON) ≤9Ω | Ensures uniform gain error across input voltage range - essential for precision measurement and calibration systems. |
| TTL/CMOS logic compatibility | Accepts standard 0.8V/2.4V thresholds without level shifters, simplifying interface with microcontrollers and FPGAs. |
| Low power consumption (1.65mW) | Reduces thermal load and extends battery life in portable test gear and handheld guidance systems. |
| Improved off-leakage <5nA @ +85°C | Maintains accuracy in high-impedance medical sensors and aerospace telemetry where leakage-induced drift is unacceptable. |
Applications
| Test Equipment | Audio-Signal Routing |
|---|---|
Use Scenario: Automated test systems switching between multiple DUTs and measurement instruments. IC Role / Device Role / Timing Role: Quad NC SPST switch isolating signal paths during reconfiguration; logic-controlled channel enable/disable.

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 |
|---|---|---|---|
| ADG441BRZ | 80Ω max rDS(ON), 15pC charge injection, −40°C to +85°C rating, same SO-16 footprint. | Higher charge injection limits use in precision sample-and-hold; wider temp range suits industrial deployment. | Select ADG441BRZ when extended temperature operation is required and 15pC injection is acceptable for target signal bandwidth. |
| TS5A4624DCKR | 0.7Ω typical rDS(ON), 3.3V-only supply, 12-bit ENOB limit, smaller SC70-6 package (single channel). | Not quad or pin-compatible; requires four devices and PCB redesign; unsuitable for ±15V systems. | Choose TS5A4624DCKR only for low-voltage, high-speed (<100ns) single-channel routing where ultra-low on-resistance is mandatory. |
Compared with DG441CY, ADG441BRZ offers broader temperature support but higher charge injection, while TS5A4624DCKR delivers lower on-resistance at the cost of supply voltage limitation and non-quad integration - making DG441CY optimal for bipolar-rail, multi-channel, medium-speed precision routing.

FAQ
What is the operating temperature range for DG441CY?
The DG441CY is rated for 0°C to +70°C ambient operation, as specified in Maxim's ordering information table. This commercial-grade temperature range aligns with its narrow SO packaging and targets applications such as test equipment and audio routing where environmental control is maintained. The DG441DY variant extends to –40°C to +85°C for industrial use, but DG441CY itself is not qualified beyond +70°C.
Is DG441CY pin-compatible with the original DG441 series?
Yes, DG441CY maintains identical pinout and electrical behavior with legacy DG441 variants in the same narrow SO package, including DG441C/D and DG441MY/PR. All share the same 16-pin SO layout, NC pin (Pin 12), and terminal assignments for S1–S4, D1–D4, IN1–IN4, V+, V–, GND, and N.C. - enabling direct replacement without PCB modification.
Does DG441CY support single-supply operation?
Yes, DG441CY supports single-supply operation from +10V to +30V, with V– connected to ground. In this configuration, the analog signal range spans 0V to V+, enabling compatibility with microcontroller-based systems and battery-powered devices. Performance metrics like rDS(ON) and leakage remain within datasheet limits, though on-resistance increases slightly versus bipolar operation.
What is the maximum analog signal voltage DG441CY can handle?
DG441CY supports analog signals from V– to V+, with absolute maximum ratings allowing VD and VS up to ±15.5V when operated at ±16.5V supplies. Under standard ±15V conditions, the guaranteed rail-to-rail range is ±15V - meaning signals from –15V to +15V pass through with minimal distortion, provided supply sequencing and external protection diodes (if used) are correctly implemented.
How does DG441CY differ from DG442CY?
DG441CY is a normally closed (NC) quad SPST switch, while DG442CY is normally open (NO). Their pinouts and electrical specs are identical except for logic polarity: DG441CY conducts when IN = 0V (logic low), whereas DG442CY conducts when IN = 2.4V (logic high). Both share the same rDS(ON), leakage, charge injection, and supply specifications - making them functionally complementary rather than interchangeable.
