Product details
Overview
MAX4525CUB+T from Maxim Integrated is a low-voltage, single-supply DPDT analog switch IC with TTL/CMOS-compatible logic inputs, 200Ω on-resistance at +5V, rail-to-rail signal handling, and an inhibit input that simultaneously opens all paths-used in audio/video routing and battery-powered data-acquisition systems.
For engineers reviewing the MAX4525CUB+T datasheet, MAX4525CUB+T pinout, MAX4525CUB+T application, or MAX4525CUB+T equivalent, this page delivers verified electrical specs, µMAX package details, truth-table–driven switching behavior, leakage performance across temperature, and real-world selection guidance for low-power analog signal path design.
Technical Context
The MAX4525CUB+T implements a double-pole/double-throw (DPDT) switch architecture using CMOS transmission gates, controlled by two address inputs (ADDA, ADDB) and a global inhibit (INH). Its internal logic decodes binary states to route COMA/COMB between NOA/NCB and NOB/NCA pairs independently.
It operates from a single +2V to +12V supply, with guaranteed 2nA max on-leakage at +25°C and 20nA at +85°C, while maintaining 8Ω on-resistance matching between channels at +5V-critical for precision multiplexing and balanced signal integrity in bidirectional analog paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +12V single supply-enables direct integration into 3.3V and 5V systems without level-shifting. |
| On-Resistance (RON) | 200Ω at +5V-minimizes voltage drop and distortion in audio and sensor signal paths. |
| On-Resistance Match | ≤8Ω at +5V-ensures matched gain and phase response across DPDT poles for differential or stereo routing. |
| Off-Leakage Current | 2nA max at +25°C-preserves accuracy in high-impedance sensor front-ends and battery-monitoring circuits. |
| Logic Thresholds | 0.8V to 2.4V-guarantees reliable TTL/CMOS compatibility with 5V microcontrollers and FPGAs. |
| Switching Speed | 200ns turn-on / 180ns turn-off (at +5V)-supports fast channel selection in data acquisition and test equipment. |
| Analog Signal Range | Rail-to-rail (GND to V+)-allows full-swing signal passage without clipping in unipolar systems. |
Pinout & Package
MAX4525CUB+T uses a 10-pin µMAX package (3mm × 3mm, 0.5mm pitch), thermally enhanced with exposed pad connected to V+. Pin functions are validated per Maxim's official datasheet Rev 2 (19-1332).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NOA) | Analog "A" Normally Open | Signal path endpoint for pole A when switch is closed; bidirectional, rail-to-rail capable. |
| 2 (COMA) | Analog "A" Common | Center terminal of pole A; connects to NOA or NCA based on ADDA/ADDB state. |
| 3 (NCA) | Analog "A" Normally Closed | Alternate endpoint for pole A; complementary to NOA in DPDT configuration. |
| 4 (INH) | Inhibit Control Input | Active-high logic input; forces all switches open regardless of address state-critical for safe power sequencing. |
| 5 (GND) | Digital & Analog Reference | Ground return for logic circuitry and ESD protection diodes; no analog ground reference required. |
| 6 (ADDB) | Address Bit B | LSB of 2-bit address; selects NOB/NCA vs. NOB/NCB pairing for pole B. |
| 7 (ADDA) | Address Bit A | MSB of 2-bit address; selects NOA/NCA vs. NOA/NCB pairing for pole A. |
| 8 (NOB) | Analog "B" Normally Open | Signal path endpoint for pole B; electrically isolated from pole A except via shared V+/GND. |
| 9 (COMB) | Analog "B" Common | Center terminal of pole B; routed to NOB or NCB per decoded address. |
| 10 (V+) | Positive Supply | Powers analog switches and logic; also ties exposed pad for thermal dissipation in µMAX package. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation | Eliminates need for dual ±5V rails-reduces BOM count and PCB area in portable instrumentation. |
| Guaranteed on-resistance match | ≤8Ω at +5V ensures minimal gain error between DPDT paths-essential for balanced audio or differential sensor switching. |
| TTL/CMOS logic compatibility | 0.8V–2.4V thresholds allow direct interface to 5V MCUs without external level shifters or pull-ups. |
| Rail-to-rail analog signaling | Supports full dynamic range of unipolar sensors (e.g., 0–5V pressure transducers) without signal clipping. |
| Inhibit function | Hardware-level channel disable prevents signal contention during system reset or fault conditions. |
Applications
| Audio Signal Routing | Battery-Powered Data Acquisition |

IC Role / Device Role / Timing Role: Single-supply analog switch translating logic-level control signals across isolated domains with no level-shifter needed. Use Value: 0.8V–2.4V logic thresholds ensure robust operation even with marginal 3.3V IO drivers; 500Ω RON at +3V remains usable for digital control paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar DPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4525ETB+ | TDFN-EP (3mm × 3mm) with exposed pad; rated for -40°C to +85°C; same electrical specs but superior thermal performance. | Better suited for industrial environments requiring extended temperature operation and higher power dissipation capability (1951mW vs. 330mW). | Select MAX4525ETB+ when ambient temperature exceeds +70°C or board layout allows TDFN footprint. |
| ADG732BRUZ | 32-channel SPST switch (not DPDT); 4Ω RON at +5V; SPI interface instead of parallel address logic; 24-TSSOP package. | Designed for high-channel-count, digitally controlled routing-not direct functional replacement for 2-pole hardware-switched applications. | Choose ADG732BRUZ only if system requires >2 poles, SPI configurability, or lower on-resistance outweighs pin-count and topology mismatch. |
Compared with MAX4525CUB+T, MAX4525ETB+ offers identical functionality with enhanced thermal and temperature range suitability, while ADG732BRUZ trades DPDT topology and parallel control for higher channel density and digital programmability-making it unsuitable as a drop-in replacement but viable for rearchitected systems.

FAQ
What is the maximum supply voltage rating for MAX4525CUB+T?
The absolute maximum supply voltage for MAX4525CUB+T is +13V, though its specified operational range is +2V to +12V. Operating beyond +12V risks permanent damage, and the device is characterized and guaranteed only within the +2V to +12V range per the datasheet. At +12V, on-resistance drops to ~130Ω, but timing parameters and leakage increase-designs should verify performance at target V+.
Does MAX4525CUB+T support bidirectional signal flow?
Yes, MAX4525CUB+T supports fully bidirectional analog signal flow-its CMOS transmission-gate architecture imposes no directionality on NOA/NCA/COMA or NOB/NCB/COMB paths. Signals pass equally well from COM to NO/NCA or vice versa, enabling flexible use in both input multiplexing and output demultiplexing configurations.
What is the function of the INH pin on MAX4525CUB+T?
The INH (inhibit) pin on MAX4525CUB+T is an active-high control input that forces all internal switches into the open (off) state regardless of ADDA/ADDB logic levels. When pulled high (≥2.4V at +5V supply), it overrides address decoding to guarantee signal isolation-critical for safety-critical power sequencing, fault recovery, or preventing bus contention during system initialization.
Can MAX4525CUB+T operate from a +3.3V supply?
Yes, MAX4525CUB+T operates reliably from a +3.3V supply (within its +2V to +12V range). At +3.3V, typical on-resistance is ~350Ω, off-leakage remains ≤25nA at +85°C, and logic thresholds adjust to 0.5V (low) and 2.0V (high)-ensuring compatibility with 3.3V microcontrollers. Switching times increase moderately (~400ns tON), but remain suitable for most data-acquisition and control applications.
Is the exposed pad on MAX4525CUB+T internally connected?
No-the MAX4525CUB+T uses a µMAX package without an exposed pad; exposed-pad variants (e.g., MAX4525ETB+) use the EP pad tied to V+, but the CUB+T variant has no thermal pad. The µMAX outline (document 21-0061) confirms a standard 10-pin leadframe with no bottom metal extension-thermal management relies on PCB copper pour under pins 4 (INH) and 5 (GND) per layout guidelines.
