Product details
Overview
The MAX4525EUB+T from Maxim Integrated is a low-voltage, single-supply, double-pole/double-throw (DPDT) analog switch configured for bidirectional signal routing in battery-powered and low-noise systems. It operates from +2V to +12V, delivers 200Ω on-resistance at +5V, supports rail-to-rail analog signals, and features 2nA max off-leakage at +25°C - enabling precision signal switching in audio, data-acquisition, and communications circuits.
For engineers reviewing the MAX4525EUB+T datasheet, MAX4525EUB+T pinout, MAX4525EUB+T application, or MAX4525EUB+T equivalent, key selection criteria include guaranteed 8Ω on-resistance matching between poles, TTL/CMOS-compatible logic thresholds (0.8V–2.4V), inhibit-controlled simultaneous channel disable, break-before-make timing (5ns typ), and µMAX-10 package compatibility with space-constrained PCB layouts.
Technical Context
The MAX4525EUB+T implements a fully CMOS-based DPDT architecture with two independent SPDT sections (COMA/NOA/NCA and COMB/NOB/NCB), each controlled by dual address inputs (ADDA, ADDB) and a shared inhibit (INH) terminal. Its internal logic translates TTL/CMOS-level inputs into full-rail gate drive for analog pass transistors, eliminating external level-shifting requirements.
All analog terminals (COM, NO, NC) are bidirectional and interchangeable; no ground reference is required for analog paths. ESD protection diodes connect each analog pin to V+ and GND, limiting signal excursion to the supply rails and defining leakage behavior as a function of VCOM position and temperature - with off-leakage specified at 2nA (+25°C) and 20nA (+85°C).
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 auxiliary rails. |
| On-Resistance (RON) | 200Ω at +5V - ensures minimal signal attenuation and voltage drop in precision analog paths. |
| On-Resistance Match | ≤8Ω between channels at +5V - critical for matched gain/phase in differential or dual-channel routing. |
| Off-Leakage Current | 2nA max at +25°C - preserves signal integrity in high-impedance sensor or sample-hold circuits. |
| Logic Thresholds | 0.8V low / 2.4V high at +5V - guarantees interoperability with standard TTL and CMOS digital controllers. |
| Break-Before-Make Time | 5ns typical - prevents momentary short-circuiting during pole transition in relay-replacement applications. |
| Charge Injection | 0.8pC typical - minimizes voltage glitch on sampled nodes in data-acquisition front-ends. |
Pinout & Package
MAX4525EUB+T uses a 10-pin µMAX package (3mm × 3mm, 0.5mm pitch), thermally enhanced with an 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 | Switched output/input for pole A; connects to COMA when enabled. |
| 2 (COMA) | Analog "A" Common | Center node for pole A; bidirectional path between NOA and NCA. |
| 3 (NCA) | Analog "A" Normally Closed | Switched output/input for pole A; connects to COMA when INH = low and ADD = 0. |
| 4 (INH) | Inhibit Control | Active-high global disable: forces all switches open regardless of address state. |
| 5 (GND) | Digital Ground Reference | Reference for logic inputs only; analog paths are ground-free and rail-to-rail. |
| 6 (ADDB) | Address Input B | MSB control bit for DPDT configuration; selects NOB/NCA vs. NOB/NCB pairing. |
| 7 (ADDA) | Address Input A | LSB control bit; determines connection state of each pole (NO/NC) per truth table. |
| 8 (NOB) | Analog "B" Normally Open | Switched output/input for pole B; connects to COMB when enabled. |
| 9 (COMB) | Analog "B" Common | Center node for pole B; bidirectional path between NOB and NCB. |
| 10 (V+) | Positive Supply | Powers analog switches and logic; also ties exposed thermal pad for improved power dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog operation | Supports input/output signals from GND to V+ without clipping - essential for full-scale ADC/DAC interfacing. |
| Guaranteed on-resistance match | ≤8Ω max difference between COMA-NOA and COMA-NCA at +5V - enables accurate differential signal routing. |
| Inhibit-controlled shutdown | Single-pin global disable opens all paths simultaneously - simplifies power sequencing and fault isolation. |
| TTL/CMOS logic compatibility | 0.8V–2.4V thresholds at +5V eliminate need for level shifters when driven by microcontrollers or FPGAs. |

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+ | Same die, TDFN-EP (3mm × 3mm) package with exposed thermal pad - 1951mW max power dissipation vs. 330mW for µMAX. | Better thermal performance in high-duty-cycle or high-current routing; requires different land pattern and solder stencil. | Select MAX4525ETB+ for >10mA continuous channel current or ambient >70°C; otherwise µMAX offers smaller footprint. |
| TMUX6219RSVR | 10-bit, 2:1 DPDT switch with 3.5Ω typical RON, ±16.5V supply range, and 1.5pC charge injection - higher performance but larger 16-pin WQFN. | Supports bipolar analog signals and higher voltage rails; not drop-in compatible due to pin count, layout, and logic interface differences. | Choose TMUX6219RSVR only when RON <5Ω or dual-supply operation is mandatory; MAX4525EUB+T remains optimal for cost-sensitive, low-voltage, space-constrained designs. |
Compared with MAX4525ETB+, the MAX4525EUB+T trades thermal headroom for board area savings; versus TMUX6219RSVR, it provides proven reliability and lower system cost in 3.3V/5V battery-operated applications where sub-5Ω RON is unnecessary.

FAQ
What is the maximum operating temperature range for the MAX4525EUB+T?
The MAX4525EUB+T is rated for operation from -40°C to +85°C, as confirmed in the Ordering Information table of the official datasheet (Rev 2). This extended temperature grade (denoted by the 'E' suffix) ensures reliable performance in industrial and automotive-adjacent environments where ambient conditions exceed commercial-grade limits. The device maintains specified on-resistance, leakage, and switching timing across this full range.
Does the MAX4525EUB+T require a dual supply or ground reference for analog signals?
No, the MAX4525EUB+T operates from a single supply (V+ and GND) and does not require a ground reference for analog signal paths. As stated in the Applications Information section, "There is no connection between the analog signal paths and GND." Analog signals can swing rail-to-rail (GND to V+) bidirectionally, making the MAX4525EUB+T ideal for floating or isolated signal chains where ground loops must be avoided.
How does the inhibit (INH) pin function on the MAX4525EUB+T?
The INH pin on the MAX4525EUB+T is an active-high global disable input. When pulled high (≥2.4V at +5V supply), it forces all internal switches into the open state - disconnecting COMA from NOA/NCA and COMB from NOB/NCB regardless of ADDA/ADDB logic states. This feature enables fast system-level fault response, power-down sequencing, or safe startup initialization without altering address control lines.
Can the MAX4525EUB+T be used with a +3V supply, and what performance changes occur?
Yes, the MAX4525EUB+T is fully specified for +3V operation (2.7V to 3.6V range). At +3V, on-resistance increases to 500Ω (vs. 200Ω at +5V), turn-on/off times lengthen (e.g., t(ON) = 400ns typ), and logic thresholds shift to 0.5V (low) and 2.0V (high). These trade-offs are documented in the Electrical Characteristics tables for +3V supply and remain within guaranteed limits for portable, low-power applications.
Is the MAX4525EUB+T pin-compatible with the MAX4524 series?
No, the MAX4525EUB+T is not pin-compatible with the MAX4524 series. Although both use the same 10-pin µMAX package, their pinouts differ fundamentally: the MAX4524 is a 4:1 multiplexer (COM, NO0–NO3, ADDA/ADDB, INH, GND, V+) while the MAX4525EUB+T is a DPDT switch (COMA/NCA/NOA, COMB/NCB/NOB, ADDA/ADDB, INH, GND, V+). Swapping them would result in incorrect signal routing and potential functional failure.
