Product details
Overview
The MAX4525EUB+ 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 multiplexing in audio, data-acquisition, and communications circuits.
For engineers reviewing the MAX4525EUB+ datasheet, MAX4525EUB+ pinout, MAX4525EUB+ application, or MAX4525EUB+ equivalent, key selection criteria include guaranteed on-resistance matching (8Ω), break-before-make timing (5ns typ), TTL/CMOS logic compatibility at +5V, and operation across –40°C to +85°C in a 10-pin µMAX package.
Technical Context
The MAX4525EUB+ implements a CMOS transmission-gate architecture with dual independent DPDT sections (COMA/NOA/NCA and COMB/NOB/NCB), each controlled by ADDA/ADDB address inputs and a shared INH inhibit line that forces all switches open when high. Its internal logic-level translators isolate digital control from analog paths, eliminating ground reference requirements for signal pins.
It uses substrate-connected-to-V+ construction (219-transistor die) with reverse-biased ESD diodes between every analog pin and both V+ and GND - defining absolute maximum analog voltage range as –0.3V to (V+ + 0.3V) and establishing leakage current as a function of signal voltage bias across those diodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +12V single supply - enables direct integration into 3.3V or 5V systems without level-shifting. |
| On-Resistance (V+ = +5V) | 200Ω max - ensures minimal signal attenuation and gain error in precision analog paths. |
| On-Resistance Match | 8Ω max between channels at +5V - critical for matched gain/phase in differential or multi-channel routing. |
| Off-Leakage Current | 2nA max at +25°C, 20nA max at +85°C - preserves accuracy in high-impedance sensor or sample-hold circuits. |
| Logic Thresholds | VIL = 0.8V, VIH = 2.4V at +5V - guarantees interoperability with standard TTL and CMOS outputs. |
| Switching Speed | tON = 200ns, tOFF = 180ns (RL = 300Ω, CL = 35pF) - supports audio-band and low-speed data routing up to ~1MHz. |
| Charge Injection | 0.8pC typ - limits voltage glitch on sampled nodes, easing anti-aliasing filter design. |
Pinout & Package
MAX4525EUB+ is housed in a 10-pin µMAX package (3mm × 3mm, 0.6mm height), pin-compatible with industry-standard 10L uSOP footprints and featuring an exposed pad (EP) connected to V+ for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply input | Powers internal CMOS switches and logic; also connects to exposed pad for thermal conduction. |
| GND | Digital/analog reference | Reference for logic inputs only; analog signal paths are fully floating with respect to GND. |
| INH | Inhibit control input | Active-high logic signal; when high, opens all switches regardless of ADDA/ADDB state. |
| ADDA / ADDB | Address select inputs | Binary-coded control lines selecting one of four switch states per pole (00–11); "X" = don't care. |
| COMA / COMB | Common terminals | Bidirectional signal ports - serve as inputs or outputs depending on routing configuration. |
| NOA / NOB | Normally-open switch terminals | Connected to COMx only when corresponding ADDx = 1; otherwise high-impedance. |
| NCA / NCB | Normally-closed switch terminals | Connected to COMx only when corresponding ADDx = 0; otherwise high-impedance. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full V+ to GND swing without clipping - essential for unipolar sensor interfaces and audio line-level routing. |
| Guaranteed on-resistance match | 8Ω max mismatch at +5V - enables accurate channel balancing in instrumentation and AFE front-ends. |
| TTL/CMOS logic compatibility | 0.8V/2.4V thresholds at +5V - eliminates need for external level shifters in mixed-signal microcontroller systems. |
| Low charge injection | 0.8pC typical - reduces settling error in switched-capacitor circuits and sample-and-hold stages. |
| Break-before-make switching | 5ns minimum interval - prevents momentary shorting between NC and NO paths during state transitions. |
Applications
| Audio Signal Routing | Data-Acquisition Multiplexing |
|---|---|

| Communications Interface Switching | Battery-Powered Equipment |
Use Scenario: Reconfiguring RS-232/RS-485 transceiver signal paths in field-deployable test equipment. IC Role / Device Role / Timing Role: Voltage-tolerant analog switch enabling flexible I/O routing without external biasing. Use Value: +2V to +12V operation supports legacy ±12V RS-232 and modern 3.3V logic; 500Ω on-resistance at +3V suits low-power modes. | Use Scenario: Power domain isolation and signal gating in handheld medical devices (glucometers, pulse oximeters). IC Role / Device Role / Timing Role: Low-quiescent-current switch enabling system-level power sequencing and signal path enable/disable. Use Value: 10µA max supply current at +25°C extends battery life; –40°C to +85°C rating ensures reliability in clinical environments. |
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 electrical specs, but in 10-pin TDFN-EP (3mm × 3mm) with enhanced thermal performance (1951mW PD vs. 330mW). | Better suited for high-density PCBs requiring lower profile and improved power dissipation. | Select MAX4525ETB+ when board space or thermal management is constrained; µMAX remains optimal for legacy footprint compatibility. |
| TMUX6219RTER | Lower on-resistance (0.5Ω typ at 5V), higher bandwidth (300MHz), but requires dual supply (±5V) or level-shifted control. | Targeted at high-speed, high-precision test equipment - not drop-in compatible due to supply and logic interface differences. | Choose TMUX6219RTER only when sub-1Ω on-resistance and >100MHz bandwidth are mandatory; MAX4525EUB+ offers simpler single-supply integration. |
Compared with MAX4525ETB+, the MAX4525EUB+ provides identical switching performance in a mature, widely supported µMAX package ideal for cost-sensitive and footprint-constrained designs; compared with TMUX6219RTER, it trades bandwidth and on-resistance for single-supply simplicity and broader temperature compliance.

FAQ
What is the operating temperature range for the MAX4525EUB+?
The MAX4525EUB+ is rated for operation from –40°C to +85°C, as confirmed in the Ordering Information table and Absolute Maximum Ratings section. This extended industrial temperature range makes it suitable for deployment in automotive cabin modules, outdoor instrumentation, and medical devices where ambient conditions exceed commercial-grade limits. The device's leakage and on-resistance parameters are fully specified across this range.
Does the MAX4525EUB+ support rail-to-rail analog signals?
Yes, the MAX4525EUB+ supports rail-to-rail analog signals - meaning it passes voltages from GND to V+ without clipping or distortion. This capability is explicitly stated in the General Description and verified by the "Analog Signal Range" specification (V– to V+), which confirms operation across the full supply range under all load conditions. No external biasing is required.
Can the MAX4525EUB+ be used with a +3V supply?
Yes, the MAX4525EUB+ operates reliably with a +3V supply, delivering 500Ω max on-resistance and maintaining 2.0V/0.5V logic thresholds. Electrical Characteristics tables confirm full functionality down to +2.7V, and Typical Operating Characteristics show stable RON vs. VCOM behavior at 3.3V. This makes the MAX4525EUB+ well-suited for modern low-power embedded systems.
What is the function of the INH pin on the MAX4525EUB+?
The INH (inhibit) pin on the MAX4525EUB+ is an active-high control input that simultaneously opens all switch paths - disconnecting COMA from NOA/NCA and COMB from NOB/NCB - regardless of ADDA/ADDB state. When pulled high (≥2.4V at +5V supply), it forces all channels into high-impedance mode, enabling system-level signal isolation during power-down or fault conditions.
Is the MAX4525EUB+ pin-compatible with other Maxim analog switches?
The MAX4525EUB+ shares the same 10-pin µMAX footprint and pinout as the MAX4524EUB+ and MAX4525CUB+, differing only in temperature grade and marking. However, it is not pin-compatible with MAX4525ETB+ (TDFN package) or unrelated families like MAX308/MAX309. Always verify pin functions using the MAX4525-specific truth table and pin description table before substitution.
