Product details
Overview
MAX4541EUA from Maxim Integrated is a precision dual single-pole/single-throw (SPST) analog switch with normally open (NO) configuration, designed for low-voltage, single-supply operation from +2.7V to +12V. It delivers 60Ω max on-resistance, 2Ω max RON matching between channels, and 5pC max charge injection - enabling high-fidelity signal routing in battery-powered instrumentation and portable medical devices.
For engineers reviewing the MAX4541EUA datasheet, MAX4541EUA pinout, MAX4541EUA application, or MAX4541EUA equivalent, key selection criteria include guaranteed break-before-make timing (not applicable), TTL/CMOS logic compatibility, -40°C to +85°C extended temperature operation, µMAX-8 package footprint, and <5µW quiescent power consumption.
Technical Context
The MAX4541EUA implements two independent SPST switches with complementary control inputs (IN1/IN2), each driving its own COM–NO path. Its CMOS transmission-gate architecture ensures bidirectional analog signal handling across the full supply rail (GND to V+), with minimal RON flatness (6Ω max) and low leakage (<10nA at +85°C).
Unlike the MAX4543/MAX4544, the MAX4541EUA lacks break-before-make functionality and NC terminals - it contains only COM1/NO1 and COM2/NO2 pairs. Its logic interface accepts rail-to-rail input voltages, supporting direct interfacing with +3.3V, +5V, or +12V controllers without level shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.7V to +12V single supply - enables direct integration into 3.3V, 5V, and 12V systems without auxiliary rails. |
| On-Resistance (RON) | 60Ω max at +5V - ensures minimal signal attenuation and gain error in precision sensor or DAC/ADC signal paths. |
| RON Matching | 2Ω max between channels - critical for matched gain/phase in differential or dual-channel sampling circuits. |
| Charge Injection | 5pC max - limits voltage glitch on sampled-hold capacitors, preserving ADC accuracy in data acquisition. |
| Leakage Current | 10nA max at +85°C - maintains signal integrity in high-impedance sensor front-ends and battery-monitoring circuits. |
| Switching Speed | tON = 35ns, tOFF = 25ns at +5V - supports >10MHz multiplexing in real-time signal conditioning and test equipment. |
| ESD Protection | 2000V per Method 3015.7 - provides robust handling during board assembly and field service without external protection. |
Pinout & Package
The MAX4541EUA is housed in an 8-pin µMAX package (3.0mm × 3.0mm, 0.8mm height), pin-compatible with industry-standard SO-8 and TDFN-8 variants but with reduced footprint and thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NO1) | Analog Switch 1 - Normally Open terminal | Output node of first SPST switch; connects to COM1 when IN1 = high. |
| 2 (COM1) | Analog Switch 1 - Common terminal | Input/output bidirectional node for first channel; carries full analog signal range (GND to V+). |
| 3 (IN2) | Digital Control Input 2 | Active-high logic input controlling second switch; TTL/CMOS compatible at all supply voltages. |
| 4 (GND) | Ground reference | Return path for supply current and logic threshold reference; must be low-impedance for noise immunity. |
| 5 (NC) | Not internally connected | No internal bond wire; must remain unconnected to avoid parasitic coupling or mechanical stress. |
| 6 (COM2) | Analog Switch 2 - Common terminal | Input/output bidirectional node for second channel; electrically isolated from COM1. |
| 7 (IN1) | Digital Control Input 1 | Active-high logic input controlling first switch; independent timing from IN2 enables asynchronous channel control. |
| 8 (V+) | Positive supply input | Single power rail powering both analog and digital sections; must be bypassed with ≥1µF ceramic capacitor near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Low on-resistance flatness | 6Ω max variation over 0V–V+ signal range - preserves linearity in audio, video, and sensor signal switching. |
| Rail-to-rail analog signal handling | Supports signals from GND to V+ - eliminates need for level-shifting in mixed-voltage systems. |
| TTL/CMOS logic compatibility | Valid at any supply voltage from +2.7V to +12V - simplifies controller interface without external buffers. |
| Ultra-low power consumption | <5µW typical - extends battery life in portable ECG monitors, handheld test meters, and IoT edge nodes. |
| Guaranteed low charge injection | 5pC max - reduces settling time and error in sample-and-hold and switched-capacitor filter applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4541ESA | Same electrical specs; SO-8 package (4.9mm × 6.0mm) vs. µMAX-8 (3.0mm × 3.0mm) | Preferred for through-hole prototyping or legacy PCBs with SO-8 footprints; higher thermal mass but larger area | Select MAX4541ESA when board space allows and hand-soldering or socket-based validation is required. |
| ADG721BRMZ | 3.3V/5V-only supply (1.8V–5.5V); 4Ω typ RON; no 12V operation; 3pC charge injection | Better performance at low voltage; unsuitable for 9V/12V battery or industrial rails where MAX4541EUA operates | Choose ADG721BRMZ for ultra-low-voltage, high-speed portable designs where 12V compatibility is unnecessary. |
Compared with MAX4541ESA and ADG721BRMZ, the MAX4541EUA uniquely balances wide supply range (+2.7V to +12V), compact µMAX packaging, and guaranteed 5pC charge injection - making it optimal for space-constrained, multi-rail industrial and medical systems requiring long-term reliability.

FAQ
What is the operating temperature range for the MAX4541EUA?
The MAX4541EUA is rated for operation from -40°C to +85°C, as confirmed by its "E" grade suffix and ordering information table. This extended temperature range supports deployment in automotive cabin modules, industrial PLCs, and outdoor medical devices where ambient conditions exceed commercial-grade limits. All key parameters - including on-resistance, leakage, and switching speed - are specified across this full range.
Does the MAX4541EUA support break-before-make switching?
No, the MAX4541EUA does not implement break-before-make functionality. As stated in the Features section and truth tables, this capability is explicitly reserved for the MAX4543 and MAX4544 variants. The MAX4541EUA contains two independent normally open SPST switches with no internal interlock - meaning both channels can be turned on simultaneously, but neither guarantees isolation during transition.
Can the MAX4541EUA operate from a +3.3V supply?
Yes, the MAX4541EUA fully supports +3.3V single-supply operation, as verified in the "Electrical Characteristics-Single +3.3V Supply" table. At V+ = +3.3V, it delivers 125Ω max on-resistance, 400ns max turn-on time, and maintains TTL/CMOS logic compatibility with input thresholds referenced to the 3.3V rail - making it suitable for modern low-voltage microcontroller interfaces.
What is the maximum analog signal voltage the MAX4541EUA can switch?
The MAX4541EUA supports analog signals from GND to V+, as defined in the "Analog Signal Range" specification. When powered from +5V, signals from 0V to +5V are fully supported with minimal RON variation. Exceeding V+ or dropping below GND risks forward-biasing internal ESD diodes; absolute maximum ratings limit analog pins to (V+ + 0.3V) and -0.3V minimum.
Is the MAX4541EUA pin-compatible with older Maxim analog switches?
Yes, the MAX4541EUA is pin-compatible with the MAX323, MAX324, and MAX325 as explicitly noted in the Features section. This allows drop-in replacement in existing designs using those legacy parts, provided the extended -40°C to +85°C temperature range and improved specifications (e.g., lower charge injection, tighter RON matching) are acceptable for the application.
