Product details
Overview
MAX4541EKA 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 MAX4541EKA datasheet, MAX4541EKA pinout, MAX4541EKA application, or MAX4541EKA equivalent, key selection criteria include guaranteed break-before-make timing (not applicable), SOT23-8 package compatibility, -40°C to +85°C industrial temperature range, and TTL/CMOS logic interface with <5µW quiescent power consumption.
Technical Context
The MAX4541EKA implements two independent SPST switches with bidirectional analog signal paths, each controlled by dedicated CMOS/TTL-compatible digital inputs (IN1, IN2). Its channel architecture supports rail-to-rail analog signals from GND to V+, with on-resistance flatness of ≤6Ω over the full signal range.
It features internal ESD protection (>2000V per Method 3015.7), low leakage (≤10nA at +85°C), and fast switching (tON = 35ns typ, tOFF = 25ns typ at +5V), optimized for sample-and-hold circuits and multiplexed sensor interfaces where signal integrity and power efficiency are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.7V to +12V single supply - enables direct integration with 3.3V and 5V systems without level-shifting. |
| On-Resistance (RON) | 60Ω max at +5V - ensures minimal signal attenuation and gain error in precision analog paths. |
| RON Matching | 2Ω max between channels - critical for matched gain/phase in differential or dual-channel signal chains. |
| Charge Injection | 5pC max - reduces settling error and pedestal distortion in sampling circuits and ADC front-ends. |
| Leakage Current | 10nA max at +85°C - preserves accuracy in high-impedance sensor interfaces and battery-monitoring applications. |
| Switching Speed | tON = 35ns, tOFF = 25ns (typ, +5V) - supports >10MHz multiplexing rates in data acquisition systems. |
| ESD Protection | >2000V per Method 3015.7 - provides robust handling during board assembly and field operation. |
Pinout & Package
SOT23-8 package (8-pin, surface-mount, exposed pad optional per variant; MAX4541EKA uses standard SOT23-8 without EP). Pin pitch: 0.65mm; body size: 2.30mm × 1.70mm × 0.80mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (COM1) | Analog common terminal, Channel 1 | Bidirectional signal path hub - connects to NO1 when IN1 = high; must remain within GND–V+ range. |
| 2 (IN1) | Digital control input, Channel 1 | TTL/CMOS-compatible logic input - drives internal switch gate; threshold defined by V+ (e.g., VINH ≥ 2.4V at +5V). |
| 3 (GND) | Ground reference | Primary return path for analog and digital currents; decoupling capacitor required near pin. |
| 4 (NC2) | No-connect terminal | Internally unconnected - must be left floating or tied to GND per layout best practice; no electrical function. |
| 5 (COM2) | Analog common terminal, Channel 2 | Independent bidirectional node for second channel - isolated from COM1 except through external circuitry. |
| 6 (IN2) | Digital control input, Channel 2 | Independent logic control - allows asynchronous switching of Channel 2 without affecting Channel 1. |
| 7 (V+) | Positive supply voltage | Single power rail for analog and digital sections - must be stable and bypassed with 0.1µF ceramic capacitor. |
| 8 (NO1) | Normally open analog terminal, Channel 1 | Closed only when IN1 = high - forms complete path with COM1; bidirectional signal routing capability. |
Key Features
| Feature | Design Value |
|---|---|
| Low on-resistance flatness | ≤6Ω variation across 0–V+ signal range - maintains consistent gain and linearity in variable-amplitude signals. |
| Ultra-low power consumption | <5µW typical - extends battery life in portable test equipment and wearable health monitors. |
| Guaranteed channel matching | 2Ω max RON mismatch - eliminates calibration drift in dual-channel instrumentation amplifiers. |
| TTL/CMOS logic compatibility | Operates with 0V/3.3V or 0V/5V logic levels - simplifies interface with microcontrollers and FPGAs without external translators. |
| High ESD immunity | >2000V HBM - protects against electrostatic discharge during handling and system integration. |

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 | SO-8 package (5.0mm × 4.0mm), same electrical specs, +85°C max operating temperature | Preferred for through-hole prototyping or legacy PCBs requiring SO footprint | Select when board space permits larger package and hand-soldering is required. |
| ADG702BRMZ | 2.5V–5.5V supply only; 4Ω max RON; 1.8ns switching; different pinout (no NC pins) | Better performance in 3.3V-only systems but incompatible with 12V operation or SOT23-8 layout | Choose only if supply is strictly ≤5.5V and faster switching is mandatory. |
Compared with MAX4541ESA, the MAX4541EKA offers identical functionality in a space-constrained SOT23-8 package ideal for portable designs, while ADG702BRMZ trades wide supply range and pin compatibility for lower RON and speed - requiring PCB redesign and voltage constraint validation.

FAQ
What is the maximum supply voltage rating for the MAX4541EKA?
The MAX4541EKA has an absolute maximum supply voltage (V+) of +13V, with recommended operating range from +2.7V to +12V. Exceeding +13V risks permanent damage per Absolute Maximum Ratings. The device is fully specified at +5V and +3.3V supplies, delivering 60Ω max RON and 5pC max charge injection within this range. Always observe proper power-supply sequencing - apply V+ before analog or logic signals.
Does the MAX4541EKA support break-before-make switching?
No, the MAX4541EKA does not implement break-before-make functionality. That feature is explicitly reserved for the MAX4543 and MAX4544 variants per the datasheet's "Features" section. The MAX4541EKA contains two independent normally open (NO) SPST switches with no internal timing coordination between channels - each switch operates asynchronously based solely on its respective IN1 or IN2 control signal.
What is the thermal performance of the MAX4541EKA in SOT23-8 package?
The MAX4541EKA in SOT23-8 has a power dissipation limit of 421mW at +70°C, derating linearly by 5.3mW/°C above that temperature. At maximum rated junction temperature (+125°C), usable power drops to ~135mW. This thermal profile supports continuous operation in industrial environments (-40°C to +85°C ambient) when paired with appropriate PCB copper area and 0.1µF local bypass capacitance at V+.
Can the MAX4541EKA handle analog signals beyond the supply rails?
No - the MAX4541EKA's analog signal range is strictly limited to GND ≤ VANALOG ≤ V+. Signals exceeding these bounds risk forward-biasing internal ESD diodes, causing excessive current flow and potential damage. The datasheet specifies absolute maximum ratings of -0.3V to (V+ + 0.3V) on COM/NO/NC pins, but functional operation requires staying within the GND–V+ window to ensure specified RON, leakage, and switching behavior.
Is the MAX4541EKA pin-compatible with older Maxim analog switches?
Yes, the MAX4541EKA is pin-compatible with the MAX323, MAX324, and MAX325 per the datasheet's "Features" list. All share identical SOT23-8 pinout: COM1/IN1/GND/NC2/COM2/IN2/V+/NO1. This allows drop-in replacement in existing designs using those legacy parts, provided the wider supply range (+2.7V–+12V vs. MAX32x's +5V–+15V) and improved specs (e.g., 5pC vs. 10pC charge injection) are verified for the target application.
