Product details
Overview
MAX4541EKA-T 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, 5pC max charge injection, and supports battery-powered systems requiring fast switching (tON = 35ns typ) and ultra-low power consumption (5µW).
For engineers reviewing the MAX4541EKA-T datasheet, MAX4541EKA-T pinout, MAX4541EKA-T application, or MAX4541EKA-T 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 rail-to-rail input capability across supply voltages.
Technical Context
The MAX4541EKA-T implements two independent SPST NO switches in a monolithic CMOS process, enabling bidirectional analog signal routing with minimal distortion. Its architecture ensures low leakage (<10nA at +85°C), flat on-resistance (6Ω max RON flatness), and high ESD robustness (>2000V per Method 3015.7).
It operates without external biasing, accepts logic inputs compatible with TTL or rail-to-rail levels depending on V+, and maintains stable RON over the full analog signal range (GND to V+). The device does not support break-before-make functionality-this feature applies only to MAX4543/MAX4544 variants.
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 level shifting |
| On-Resistance (RON) | 60Ω max at +5V - ensures minimal signal attenuation and voltage drop in precision signal paths |
| RON Matching | 2Ω max between channels - critical for matched gain/attenuation in differential or dual-path circuits |
| Charge Injection | 5pC max - reduces settling error and glitch energy in sample-and-hold and multiplexed ADC front-ends |
| Switching Speed | tON = 35ns typ, tOFF = 25ns typ at +5V - supports high-speed signal routing up to ~10MHz bandwidth |
| Leakage Current | 10nA max at +85°C - preserves accuracy in high-impedance sensor interfaces and battery-monitoring circuits |
| ESD Protection | >2000V per Method 3015.7 - provides robust handling margin during board assembly and field operation |
Pinout & Package
SOT23-8 package (top mark: AAAE), 1.50mm × 2.30mm body, 0.65mm pitch, exposed pad optional (not connected internally per datasheet).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | COM1 | Common terminal of first SPST switch - bidirectional analog path connection point |
| 2 | IN1 | Digital control input for first switch - active-high logic controls COM1–NO1 conduction |
| 3 | GND | Ground reference for analog and digital domains - must be low-impedance for noise immunity |
| 4 | NC2 | Not internally connected - no electrical function; leave unconnected or grounded per layout best practice |
| 5 | COM2 | Common terminal of second SPST switch - independent analog path, electrically isolated from COM1 |
| 6 | IN2 | Digital control input for second switch - decoupled logic control enables asynchronous channel operation |
| 7 | V+ | Positive supply input - powers both analog switch core and logic interface; absolute max +13V |
| 8 | NO1 | Normally open terminal of first switch - connects to COM1 only when IN1 = high |
Key Features
| Feature | Design Value |
|---|---|
| Low on-resistance flatness | 6Ω max variation across 0–V+ signal range - maintains consistent gain/attenuation in audio and sensor conditioning |
| TTL/CMOS logic compatibility | Guaranteed at +5V; rail-to-rail input support at other supplies - eliminates need for external level translators |
| Ultra-low power consumption | 5µW typical at +5V - extends battery life in portable medical, instrumentation, and IoT edge nodes |
| High off-isolation | -76dB at 1MHz - prevents crosstalk between active and inactive signal paths in multiplexed systems |
| Small footprint packaging | SOT23-8 (1.5mm × 2.3mm) - saves PCB area in space-constrained handheld and wearable designs |

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, same electrical specs, +85°C max operating temperature | Larger footprint; better thermal dissipation and hand-solderability | Select for prototyping, legacy board reuse, or higher-power thermal environments where SOT23-8 thermal limits (421mW) are marginal |
| ADG1419BRMZ | Single SPDT, 1.5Ω typical RON, ±15V dual-supply capable, 10ns switching | Higher performance but different topology (SPDT vs SPST); requires dual supply or level-shifting for single-supply use | Select only if SPDT functionality, lower RON, or wider voltage range is required - not a drop-in replacement |
Compared with MAX4541ESA, the MAX4541EKA-T offers identical analog performance in a 40% smaller footprint but reduced thermal mass; compared with ADG1419BRMZ, it provides SPST topology and single-supply simplicity at the cost of higher RON and slower switching - making it optimal for cost-sensitive, space-constrained industrial and portable designs.

FAQ
What is the operating temperature range of the MAX4541EKA-T?
The MAX4541EKA-T is rated for operation from -40°C to +85°C, qualifying it for industrial and extended-temperature embedded applications. This range is confirmed in the Ordering Information table, where "E" suffix denotes the -40°C to +85°C grade, and "KA" specifies the SOT23-8 package. The device undergoes 100% testing at +25°C and correlation-based guarantee across the full range.
Does the MAX4541EKA-T support break-before-make switching?
No, the MAX4541EKA-T does not support break-before-make (BBM) switching. BBM is explicitly specified only for the MAX4543 and MAX4544 variants in the Features section and Truth Tables. The MAX4541EKA-T is a dual SPST NO device with independent channel control - simultaneous turn-on of both switches is possible, and no internal timing delay enforces BBM behavior.
What is the maximum analog signal voltage range supported by the MAX4541EKA-T?
The MAX4541EKA-T supports analog signals from GND to V+ (0V to +12V max), as stated in the "Analog Signal Range" parameter and confirmed in Applications Information. This rail-to-rail capability holds across the full supply range (+2.7V to +12V) and is enabled by its CMOS switch architecture - no external clamping diodes are needed unless overvoltage protection beyond absolute maximum ratings is required.
Is the MAX4541EKA-T pin-compatible with older Maxim analog switches?
Yes, the MAX4541EKA-T is pin-compatible with the MAX323, MAX324, and MAX325 per the Features list. All share the same SOT23-8 pinout for dual SPST NO configuration (COM1/IN1/GND/NC2/COM2/IN2/V+/NO1). However, note that MAX323/MAX324/MAX325 operate only up to +6V and exhibit higher RON (100Ω typ), so electrical substitution requires verification of supply voltage and on-resistance requirements.
What is the meaning of the top-mark code "AAAE" on the MAX4541EKA-T package?
The top-mark "AAAE" uniquely identifies the MAX4541EKA-T variant per Maxim's ordering documentation: "AAAE" corresponds to the MAX4541EKA-T (SOT23-8, -40°C to +85°C), distinguishing it from MAX4542EKA-T (AAAF) and MAX4543EKA-T (AAAG). This marking enables visual traceability and counterfeit detection during incoming inspection and assembly.
