Product details
Overview
MAX4601EAE from Maxim Integrated is a quad SPST analog switch with four normally closed (NC) channels, designed for rail-to-rail signal routing in precision analog systems. It delivers 2.5Ω max on-resistance, 0.5Ω max RON match between channels, and 2.5nA max off-leakage at +85°C, operating from single +4.5V to +36V or dual ±4.5V to ±20V supplies. It is used in automatic test equipment for reed relay replacement where low distortion and high reliability are critical.
For engineers reviewing the MAX4601EAE datasheet, MAX4601EAE pinout, MAX4601EAE application, or MAX4601EAE equivalent, key selection criteria include guaranteed RON flatness (0.5Ω max), TTL/CMOS-compatible logic thresholds (+0.8V/+2.4V), ESD protection >2000V, and -40°C to +85°C industrial temperature rating in 16-pin SSOP package.
Technical Context
The MAX4601EAE implements CMOS-based transmission-gate architecture with matched P- and N-channel devices per switch, enabling rail-to-rail analog signal handling across its full supply range. Its control logic accepts standard TTL/CMOS levels independent of supply voltage, with dedicated VL pin for logic-level translation.
Each NC switch connects COM to NC when IN = 0V and disconnects when IN = logic high, supporting fail-safe operation in safety-critical signal paths. The device guarantees monotonic RON flatness and channel-to-channel matching over temperature and signal voltage - critical for instrumentation multiplexing and audio routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max - ensures minimal signal attenuation and gain error in precision measurement paths |
| RON Match | 0.5Ω max - enables accurate differential signal switching without channel-induced offset |
| RON Flatness | 0.5Ω max over signal range - maintains consistent gain and linearity across full ±10V analog swing |
| Off-Leakage Current | 2.5nA max at +85°C - preserves high-impedance node integrity in sensor front-ends and sample-hold circuits |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports wide industrial and test-equipment power architectures |
| Logic Thresholds | +0.8V low / +2.4V high - ensures robust TTL/CMOS compatibility without level-shifting circuitry |
| ESD Protection | >2000V per Method 3015.7 - reduces board-level ESD hardening requirements in handling-sensitive environments |
Pinout & Package
MAX4601EAE is housed in a 16-pin SSOP (Shrink Small Outline Package) with 0.65mm lead pitch, optimized for high-density PCB layouts while maintaining thermal performance up to +85°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; active-low logic drives NC closure (IN = 0V → COM–NC path closed) |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - bidirectional signal ports connected to NC pins when enabled |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals - provide default continuity path in absence of logic drive |
| 4 | V− | Negative analog supply rail; tied to GND for single-supply operation |
| 5 | GND | Ground reference for logic and substrate; must be low-impedance return path |
| 12 | VL | Logic supply input - decouples logic threshold reference from analog rails for stable switching |
| 13 | V+ | Positive analog supply rail - sets upper bound of rail-to-rail signal range |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for full-scale data acquisition and audio routing |
| Guaranteed RON match | 0.5Ω max mismatch between any two switches - enables precise channel balancing in multi-path instrumentation |
| Low charge injection (20pC typ) | Minimizes voltage glitch on sampled nodes - critical for high-resolution ADC front-ends and sample-hold stability |
| Fast switching (160ns tON, 170ns tOFF) | Enables high-throughput multiplexing in automated test systems with sub-microsecond channel settling |
| High off-isolation (−56dB typ) | Suppresses crosstalk between inactive channels - preserves signal integrity in dense analog routing matrices |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4601EWE | Same electrical specs; packaged in 16-pin Wide SO (SOIC-W) instead of SSOP | Requires larger PCB footprint but offers easier hand-soldering and higher thermal mass | Select for prototyping or low-volume production where SSOP assembly infrastructure is unavailable |
| ADG1411BRUZ | Quad SPST, NC; 1.8Ω max RON, −40°C to +125°C, but requires separate logic supply and lacks VL pin | Better RON and extended temperature range, yet needs external level-shifting for mixed-voltage systems | Choose when lower on-resistance is prioritized and system supports dual logic/analog supply domains |
Compared with MAX4601EAE, MAX4601EWE offers identical functionality in a more manufacturable SOIC package, while ADG1411BRUZ trades integrated logic-level flexibility for lower RON and wider temperature tolerance - requiring careful evaluation of supply architecture and thermal environment.

FAQ
What is the maximum allowable supply voltage for MAX4601EAE?
The MAX4601EAE supports absolute maximum ratings of V+ to GND = −0.3V to +44V and V− to GND = +0.3V to −44V. For reliable operation, use within the recommended ranges: +4.5V to +36V single supply or ±4.5V to ±20V dual supply. Exceeding these limits risks permanent damage, as confirmed in the Absolute Maximum Ratings table of the MAX4601EAE datasheet.
Does MAX4601EAE support rail-to-rail analog signals with dual ±15V supplies?
Yes, MAX4601EAE fully supports rail-to-rail analog signal handling from V− to V+ under dual ±15V operation. The device maintains 2.5Ω max on-resistance and 0.5Ω max RON flatness across the full ±10V signal range, as verified in the Electrical Characteristics tables for dual-supply conditions in the MAX4601EAE datasheet.
How does the VL pin function in MAX4601EAE?
The VL pin on MAX4601EAE provides an independent logic supply reference, allowing TTL/CMOS-compatible input thresholds (+0.8V low, +2.4V high) regardless of analog supply voltage. This enables clean logic interfacing in mixed-voltage systems - for example, using 3.3V or 5V logic control with ±15V analog rails - without external level shifters.
Can MAX4601EAE replace mechanical relays in high-cycle-count test fixtures?
Yes, MAX4601EAE is explicitly qualified for reed relay replacement in automatic test equipment. With no moving parts, it supports unlimited switching cycles, eliminates contact bounce, and delivers 2.5nA max off-leakage at +85°C - ensuring long-term reliability in high-throughput test fixtures where mechanical relay wear would otherwise cause drift or failure.
What is the guaranteed RON match specification for MAX4601EAE across temperature?
MAX4601EAE guarantees ≤0.5Ω maximum on-resistance mismatch (∆RON) between any two channels over the full −40°C to +85°C operating temperature range. This parameter is tested and specified in the Electrical Characteristics table under "On-Resistance Match Between Channels (Note 4)" for both single- and dual-supply conditions in the MAX4601EAE datasheet.
