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.
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.
Technical Context
The MAX4601EAE+ implements CMOS-based transmission-gate architecture with matched P- and N-channel devices per channel, enabling rail-to-rail analog signal handling across its full supply range. Its control logic uses fixed-threshold TTL/CMOS inputs referenced to VL, independent of analog supply rails.
Each NC switch exhibits monotonic RON variation ≤0.5Ω over the entire specified signal range (±10V with dual supplies, 0–10V with single +12V), and leakage currents are fully tested at maximum hot temperature (85°C) and correlated to room temperature performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 2.5Ω max - ensures minimal signal attenuation and voltage drop in low-level analog paths |
| RON match | 0.5Ω max - enables precise channel-to-channel gain matching in multiplexed instrumentation |
| RON flatness | 0.5Ω max - maintains consistent gain and linearity across full analog input range |
| Off-leakage current | 2.5nA max at +85°C - preserves accuracy in high-impedance sensor front-ends and sample-hold circuits |
| Supply range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - supports wide-range industrial and test-system power architectures |
| Logic thresholds | +0.8V low / +2.4V high - guarantees interoperability with standard TTL and CMOS controllers without level-shifting |
| ESD protection | >2000V per Method 3015.7 - reduces risk of field failure during handling and system integration |
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 and mechanical robustness in industrial environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; active-low logic turns ON NC switches (logic '0' = closed path) |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - connected to load or signal source in each SPST path |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals - conduct to COM when IN = 0; open when IN = 1 |
| 4 | V− | Negative analog supply rail - tied to GND for single-supply operation |
| 5 | GND | Digital ground reference - separate from analog supplies but must be low-impedance |
| 12 | VL | Logic supply input - accepts 3V to 5V, independent of V+ and V− rails |
| 13 | V+ | Positive analog supply rail - defines upper signal swing limit and powers internal switch circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for ±10V data acquisition and audio routing |
| Guaranteed RON flatness | 0.5Ω max variation across full signal range - eliminates gain nonlinearity in precision measurement paths |
| TTL/CMOS-compatible inputs | +0.8V/+2.4V thresholds with ±0.5µA input current - allows direct interface to microcontrollers and FPGAs |
| Low charge injection | 20pC typical - minimizes voltage glitch in sample-and-hold and switched-capacitor circuits |
| High off-isolation | -56dB at 1MHz - suppresses crosstalk between inactive channels in multi-channel multiplexers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1411BRUZ | Quad SPST NC; 1.8Ω max RON; ±15V dual supply only; no single-supply support | Requires dual-rail design; higher cost; superior RON but narrower supply flexibility | Prefer when lowest on-resistance is critical and dual ±15V is available |
| TS5A3157DCUR | Single SPST NC; 0.75Ω max RON; +1.65V to +5.5V supply only; not rated for industrial temp | Limited to low-voltage, single-supply consumer-grade use; no -40°C to +85°C rating | Only suitable for cost-sensitive, low-voltage, commercial-temp applications |
Compared with ADG1411BRUZ and TS5A3157DCUR, the MAX4601EAE+ uniquely balances wide supply range (+4.5V to +36V), industrial temperature rating, and guaranteed RON matching-making it the only option qualified for high-reliability, mixed-supply, and rail-to-rail analog routing in test and avionics systems.

FAQ
What is the maximum allowable supply voltage for MAX4601EAE+?
The MAX4601EAE+ supports absolute maximum analog supply ratings of V+ to GND = −0.3V to +44V and V− to GND = +0.3V to −44V. For reliable operation, the recommended supply range is +4.5V to +36V (single) or ±4.5V to ±20V (dual). Exceeding these ranges risks permanent damage, as confirmed in the Absolute Maximum Ratings table of the official datasheet.
Does MAX4601EAE+ support rail-to-rail analog signal switching?
Yes, the MAX4601EAE+ supports rail-to-rail analog signal handling - signals from V− to V+ pass through the NC switches with minimal distortion. This capability is explicitly guaranteed in the General Description and verified across all operating conditions, including worst-case RON flatness of 0.5Ω max over the full signal range.
What is the logic polarity of the control inputs on MAX4601EAE+?
The MAX4601EAE+ features active-low logic: a logic '0' (≤+0.8V) closes the NC switch (ON state), and a logic '1' (≥+2.4V) opens it (OFF state). This behavior is defined in the Pin Configurations diagram and Truth Tables section, and applies uniformly to all four INx pins (1, 8, 9, 16).
Can MAX4601EAE+ operate from a single +5V supply?
No - the minimum single-supply voltage for MAX4601EAE+ is +4.5V, and operation at exactly +5V is valid but requires verification of logic compatibility. With VL = +5V and V+ = +5V, the device functions, but RON increases (typical 4Ω at V+ = +5V), and signal range is limited to 0V to +5V. Full rail-to-rail performance requires ≥±5V dual or ≥+12V single supply.
Is MAX4601EAE+ pin-compatible with MAX4602EAE+ or MAX4603EAE+?
Yes - all three variants (MAX4601EAE+, MAX4602EAE+, MAX4603EAE+) share identical 16-pin SSOP packaging and pinout. The only functional difference is switch configuration: MAX4601EAE+ has four NC switches, MAX4602EAE+ has four NO switches, and MAX4603EAE+ has two NC + two NO. PCB layout and footprint are fully interchangeable.
