Product details
Overview
MAX4601CPE 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 reed relay replacement and automated test equipment where low distortion and high reliability are critical.
For engineers reviewing the MAX4601CPE datasheet, MAX4601CPE pinout, MAX4601CPE application, or MAX4601CPE equivalent, key selection criteria include guaranteed RON flatness (0.5Ω max), TTL/CMOS-compatible logic thresholds (+0.8V/+2.4V), ESD protection >2000V, and 16-pin Plastic DIP packaging for through-hole prototyping and industrial control boards.
Technical Context
The MAX4601CPE implements CMOS-based transmission-gate architecture with independent channel control, enabling true bidirectional analog signal switching across the full supply range. Its matched RON and flat on-resistance ensure minimal gain error and crosstalk in multiplexed sensor or audio signal paths.
All four switches share common analog supply pins (V+, V−, GND) and logic supply (VL), with digital inputs referenced to VL and compatible with +12V single-supply or ±15V dual-supply operation. The device guarantees performance over 0°C to +70°C and supports rail-to-rail input/output voltage swing without clipping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max - ensures <10mV drop at 4mA signal current, preserving accuracy in precision instrumentation |
| RON Match | 0.5Ω max - enables <0.2% gain matching across channels for multi-channel data acquisition |
| RON Flatness | 0.5Ω max over full signal range - maintains consistent attenuation across ±10V analog signals |
| Off-Leakage Current | 2.5nA max at +85°C - minimizes DC error in high-impedance sensor front-ends and sample-hold circuits |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - supports industrial 24V systems and legacy ±15V test equipment |
| Logic Thresholds | +0.8V low / +2.4V high - ensures reliable TTL/CMOS compatibility without level-shifting at +12V or ±15V supplies |
| ESD Protection | >2000V per Method 3015.7 - provides robust handling during board assembly and field service |
Pinout & Package
MAX4601CPE uses a 16-pin Plastic DIP package (0.3-inch width), suitable for through-hole mounting, manual prototyping, and legacy industrial PCBs. Pin spacing complies with standard 0.1-inch grid layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; active-low logic turns ON NC path (logic "0" = closed) |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - bidirectional signal interface points for each switch |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals - connected to COM when IN = 0V |
| 4 | V− | Negative analog supply - tied to GND for single-supply operation |
| 5 | GND | Digital/analog ground reference - must be low-impedance return path for leakage control |
| 12 | VL | Logic supply input - accepts 3V to 5V, independent of analog supply rails |
| 13 | V+ | Positive analog supply - defines upper rail for rail-to-rail signal handling |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Signal Handling | Supports analog signals from V− to V+ without clipping - essential for ±10V sensor interfaces and audio line-level routing |
| Guaranteed RON Match | 0.5Ω max mismatch between any two channels - enables accurate differential or ratiometric measurements |
| Low Charge Injection | 20pC typical - reduces voltage glitch in sample-and-hold and ADC input conditioning circuits |
| Fast Switching | 160ns turn-on / 170ns turn-off (typical at VCOM = 10V) - supports multiplexing up to ~3MHz without settling penalty |
| High Off-Isolation | −56dB at 1MHz - suppresses crosstalk between inactive channels in dense analog routing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4601CWE | Same electrical specs; 16-pin Wide SO package (surface-mount, 7.5mm width) | Better suited for high-density PCBs and automated assembly; no through-hole footprint | Select MAX4601CWE for volume production requiring SMT placement and thermal performance. |
| ADG441BRZ | Quad SPST NO switch (not NC); 4.5Ω RON max; operates up to +36V but lacks guaranteed RON match spec | Requires logic inversion for NC-equivalent behavior; higher RON increases signal loss in low-voltage systems | Choose ADG441BRZ only if normally open topology is acceptable and RON matching is non-critical. |
Compared with MAX4601CPE, MAX4601CWE offers identical functionality in surface-mount form for space-constrained designs, while ADG441BRZ provides an alternative vendor option with relaxed matching specs but different default state-making MAX4601CPE the preferred choice for NC-critical, precision-matched applications.

FAQ
What is the default switch state of MAX4601CPE?
The MAX4601CPE features four normally closed (NC) analog switches. When all digital inputs (IN1–IN4) are at logic low (≤0.8V), the COM-to-NC paths are closed. Applying logic high (≥2.4V) opens those paths. This behavior is confirmed in the truth table and functional diagrams of the MAX4601CPE datasheet and applies specifically to the CPE variant.
Can MAX4601CPE operate from a single +5V supply?
No - the MAX4601CPE requires a minimum analog supply of +4.5V, but its specified performance (including 2.5Ω RON and 0.5Ω match) is guaranteed only from +4.5V to +36V. At +5V, it functions but RON rises to ~3.5Ω (per typical curves), and leakage increases. For +5V systems, consider the MAX4617 or MAX4624 families instead of MAX4601CPE.
Does MAX4601CPE support bipolar signal switching?
Yes - the MAX4601CPE supports true bipolar analog signals from V− to V+. With dual supplies (e.g., ±15V), it handles ±10V signals rail-to-rail. When V− is tied to GND for single-supply use, it switches 0V to V+ signals. This capability is explicitly verified in the Electrical Characteristics tables for both dual- and single-supply conditions in the MAX4601CPE datasheet.
What is the maximum signal frequency supported by MAX4601CPE?
The MAX4601CPE maintains −2dB insertion loss up to >100MHz in 50Ω systems when ON, but off-isolation degrades above 300MHz. For reliable high-frequency switching (>5MHz), layout is critical - the MAX4601CPE datasheet recommends controlled-impedance routing and warns that characterization beyond 5MHz depends heavily on board design. For RF applications, Maxim recommends the MAX440/MAX442 series instead of MAX4601CPE.
Is MAX4601CPE pin-compatible with MAX4602CPE or MAX4603CPE?
Yes - all three variants (MAX4601CPE, MAX4602CPE, MAX4603CPE) share identical 16-pin Plastic DIP pinouts and package dimensions. Only the internal switch configuration differs: MAX4601CPE is quad NC, MAX4602CPE is quad NO, and MAX4603CPE is dual NC + dual NO. This allows direct substitution in the same footprint when logic polarity and default state are accounted for in firmware or external circuitry.
