Product details
Overview
MAX4600CWE from Maxim Integrated is a dual SPST CMOS analog switch with one normally closed (NC) and one normally open (NO) channel, designed for rail-to-rail signal routing in precision analog systems. It delivers 1.25Ω max on-resistance, 0.25Ω max RON match between channels, and 0.3Ω max RON flatness over ±10V signal range, operating from +4.5V to +36V single supply or ±4.5V to ±20V dual supplies. It is used in automatic test equipment for reed relay replacement where low distortion and high reliability are critical.
For engineers reviewing the MAX4600CWE datasheet, MAX4600CWE pinout, MAX4600CWE application, or MAX4600CWE equivalent, key selection criteria include guaranteed RON matching, TTL/CMOS-compatible logic thresholds at +12V supply, ESD protection >2kV, and verified performance across -40°C to +85°C temperature range.
Technical Context
The MAX4600CWE implements complementary MOSFET-based SPST switching with independent control of NC and NO paths per channel. Its architecture ensures matched conduction characteristics and minimal signal-dependent resistance variation-critical for instrumentation multiplexing and audio signal routing.
It supports both single- and dual-supply operation with logic inputs referenced to VL (typically +5V), enabling interoperability with mixed-voltage digital controllers. Input voltage range extends from V− to V+, and all analog pins tolerate clamping diode-limited overvoltage conditions when external protection is added.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 1.25Ω max - ensures minimal insertion loss and voltage drop in signal paths up to ±10V. |
| RON Match | 0.25Ω max - guarantees consistent gain/attenuation across dual channels in differential or parallel configurations. |
| RON Flatness | 0.3Ω max over ±10V - preserves linearity and THD in audio and data acquisition applications. |
| Off-Leakage Current | 2.5nA max at +85°C - enables high-impedance sensor front-ends and precision measurement without signal corruption. |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial, test, and telecom power architectures. |
| Logic Thresholds | +0.8V / +2.4V - ensures direct interface with TTL/CMOS microcontrollers at +12V supply without level-shifting. |
| ESD Protection | >2kV per Method 3015.7 - provides robust handling during board assembly and field service. |
Pinout & Package
MAX4600CWE is housed in a 16-pin Wide SO (SOIC-W) package, 7.6mm × 10.3mm body size, with standard gull-wing lead form and 1.27mm pitch. Pin 1 is located at the top-left corner adjacent to the index notch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | No Connect (N.C.) | Not internally connected; recommended to tie to GND for improved off-isolation and noise immunity. |
| 2, 7 | COM1, COM2 | Common analog terminals - bidirectional signal ports shared between NC and NO paths per channel. |
| 4 | V− | Negative analog supply input - connect to GND for single-supply operation; supports dual-rail ±15V systems. |
| 5 | GND | Digital and analog ground reference - must be low-impedance and star-connected to minimize crosstalk. |
| 9, 16 | NC1, NC2 | Normally closed analog terminals - conduct to COM when IN = LOW; open when IN = HIGH. |
| 11, 14 | NO1, NO2 | Normally open analog terminals - conduct to COM when IN = HIGH; open when IN = LOW. |
| 12 | VL | Logic supply input - powers internal level-shifters; typically +5V, independent of analog supply rails. |
| 13 | V+ | Positive analog supply input - defines upper analog signal limit; supports up to +36V. |
| 1, 3, 6, 8, 10, 15 | IN1, IN2 | Digital control inputs - active-HIGH logic controls NO path; inverted logic controls NC path per truth table. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for full-scale sensor and DAC output routing. |
| Guaranteed RON match | 0.25Ω max difference between channels - enables precise differential signal switching in instrumentation amplifiers. |
| TTL/CMOS-compatible inputs | +0.8V / +2.4V thresholds at +12V supply - eliminates need for external level translators in PLC and ATE controller interfaces. |
| Low charge injection | 40pC typical - minimizes transient glitches in sample-and-hold and multiplexer-based data acquisition systems. |
| High off-isolation | -53dB typical at 1MHz - suppresses crosstalk between adjacent switched channels in dense PCB layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | Single-supply only (+5V to +36V); 0.9Ω max RON; no dual-supply support; higher 1.5nA leakage at +85°C. | Optimized for unipolar industrial sensors; lacks dual-rail flexibility for bipolar signal conditioning. | Select when system uses only positive supplies and requires lower RON, but verify logic compatibility with VL-referenced inputs. |
| TS5A23157DGSR | Lower voltage range (1.65V to 5.5V); 0.9Ω max RON; 100nA leakage at +85°C; no ESD rating specified. | Suitable for portable battery-powered devices; not rated for industrial or test equipment voltage/current stress. | Choose for cost-sensitive consumer electronics with 3.3V logic; avoid in ATE or telecom infrastructure due to voltage and reliability limits. |

FAQ
What is the maximum analog signal voltage range supported by the MAX4600CWE?
The MAX4600CWE supports rail-to-rail analog signals from V− to V+. When operated on ±15V dual supplies, this yields a full ±15V signal range; on +12V single supply (with V− = GND), it supports 0V to +12V. The device maintains 1.25Ω max on-resistance and 0.3Ω max RON flatness across ±10V within these rails, as confirmed in the Electrical Characteristics tables for both single- and dual-supply conditions. Exceeding absolute maximum ratings risks permanent damage.
Does the MAX4600CWE require external level-shifting when interfaced with a 3.3V microcontroller?
No, the MAX4600CWE does not require external level-shifting when driven by a 3.3V microcontroller. Its logic inputs have guaranteed TTL/CMOS-compatible thresholds of +0.8V (VIL) and +2.4V (VIH) when VL = +5V, and 3.3V logic outputs comfortably exceed VIH. The VL pin must be supplied with +5V (not tied to 3.3V), enabling clean recognition of 3.3V HIGH/LOW states without translation circuitry - a key design advantage confirmed in the Truth Tables and Logic Input specifications.
How is the normally closed (NC) and normally open (NO) behavior implemented in the MAX4600CWE?
The MAX4600CWE implements one NC and one NO switch per channel using complementary MOSFET topologies controlled by the same INx input. When INx = LOW, the NC path conducts (COMx ↔ NCx) and the NO path is open; when INx = HIGH, the NO path conducts (COMx ↔ NOx) and the NC path opens. This behavior is explicitly defined in the functional diagrams and truth tables for MAX4600, and differs from MAX4580 (dual NC) and MAX4590 (dual NO). Pin 9 is NC1, pin 16 is NC2, pin 11 is NO1, and pin 14 is NO2 - all verified in the Pin Description section.
What thermal derating applies to the MAX4600CWE in its Wide SO package?
The MAX4600CWE in 16-pin Wide SO package has a continuous power dissipation rating of 762mW at +70°C ambient, with a derating factor of 9.52mW/°C above that temperature. This means at +85°C ambient, allowable power drops to 762mW − (15°C × 9.52mW/°C) = 619mW. This value is explicitly listed in the Absolute Maximum Ratings table and correlates with the package's thermal resistance (θJA ≈ 105°C/W). Designers must calculate worst-case I²R losses (e.g., 200mA through 1.25Ω yields 50mW per channel) to ensure safe operation under full load and elevated temperature.
Can the MAX4600CWE be used in a single-supply configuration with V− left unconnected?
No, V− must not be left unconnected in single-supply operation. Per the Absolute Maximum Ratings and Applications Information sections, V− must be tied to GND when using a single positive supply (e.g., +12V at V+). Leaving V− floating violates the required bias condition for internal FET operation and may cause latch-up or undefined switching behavior. The datasheet explicitly states "Connect to GND for single-supply operation" in the Pin Description for pin 4 (V−), and Figure 1 shows V− grounded in the single-supply overvoltage protection schematic. Failure to ground V− invalidates all published electrical characteristics.
