Product details
Overview
MAX4600CPE 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 2.5nA max off-leakage at +85°C, enabling low-distortion switching in automatic test equipment and communication interfaces.
For engineers reviewing the MAX4600CPE datasheet, MAX4600CPE pinout, MAX4600CPE application, or MAX4600CPE equivalent, key selection criteria include single/dual supply operation (+4.5V to +36V or ±4.5V to ±20V), TTL/CMOS-compatible logic thresholds, guaranteed RON flatness (0.3Ω max), ESD protection (>2kV), and 16-pin plastic DIP package compatibility.
Technical Context
The MAX4600CPE implements complementary MOSFET-based SPST switching with independent control of NC and NO paths via separate digital inputs (IN1, IN2). Its architecture supports bidirectional rail-to-rail analog signals up to ±10V with minimal distortion, leveraging matched P/N channel pairs to achieve tight RON tracking and flatness across the signal range.
Logic interface uses fixed +0.8V/+2.4V thresholds referenced to GND, ensuring interoperability with TTL/CMOS drivers under +12V single-supply or ±15V dual-supply conditions. Internal protection diodes clamp input overvoltage, while charge injection (40pC typ) and crosstalk (–65dB) are characterized for high-fidelity signal integrity in multiplexed measurement paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 1.25Ω maximum - ensures minimal voltage drop and power loss in signal paths carrying up to ±200mA continuous current |
| RON Match | 0.25Ω maximum difference between channels - critical for matched gain/attenuation in differential or dual-path circuits |
| RON Flatness | 0.3Ω maximum variation over signal range - preserves linearity for audio, sensor, and instrumentation signals |
| Off-Leakage Current | 2.5nA maximum at +85°C - maintains high impedance isolation for sensitive high-impedance nodes |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial, test, and telecom voltage rails without level-shifting |
| Logic Thresholds | +0.8V low / +2.4V high - guarantees direct interface with standard TTL/CMOS outputs at +12V or ±15V supplies |
| ESD Protection | >2kV per Method 3015.7 - enhances robustness in handling and board-level transient environments |
Pinout & Package
MAX4600CPE is housed in a 16-pin plastic DIP package (0.300" wide), compatible with through-hole PCB assembly and socketing for prototyping and test fixtures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | No-connect (N.C.) | Not internally connected; tie to GND or low-impedance node to improve off-isolation and reduce noise coupling |
| 2, 7 | COM1, COM2 | Common analog terminals - bidirectional signal ports shared between NC and NO paths per channel |
| 4 | V− | Negative analog supply - connect to GND for single-supply operation; supports dual-rail biasing down to −20V |
| 5 | GND | Ground reference - serves as return path for analog, digital, and logic supplies; requires low-impedance layout |
| 9, 16 | NC1, NC2 | Normally closed analog terminals - conduct to COM when IN = low; open when IN = high |
| 11, 14 | COM1, COM2 | Common analog terminals - repeated for clarity; same pins as row 2 |
| 12 | VL | Logic supply input - accepts +2.7V to +5.5V to set logic threshold reference independently of analog rails |
| 13 | V+ | Positive analog supply - supports up to +36V; defines upper rail for rail-to-rail signal handling |
| 1, 3, 6, 8, 10, 15 | N.C. | Unused pins - must not float; grounding minimizes capacitive coupling and improves EMI performance |
| IN1, IN2 (pins unspecified in DIP pinout but functionally assigned) | Digital control inputs | Active-high logic inputs controlling switch state; IN1 controls COM1/NC1/NO1, IN2 controls COM2/NC2/NO2 |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - enables full dynamic range use in data acquisition and signal conditioning |
| Guaranteed RON match | ≤0.25Ω channel-to-channel mismatch - eliminates gain error in dual-channel instrumentation amplifiers or balanced modulators |
| Low charge injection (40pC typ) | Minimizes voltage glitch on high-impedance nodes during switching - critical for sample-and-hold and precision ADC front-ends |
| TTL/CMOS-compatible inputs | Fixed +0.8V/+2.4V thresholds - eliminates need for external level shifters when interfacing with microcontrollers or FPGAs |
| Single/dual supply flexibility | Operates from +4.5V to +36V or ±4.5V to ±20V - simplifies power architecture in mixed-signal systems with diverse voltage domains |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | 1.3Ω RON, ±15V dual-supply only, 16-TSSOP package | Lacks single-supply support; higher RON flatness (0.5Ω) | Prefer for high-voltage dual-rail systems where TSSOP footprint is acceptable |

FAQ
What is the operating temperature range for the MAX4600CPE?
The MAX4600CPE is specified for operation from 0°C to +70°C. This commercial-grade temperature range is validated across all electrical parameters including on-resistance, leakage current, and switching times. The 'C' suffix in MAX4600CPE explicitly denotes the 0°C to +70°C grade, distinguishing it from the extended −40°C to +85°C 'E' grade variants like MAX4600EPE. Thermal derating is not required within this range.
Does the MAX4600CPE support single-supply operation?
Yes, the MAX4600CPE supports single-supply operation from +4.5V to +36V with V− connected to GND. In this configuration, the device maintains rail-to-rail signal handling from GND to V+, full TTL/CMOS logic compatibility using the VL pin, and all specified performance including 1.25Ω max RON and 2.5nA max off-leakage at +85°C. No external components are needed to enable single-supply mode.
How is the logic control configured for the two switches in the MAX4600CPE?
The MAX4600CPE features independent digital control: IN1 (pin assignment per package variant) controls the first switch (COM1 ↔ NC1/NO1), and IN2 controls the second (COM2 ↔ NC2/NO2). For the 16-pin DIP package, IN1 and IN2 are assigned to pins 1 and 15 respectively (per functional diagram and truth table). Each input uses +0.8V/+2.4V thresholds, with low = NC closed/NO open, high = NC open/NO closed - matching the MAX4600's mixed NC/NO topology.
What package type is used for the MAX4600CPE?
The MAX4600CPE uses a 16-pin plastic DIP (dual in-line package) with 0.300" body width. This through-hole package has 0.100" lead pitch and is compatible with standard DIP sockets and wave soldering processes. Pin 1 is located at the left end of the top row (notch side up), and the package outline conforms to JEDEC MS-001, enabling drop-in replacement in legacy designs originally using similar DIP analog switches.
Can the MAX4600CPE handle bipolar analog signals?
Yes, the MAX4600CPE handles bipolar analog signals when operated from dual supplies (±4.5V to ±20V). With V+ = +15V and V− = −15V, it supports rail-to-rail input/output signals from −15V to +15V. Internal protection diodes clamp signals exceeding the supply rails, and the device maintains 1.25Ω max RON and 0.25Ω max RON match across the full bipolar range - making it suitable for AC-coupled audio, op-amp level-shifting, and bipolar data acquisition front-ends.
