Product details
Overview
MAX4602CWE+T from Maxim Integrated is a quad single-pole single-throw (SPST) normally open (NO) analog switch IC with 2.5Ω maximum on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail signal handling up to ±10V. It features 0.5Ω max RON matching between channels, 0.4Ω typical RON flatness, and 2.5nA max off-leakage at +85°C - ideal for precision reed relay replacement in automated test equipment.
For engineers reviewing the MAX4602CWE+T datasheet, MAX4602CWE+T pinout, MAX4602CWE+T application, or MAX4602CWE+T equivalent, key selection criteria include guaranteed RON match across all four switches, TTL/CMOS-compatible logic thresholds (0.8V/2.4V), low charge injection (20pC), and wide supply flexibility enabling use in industrial control, audio routing, and avionics signal switching.
Technical Context
The MAX4602CWE+T implements four independent CMOS SPST NO switches with fully differential analog path architecture, supporting bidirectional rail-to-rail signal conduction from V− to V+. Its control logic uses buffered digital inputs referenced to VL (logic supply), ensuring robust noise immunity and compatibility with both +12V single-supply and ±15V dual-supply systems.
Each switch exhibits monotonic RON variation over temperature and signal voltage, with flatness specified to 0.5Ω max across −10V to +10V analog range. Off-isolation exceeds −56dB at 1MHz, and crosstalk remains below −60dB between any two channels - critical for high-fidelity multiplexing in communication and measurement systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max - ensures minimal signal attenuation and voltage drop in precision analog paths |
| RON Match | 0.5Ω max - guarantees consistent gain/attenuation across all four switched channels |
| RON Flatness | 0.5Ω max over ±10V - maintains linearity for audio and sensor signals without distortion |
| Off-Leakage Current | 2.5nA max at +85°C - preserves accuracy in high-impedance sensor front-ends |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - supports legacy industrial and modern mixed-voltage systems |
| Logic Thresholds | 0.8V low / 2.4V high - direct interface with TTL and CMOS controllers without level-shifting |
| Charge Injection | 20pC typical - minimizes transient glitches during switching in sample-and-hold circuits |
Pinout & Package
MAX4602CWE+T is housed in a 16-pin Wide SO (SOIC-W) package with 0.300-inch body width and standard 1.27mm pitch. Pin 1 is located at the top-left corner with notch or dot marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs for each of the four NO switches; active-high logic |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - bidirectional signal path entry points |
| 3, 6, 11, 14 | NO1–NO4 | Normally open analog outputs - connect to COM only when IN = high |
| 4 | V− | Negative analog supply rail; tied to GND for single-supply operation |
| 5 | GND | Digital/analog ground reference for logic and substrate bias |
| 12 | VL | Logic supply input - decouples control logic from analog rails for noise isolation |
| 13 | V+ | Positive analog supply rail - sets upper limit of rail-to-rail signal range |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Signal Handling | Supports analog signals from V− to V+ (e.g., ±10V or 0V to +12V), eliminating clipping in wide-dynamic-range applications |
| Guaranteed RON Matching | ≤0.5Ω difference between any two switches - enables precise channel-to-channel tracking in instrumentation multiplexers |
| TTL/CMOS-Compatible Inputs | 0.8V/2.4V thresholds ensure reliable switching with microcontrollers and FPGAs operating at +5V or +3.3V logic levels |
| ESD Protection | >2000V per Method 3015.7 - enhances robustness in manufacturing and field environments without external protection |
| Low Charge Injection | 20pC typical - reduces settling error in precision data acquisition and sampling circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1412BRUZ | Quad SPST NO, 1.8Ω max RON, ±15V supply, but requires VL = V+ and lacks separate logic supply pin | Better RON but no VL isolation - less suitable for mixed-signal noise-sensitive designs | Prefer MAX4602CWE+T when logic/analog domain separation is required |
| TS5A3157DCKR | Single SPST NO, 0.75Ω max RON, +1.65V to +5.5V only - not pin-compatible or functionally equivalent | Limited to low-voltage portable audio; cannot replace MAX4602CWE+T in industrial/high-voltage systems | Only viable for cost-sensitive, low-voltage consumer audio where quad integration is unnecessary |
Compared with ADG1412BRUZ and TS5A3157DCKR, the MAX4602CWE+T uniquely combines quad integration, wide supply range (±20V), dedicated VL pin for noise isolation, and guaranteed RON matching - making it the only drop-in solution for legacy ATE and avionics upgrades requiring reliability and signal integrity.

FAQ
What is the maximum supply voltage rating for MAX4602CWE+T?
The MAX4602CWE+T supports absolute maximum analog supply ratings of V+ to GND = −0.3V to +44V and V− to GND = +0.3V to −44V. For continuous operation, the recommended dual-supply range is ±4.5V to ±20V, and the single-supply range is +4.5V to +36V. Exceeding these limits risks permanent damage, as confirmed in the Absolute Maximum Ratings table of the official datasheet.
Does MAX4602CWE+T support rail-to-rail analog signal switching?
Yes, the MAX4602CWE+T supports true rail-to-rail analog signal conduction - meaning signals from V− to V+ (e.g., −15V to +15V or 0V to +12V) can pass through the switch with full fidelity. This is explicitly stated in the General Description and verified by the Input Voltage Range specification (VCOM_, VNO_, VNC_ = V− to V+).
What is the logic supply voltage (VL) requirement for MAX4602CWE+T?
The MAX4602CWE+T requires a dedicated logic supply voltage (VL) pin, which must be connected to a stable +5V source per the datasheet's Electrical Characteristics tables. VL powers the internal logic circuitry and is independent of V+ and V−, enabling noise isolation between control and analog domains - a key differentiator from many competing analog switches.
Can MAX4602CWE+T be used with a single +12V supply?
Yes, the MAX4602CWE+T operates reliably with a single +12V supply: connect V+ = +12V, V− = GND, and VL = +5V. The Electrical Characteristics table for "Single +12V Supply" confirms RON = 4Ω max, tON/tOFF = 160/170ns, and leakage specs remain valid - making it suitable for industrial PLC I/O modules and embedded control systems.
Is MAX4602CWE+T pin-compatible with other devices in the MAX460x family?
Yes, the MAX4602CWE+T shares identical pinout and package (16-pin Wide SO) with MAX4601CWE+T and MAX4603CWE+T. Only the switch configuration differs: MAX4601 is quad NC, MAX4602 is quad NO, and MAX4603 is dual NC/dual NO. This allows board-level reuse across designs requiring different default states without layout changes.
