Product details
Overview
MAX4662CAE+ from Maxim Integrated is a quad single-pole single-throw (SPST) analog switch with normally open (NO) configuration, designed for rail-to-rail signal routing in precision analog systems. It delivers 2.5Ω max on-resistance, 0.4Ω typical on-resistance match between channels, and 5nA max off-leakage at +85°C, enabling low-distortion switching in data acquisition and test equipment.
For engineers reviewing the MAX4662CAE+ datasheet, MAX4662CAE+ pinout, MAX4662CAE+ application, or MAX4662CAE+ equivalent, this device is evaluated for high-voltage analog multiplexing, reed relay replacement, and audio-signal routing where low RON flatness and TTL/CMOS-compatible control are critical selection criteria.
Technical Context
The MAX4662CAE+ operates from a single +4.5V to +36V supply or dual ±4.5V to ±20V supplies, with a separate VL pin ensuring logic-level compatibility across the full analog supply range. Its CMOS architecture supports rail-to-rail analog signal handling up to ±10V with minimal distortion.
Each of the four independent NO switches features guaranteed RON matching ≤0.5Ω and RON flatness ≤0.7Ω over the specified signal range, verified per Notes 3–5 in the datasheet. Switching dynamics include 400ns typical turn-on time and 350ns typical turn-off time at VCOM = 10V under single-supply conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max - ensures minimal voltage drop and signal attenuation in precision analog paths |
| RON Match Between Channels | 0.5Ω max - enables matched gain/attenuation in multi-channel instrumentation and ADC front-ends |
| RON Flatness | 0.7Ω max - maintains consistent channel performance across full ±10V input range |
| Off-Leakage Current | 5nA max at +85°C - preserves accuracy in high-impedance sensor interfaces and sample-and-hold circuits |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial, avionics, and wide-range test equipment rails |
| Logic Compatibility | TTL/CMOS inputs with VL pin - decouples logic threshold from analog supply, simplifying mixed-voltage system design |
| ESD Protection | >2kV per Method 3015.7 - enhances robustness in handling and board-level ESD events |
Pinout & Package
MAX4662CAE+ is housed in a 16-pin SSOP (Shrink Small Outline Package) with 0.65mm lead pitch, optimized for space-constrained industrial and test equipment PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; active-high logic turns corresponding NO switch ON |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - connect to signal source or load in SPST topology |
| 3, 6, 11, 14 | NO1–NO4 | Normally open analog switch outputs - conduct only when respective IN_ = HIGH |
| 4 | V− | Negative analog supply rail; tied to GND for single-supply operation |
| 5 | GND | Ground reference for logic and substrate; requires low-impedance connection |
| 12 | VL | Independent logic supply input - sets input threshold independently of V+ and V− |
| 13 | V+ | Positive analog supply rail - defines upper limit of rail-to-rail signal range |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports continuous DC to ±10V signals without clipping or distortion, critical for full-scale sensor and DAC interfaces |
| Guaranteed RON match ≤0.5Ω | Enables precise channel-to-channel tracking in multi-input multiplexers and programmable-gain amplifier paths |
| Low 5nA off-leakage at +85°C | Maintains integrity of high-impedance nodes in sample-and-hold and battery-powered data loggers |
| Break-before-make not applicable | MAX4662CAE+ is NO-only; no internal break-before-make timing - avoids unintended shorting in shared-bus configurations |
| Separate VL logic supply pin | Allows interface with 3.3V or 5V microcontrollers while operating analog rails up to ±20V, eliminating level-shifters |

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, but only rated for +15V single supply (vs. +36V for MAX4662CAE+) | Better RON for low-voltage audio, but unsuitable for ±15V industrial signal chains | Select ADG1412BRUZ only if supply stays ≤+15V and lower RON outweighs voltage range loss |
| TS5A3157DCUR | Single-channel SPST NO, 0.75Ω max RON, 5V-only supply, SC70-6 package | Higher density per switch but requires 4x ICs and layout area vs. integrated quad in MAX4662CAE+ | Choose TS5A3157DCUR for ultra-low RON in space-limited 5V-only designs; avoid for multi-channel consolidation |
Compared with ADG1412BRUZ and TS5A3157DCUR, MAX4662CAE+ uniquely balances wide supply range (+4.5V to +36V), quad integration, and guaranteed RON matching - making it optimal for industrial multiplexers and high-voltage test systems where channel consistency and supply flexibility are non-negotiable.

FAQ
What is the maximum analog signal voltage range supported by the MAX4662CAE+?
The MAX4662CAE+ supports rail-to-rail analog signals up to ±10V when operated from dual ±15V supplies, or 0V to +10V with +12V single supply. Absolute maximum ratings allow V+ to +36V and V− to −44V, but signal swing is constrained by supply rails - e.g., with V+ = +24V and V− = GND, the usable analog range is 0V to +24V, though guaranteed performance is specified to ±10V.
Does the MAX4662CAE+ require external protection diodes for overvoltage conditions?
The MAX4662CAE+ includes internal protection diodes, but Maxim recommends external series diodes (e.g., D1/D2 in Figure 1 of the datasheet) if supply sequencing cannot guarantee V+ powers first, then V−, then logic inputs. This prevents latch-up during hot insertion or uncontrolled power-up, especially in systems with mismatched supply ramp rates.
Can the MAX4662CAE+ be used in a dual-supply configuration with asymmetric rails, such as +12V and −5V?
Yes - the MAX4662CAE+ supports asymmetric dual supplies as long as V+ to V− differential remains ≤44V and each rail stays within absolute maximum ratings (V+ ≥ −0.3V, V− ≤ +0.3V relative to GND). For +12V/−5V operation, the analog signal range becomes −5V to +12V, and RON performance remains within spec per the Electrical Characteristics table.
What is the guaranteed break-before-make behavior of the MAX4662CAE+?
The MAX4662CAE+ has no break-before-make functionality - it is a purely normally open (NO) switch with no guaranteed timing separation between channel turn-off and turn-on. Break-before-make is exclusive to the MAX4663 variant; using MAX4662CAE+ in shared-bus applications requires external timing control to prevent momentary shorts.
How does the VL pin affect logic interface compatibility in the MAX4662CAE+?
The VL pin sets the logic threshold independently of V+ and V−, allowing TTL/CMOS-compatible inputs (VIN_H = 2.4V min, VIN_L = 0.8V max) even when analog supplies operate at +30V or ±20V. This eliminates level-shifting circuitry when interfacing with 3.3V or 5V microcontrollers in high-voltage systems - a key advantage over fixed-threshold analog switches.
