Product details
Overview
MAX4680EAE from Maxim Integrated is a dual SPST CMOS analog switch with two normally closed (NC) channels, designed for rail-to-rail signal routing in precision analog systems. It delivers 1.25Ω max on-resistance, 0.3Ω max RON 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 MAX4680EAE datasheet, MAX4680EAE pinout, MAX4680EAE application, or MAX4680EAE equivalent, this device is evaluated for high-voltage single- or dual-supply operation (+4.5V to +36V or ±4.5V to ±20V), TTL/CMOS-compatible logic control via dedicated VL pin, and guaranteed break-before-make timing only in the MAX4700 variant-not applicable to MAX4680EAE.
Technical Context
The MAX4680EAE implements fully independent dual NC switches with separate COM/NC paths per channel, each supporting continuous ±200mA analog current and rail-to-rail signal handling across its full supply range. Its on-resistance flatness is specified at ≤0.3Ω over the entire analog input range, ensuring minimal harmonic distortion in audio and instrumentation signal paths.
It features isolated logic supply (VL) pin enabling stable TTL/CMOS-level control regardless of analog supply voltage, and integrates >2kV ESD protection per Method 3015.7 on all pins. No internal break-before-make circuitry is present-this function is exclusive to the MAX4700 variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 1.25Ω max - ensures minimal voltage drop and power loss at 10mA signal current |
| RON Match | 0.3Ω max difference between channels - critical for matched gain/attenuation in differential or dual-path circuits |
| RON Flatness | 0.3Ω max variation over full signal range - preserves linearity in precision ADC/DAC interface applications |
| Off-Leakage Current | 5nA max at +85°C - enables high-impedance sample-and-hold hold times exceeding 10 seconds |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial sensor front-ends and automated test equipment rails |
| Logic Compatibility | TTL/CMOS inputs with dedicated VL pin - allows independent logic voltage (e.g., 3.3V or 5V) while analog supplies run at ±15V |
| ESD Protection | >2kV per Method 3015.7 - reduces need for external transient suppression in board-level ESD zones |
Pinout & Package
MAX4680EAE is housed in a 16-pin SSOP package (width = 4.4mm, body size 5.0mm × 6.2mm), RoHS-compliant and moisture-sensitive level 1 (MSL1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | N.C. | No internal connection; must be tied to GND or low-impedance node to maximize off-isolation |
| 2, 7 | GND | Analog and digital ground reference; shared return for V−, VL, and logic inputs |
| 4 | V− | Negative analog supply input; connect to GND for single-supply operation |
| 5 | GND | Primary ground pin - use as main system ground tie point |
| 9, 16 | NC1, NC2 | Normally closed analog terminals - conduct to COM when IN = logic low |
| 11, 14 | COM1, COM2 | Common analog ports - bidirectional signal path shared with NC1/NC2 |
| 12 | VL | Dedicated logic supply - sets input threshold (0.8V/2.4V) independently of analog rails |
| 13 | V+ | Positive analog supply - defines upper rail for rail-to-rail signal handling |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports input signals from V− to V+ without clipping - essential for ±10V sensor interfaces and DAC outputs |
| Guaranteed RON match (≤0.3Ω) | Enables precise channel balancing in dual-channel instrumentation amplifiers and multiplexed calibration paths |
| Low 5nA off-leakage at +85°C | Extends hold time in sample-and-hold circuits beyond 10 seconds with 10nF capacitors |
| Dedicated VL logic supply pin | Decouples control logic voltage from analog supply - simplifies mixed-voltage system design and improves noise immunity |
| 1.25Ω max on-resistance | Minimizes insertion loss and THD in audio routing and high-fidelity signal chains |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4690EAE | Dual NO configuration (open at logic low); identical RON, leakage, and supply specs | Suitable where default-open behavior is required (e.g., safety-critical disconnect on power loss) | Select MAX4690EAE when fail-safe open state is needed; MAX4680EAE remains preferred for default-closed paths. |
| ADG1419BRUZ | Single-supply only (±15V max), 1.3Ω RON, no dedicated VL pin - logic thresholds track VDD | Limited to systems with unified analog/logic voltage domains; lacks independent logic supply flexibility | Choose ADG1419BRUZ only if VL decoupling is unnecessary and dual-supply operation is not required. |
Compared with MAX4680EAE, MAX4690EAE offers functional symmetry with inverted logic sense but identical analog performance, while ADG1419BRUZ trades supply flexibility and logic independence for slightly higher RON and no VL pin - making MAX4680EAE optimal for mixed-rail industrial signal routing.

FAQ
What is the maximum allowable voltage difference between V+ and V− for MAX4680EAE?
The MAX4680EAE supports a maximum V+ to V− differential of +44V, as specified in Absolute Maximum Ratings. This allows operation with ±20V dual supplies (40V differential) or +36V/–4.5V configurations (40.5V differential), provided neither supply exceeds its individual rating relative to GND. Exceeding 44V risks permanent damage.
Does MAX4680EAE support break-before-make switching?
No, MAX4680EAE does not feature break-before-make functionality. That capability is exclusive to the MAX4700 variant, which guarantees a minimum 5ns break interval. MAX4680EAE implements simple NC switching with no intentional dead-time - simultaneous conduction during transition is possible.
Can MAX4680EAE operate with a 3.3V logic supply on the VL pin while using ±15V analog supplies?
Yes, MAX4680EAE explicitly supports independent logic supply voltages via the VL pin. With VL = 3.3V, the device accepts standard 3.3V TTL/CMOS logic levels (0.8V low, 2.4V high) while operating from ±15V analog rails - enabling seamless interfacing with modern low-voltage microcontrollers in high-voltage analog systems.
What is the thermal performance of MAX4680EAE in SSOP package at +85°C ambient?
In its 16-pin SSOP package, MAX4680EAE has a thermal resistance θJA of 140°C/W. At +85°C ambient and 571mW max power dissipation (derated above +70°C), junction temperature remains within safe limits (<150°C) under typical load conditions. Derating begins at +70°C at 7.1mW/°C.
How does the NC configuration of MAX4680EAE affect system-level fault tolerance?
The normally closed topology of MAX4680EAE ensures signal continuity during power loss or logic failure - a key safety advantage in monitoring circuits and fail-safe sensor interfaces. Unlike NO variants, it defaults to conducting, eliminating single-point failure risk in critical signal paths where uninterrupted analog monitoring is required.
