Product details
Overview
MAX4680EAE+ from Maxim Integrated is a dual SPST CMOS analog switch with two normally closed (NC) channels, designed for precision signal routing in rail-to-rail analog paths. 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, key selection criteria include guaranteed NC configuration, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, TTL/CMOS-compatible control inputs, and break-before-make absence (distinguishing it from MAX4700).
Technical Context
The MAX4680EAE+ implements a dual-channel, normally closed analog switch architecture using CMOS process technology. Each channel features matched on-resistance (≤0.3Ω difference) and flat on-resistance (≤0.3Ω variation) over its full ±10V signal range, ensuring minimal gain error and THD in precision signal paths.
It supports independent logic supply (VL) decoupled from analog supplies (V+, V−), enabling TTL/CMOS input compatibility across the entire analog supply range. No internal break-before-make timing is implemented-unlike the MAX4700-making it suitable for applications requiring simultaneous conduction during state transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 1.25Ω max - ensures minimal voltage drop and power loss at ±10V signal levels with 10mA load |
| RON Match | 0.3Ω max - enables precise channel-to-channel signal tracking in differential or ratiometric circuits |
| RON Flatness | 0.3Ω max - maintains consistent gain and linearity across full ±10V analog input range |
| Off-Leakage Current | 5nA max at +85°C - preserves high-impedance node integrity in sample-and-hold or sensor front-ends |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial, automotive, and wide-range instrumentation rails |
| Logic Compatibility | TTL/CMOS inputs with separate VL pin - allows interface to 3.3V or 5V controllers without level-shifting |
| ESD Protection | >2kV per Method 3015.7 - enhances robustness in handling and board-level ESD events |
Pinout & Package
MAX4680EAE+ is housed in a 16-pin SSOP (Shrink Small Outline Package) with 0.65mm pitch, JEDEC MO-153 compliant, footprint compatible with industry-standard 16-pin SOIC but with 30% smaller area and improved thermal performance.
| 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 isolation and reduce crosstalk |
| 2, 7 | GND | Analog and digital ground reference; must be low-impedance return path for leakage and switching currents |
| 4 | V− | Negative analog supply input; connect to GND for single-supply operation |
| 5 | IN1 / IN2 | Digital control inputs for SW1/SW2; active-low logic controls NC closure (logic 0 = ON) |
| 9, 16 | NC1 / NC2 | Normally closed analog terminals - conduct to COM when IN = 0V |
| 11, 14 | COM1 / COM2 | Common analog nodes - bidirectional signal path shared with NC terminals |
| 12 | VL | Independent logic supply input - sets input threshold and noise margin; can differ from V+/V− |
| 13 | V+ | Positive analog supply input - defines upper rail for rail-to-rail signal handling |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Signal Handling | Supports analog signals from V− to V+ without clipping - essential for full-scale ADC/DAC interfacing |
| Guaranteed RON Match | ≤0.3Ω channel-to-channel mismatch - enables accurate differential measurements and matched filter banks |
| Low Charge Injection | ±60pC typical - minimizes voltage glitch in sample-and-hold and multiplexed sensor systems |
| High Off-Isolation | −53dB typical at 1MHz - suppresses crosstalk between active and inactive channels in dense signal routing |
| Low On-Capacitance | 275pF typical - preserves bandwidth in high-frequency signal paths up to ~10MHz |

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 (normally open) configuration vs. MAX4680EAE+'s dual NC; identical RON, leakage, and supply specs | Suitable where default-open safety state is required (e.g., fail-safe signal disconnect) | Select MAX4690EAE+ when default isolation is mandatory; MAX4680EAE+ preferred for default-conduction paths |
| ADG1419BRUZ | Single-supply only (+5V to +36V); 1.3Ω on-resistance; no dual-supply support; higher 10nA leakage at +85°C | Better suited for cost-sensitive, single-rail industrial PLC I/O modules than bipolar test equipment | Choose ADG1419BRUZ for simplified single-supply designs; retain MAX4680EAE+ for ±15V instrumentation or dual-rail flexibility |
Compared with MAX4690EAE+ (NO), MAX4680EAE+ provides inherent default-closed behavior critical for fail-operational signal paths; versus ADG1419BRUZ, it offers true dual-supply operation and lower leakage-key for high-precision, wide-voltage-range applications.

FAQ
What is the operating temperature range for the MAX4680EAE+?
The MAX4680EAE+ is rated for operation from −40°C to +85°C. This extended industrial temperature range ensures reliable performance in demanding environments such as factory automation, outdoor test gear, and automotive under-hood diagnostics. The device's leakage, on-resistance, and switching times are fully specified across this range, with 5nA max off-leakage guaranteed at +85°C. All electrical characteristics in the MAX4680EAE+ datasheet apply within this interval.
Does the MAX4680EAE+ support dual-supply operation?
Yes, the MAX4680EAE+ supports both single-supply (+4.5V to +36V) and dual-supply (±4.5V to ±20V) configurations. In dual-supply mode, V+ and V− define symmetric rails-for example, ±15V-enabling true bipolar signal handling from −15V to +15V. The separate VL pin maintains TTL/CMOS logic compatibility regardless of analog supply choice. This flexibility makes the MAX4680EAE+ suitable for legacy ±15V instrumentation and modern single-rail systems alike.
What does "NC" mean in the context of the MAX4680EAE+ switch configuration?
In the MAX4680EAE+, "NC" stands for Normally Closed-meaning each switch conducts between COM and NC terminals when its control input (IN) is logic low (0V). When IN is high, the switch opens. This differs from the MAX4690EAE+ (NO) and MAX4700EAE+ (break-before-make). The NC topology provides default-conduction behavior, which is critical in fail-operational systems like safety interlocks or default-bypass signal paths. The MAX4680EAE+ contains two independent NC switches.
Can the MAX4680EAE+ handle rail-to-rail analog signals?
Yes, the MAX4680EAE+ fully supports rail-to-rail analog signal handling-from V− to V+-without clipping or increased distortion. Its CMOS architecture and optimized channel design maintain low on-resistance (1.25Ω max) and flat RON (0.3Ω max variation) across the entire signal range. This capability is verified for ±10V signals under ±15V dual-supply conditions and 0V–10V signals under +12V single-supply operation. Rail-to-rail support makes the MAX4680EAE+ ideal for interfacing with full-scale ADCs, DACs, and op-amp stages.
Is the MAX4680EAE+ pin-compatible with other devices in the MAX4680/MAX4690/MAX4700 family?
Yes, the MAX4680EAE+ shares identical pinout, package (16-pin SSOP), and footprint with MAX4690EAE+ and MAX4700EAE+. All three devices use the same terminal assignments for V+, V−, GND, VL, COM1/COM2, IN1/IN2, and NC1/NC2 (or NO1/NO2). However, functional behavior differs: MAX4680EAE+ is dual-NC, MAX4690EAE+ is dual-NO, and MAX4700EAE+ is mixed with guaranteed break-before-make. Swapping requires logic inversion or circuit redesign-no blind drop-in replacement is possible despite physical compatibility.
