Product details
Overview
MAX4680EWE from Maxim Integrated is a dual SPST 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, operating from +4.5V to +36V single supply or ±4.5V to ±20V dual supplies - ideal for reed relay replacement in automated test equipment.
For engineers reviewing the MAX4680EWE datasheet, MAX4680EWE pinout, MAX4680EWE application, or MAX4680EWE equivalent, key selection criteria include guaranteed NC configuration, break-before-make absence (distinguishing it from MAX4700), wide supply range compatibility, and low charge injection (±60pC) critical for sample-and-hold integrity.
Technical Context
The MAX4680EWE implements CMOS-based transmission-gate architecture with independent TTL/CMOS-compatible control inputs (IN1, IN2) referenced to a dedicated logic supply (VL), enabling seamless interfacing across full analog supply ranges. Its dual NC topology ensures default-closed signal paths without external pull-ups or latching circuitry.
On-resistance flatness is guaranteed ≤0.3Ω over the full specified analog signal range (±10V with dual supplies, 0–10V with single supply), and internal ESD protection exceeds 2kV per Method 3015.7 - supporting robust operation in industrial signal acquisition environments where voltage transients and leakage sensitivity coexist.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 1.25Ω max - enables <1mV drop at 10mA, preserving signal fidelity in precision instrumentation |
| RON Match | 0.3Ω max difference between channels - ensures matched gain/attenuation in differential or dual-path circuits |
| Off-Leakage Current | 5nA max at +85°C - minimizes error in high-impedance sensor front-ends and integrator nodes |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial 24V systems and bipolar signal conditioning |
| Logic Compatibility | TTL/CMOS inputs with separate VL pin - allows 3.3V or 5V control logic independent of analog supply rails |
| Charge Injection | ±60pC - limits voltage glitch in sample-and-hold circuits to <60µV on 1nF hold capacitors |
| Off-Isolation | −53dB min at 1MHz - suppresses crosstalk between inactive channels in multiplexed data acquisition |
Pinout & Package
MAX4680EWE is housed in a 16-pin Wide SO (SOIC-W) package, measuring 10.3mm × 7.5mm × 2.3mm, with standard 1.27mm pitch and gull-wing leads suitable for surface-mount reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | N.C. | No internal connection; tie to GND or low-impedance node to improve off-isolation performance |
| 2, 7 | GND | Analog and digital ground reference common to V− and logic return path |
| 4 | V− | Negative analog supply input; connect to GND for single-supply operation |
| 5 | COM1 | Common terminal for first NC switch - primary signal path entry/exit point |
| 9, 16 | NC1, NC2 | Normally closed switch terminals - conduct to COM1/COM2 when IN1/IN2 = logic low |
| 11, 14 | COM2 | Common terminal for second NC switch - electrically isolated from COM1 |
| 12 | VL | Dedicated logic supply input - sets input threshold and noise margin independently of V+/V− |
| 13 | V+ | Positive analog supply input - defines upper rail for rail-to-rail signal handling |
| 1, 3 | IN1, IN2 | Active-low digital control inputs - drive respective switches open (high) or closed (low) |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports signals from V− to V+ without clipping - essential for full-scale sensor output capture |
| Guaranteed NC configuration | Default-closed path eliminates need for external fail-safe biasing in safety-critical monitoring circuits |
| Low on-resistance flatness (0.3Ω max) | Maintains consistent channel gain across ±10V input range - critical for linearity in audio and measurement paths |
| Separate VL logic supply | Enables 3.3V microcontroller control while operating analog section at ±15V - simplifies mixed-voltage system design |
| 2kV ESD protection (HBM) | Withstands handling and board-level transients without latch-up or parameter shift - reduces field failure risk |

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 |
|---|---|---|---|
| MAX4690EWE | Two NO (normally open) switches instead of NC; identical RON, leakage, and supply specs | Requires active drive to close path; unsuitable for fail-safe closed configurations | Select MAX4690EWE only when default-open behavior is required and external pull-downs are acceptable |
| ADG1419BRUZ | Single-supply only (±5V to ±22V dual not supported); 0.9Ω max RON; no separate VL pin | Lacks logic supply independence - ties control voltage to analog rail constraints | Choose ADG1419BRUZ for cost-sensitive single-rail designs where VL decoupling is unnecessary |
Compared with MAX4680EWE, MAX4690EWE provides complementary NO functionality but removes fail-safe closure, while ADG1419BRUZ trades supply flexibility and logic isolation for lower on-resistance - making MAX4680EWE uniquely suited for industrial systems demanding NC default state and mixed-voltage control.

FAQ
What is the default switch state of MAX4680EWE?
The MAX4680EWE features two normally closed (NC) switches: when IN1 and IN2 are logic low (≤0.8V), COM1 connects to NC1 and COM2 connects to NC2. This fail-safe closed state remains active without control power, making MAX4680EWE suitable for safety-critical monitoring paths where signal continuity must be preserved during controller reset or fault conditions.
Does MAX4680EWE support single-supply operation?
Yes, MAX4680EWE supports single-supply operation from +4.5V to +36V. To configure for single supply, connect V− to GND and apply the positive supply to V+. The device maintains rail-to-rail signal handling from 0V to V+, and all electrical specifications-including 1.25Ω max RON and 5nA max off-leakage at +85°C-apply under these conditions as verified in the datasheet's single-supply characterization tables.
What is the purpose of the VL pin on MAX4680EWE?
The VL pin on MAX4680EWE provides a dedicated logic supply reference for the IN1 and IN2 control inputs. This allows TTL/CMOS-compatible switching thresholds (0.8V low, 2.4V high) to be maintained independently of the analog supply rails (V+ and V−). For example, a 3.3V microcontroller can directly drive MAX4680EWE inputs while the analog section operates at ±15V - eliminating level-shifters and ensuring noise-immune digital control.
How does MAX4680EWE differ from MAX4700EWE?
MAX4680EWE contains two NC switches with no break-before-make guarantee, whereas MAX4700EWE integrates one NC and one NO switch with guaranteed break-before-make timing (5ns min, 125ns max). This makes MAX4700EWE appropriate for applications preventing momentary short circuits during channel switching (e.g., power domain isolation), while MAX4680EWE is optimized for simple dual NC routing where simultaneous conduction is acceptable or desired.
What package type is used for MAX4680EWE?
MAX4680EWE is supplied in a 16-pin Wide SO (SOIC-W) package, also documented as "16 Wide SO" in Maxim's ordering information. Its dimensions are 10.3mm × 7.5mm × 2.3mm with 1.27mm lead pitch, RoHS-compliant, and qualified for −40°C to +85°C operation. This package offers higher power dissipation (762mW at +70°C) than the SSOP variant and is compatible with standard SOIC footprints and reflow profiles.
