Product details
Overview
MAX4690EWE+T from Maxim Integrated is a dual SPST normally open (NO) CMOS analog switch optimized for rail-to-rail signal routing in precision instrumentation and automated test equipment. 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 of ±15V analog signals in data acquisition systems.
For engineers reviewing the MAX4690EWE+T datasheet, MAX4690EWE+T pinout, MAX4690EWE+T application, or MAX4690EWE+T equivalent, this page provides verified electrical specifications, truth-table-validated switching behavior, package-specific thermal derating, and direct alternatives for reed-relay replacement and sample-and-hold circuit design.
Technical Context
The MAX4690EWE+T implements two independent CMOS transmission gates with TTL/CMOS-compatible control inputs referenced to a dedicated VL pin, ensuring logic compatibility across its full ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operating range. Each switch features matched on-resistance (≤0.3Ω difference) and flat on-resistance (≤0.3Ω variation) over the entire signal range.
It supports rail-to-rail analog signal handling without distortion, achieves −65dB crosstalk and −53dB off-isolation at 1MHz, and exhibits 550pC typical charge injection-critical for minimizing settling error in precision sampling circuits. Break-before-make timing is not guaranteed, as that feature applies only 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 when routing ±10V signals at 10mA. |
| RON Match | 0.3Ω max - guarantees matched gain/attenuation in differential or dual-channel signal paths. |
| RON Flatness | 0.3Ω max - maintains consistent insertion loss across full input signal swing (±10V). |
| Off-Leakage Current | 5nA max at +85°C - preserves high-impedance node integrity in sample-and-hold and sensor front-ends. |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial ±15V and automotive 24V systems. |
| Logic Compatibility | TTL/CMOS via separate VL pin - decouples logic threshold from analog supply, enabling mixed-voltage control. |
| ESD Protection | >2kV per Method 3015.7 - enhances robustness during board handling and system integration. |
Pinout & Package
MAX4690EWE+T is housed in a 16-pin Wide SO (SOIC-W) package with 1.27mm pitch, rated for −40°C to +85°C operation and 762mW maximum power dissipation at +70°C (derated 9.52mW/°C above).
| 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 isolation performance. |
| 2, 7 | GND | Analog and digital ground reference; must be low-impedance for leakage and noise control. |
| 4 | V− | Negative analog supply input; connect to GND for single-supply operation. |
| 9, 16 | NO1, NO2 | Normally open analog switch terminals - conduct only when corresponding IN_ = HIGH. |
| 11, 14 | COM1, COM2 | Common analog ports - bidirectional signal path between COM and NO pins. |
| 12 | VL | Dedicated logic supply input - sets input threshold independently of V+ or V−. |
| 13 | V+ | Positive analog supply input - defines upper rail for rail-to-rail signal handling. |
| 1, 3 | IN1, IN2 | Active-high digital control inputs - drive respective switches ON/OFF with TTL/CMOS levels. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping or distortion - essential for full-scale sensor and DAC output routing. |
| Guaranteed RON match & flatness | 0.3Ω max mismatch and flatness - enables precise gain matching in dual-channel instrumentation amplifiers and ADC front-ends. |
| Dual- or single-supply operation | Operates from ±4.5V to ±20V or +4.5V to +36V - eliminates need for level-shifting in legacy ±15V or modern 24V industrial systems. |
| TTL/CMOS-compatible control | Separate VL pin allows 3.3V or 5V logic control while analog supplies run at ±15V - simplifies mixed-voltage PCB design. |
| Low charge injection (550pC typ) | Minimizes voltage glitch on sampled nodes - critical for sub-12-bit accuracy in sample-and-hold and multiplexed ADC applications. |

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 |
|---|---|---|---|
| ADG1419BRUZ | 1.3Ω RON, ±15V supply, but requires same supply for logic and analog (no VL pin); 16-TSSOP package. | Lacks separate VL pin - unsuitable when logic and analog supplies differ; better for space-constrained layouts. | Select ADG1419BRUZ if board uses only one supply domain and TSSOP footprint is preferred. |
| TS5A3157DCKR | 0.75Ω RON, +1.65V to +5.5V single supply only; no dual-supply capability; 6-pin SC70 package. | Not compatible with ±15V or >5.5V systems; limited to low-voltage portable/audio applications. | Select TS5A3157DCKR only for battery-powered 3.3V systems requiring ultra-low RON and minimal footprint. |
Compared with ADG1419BRUZ and TS5A3157DCKR, the MAX4690EWE+T uniquely supports independent logic/analog supplies, rail-to-rail ±20V operation, and guaranteed RON matching - making it the only option among the three qualified for industrial ±15V data acquisition and reed-relay replacement.

FAQ
What is the maximum supply voltage rating for MAX4690EWE+T?
The MAX4690EWE+T supports absolute maximum analog supply ratings of −0.3V to +44V on V+ and +0.3V to −44V on V−, with recommended operating ranges of +4.5V to +36V (single supply) or ±4.5V to ±20V (dual supply). Exceeding these limits risks permanent damage, and proper sequencing (V+ first, then V−, then logic) is required for reliable operation.
Does MAX4690EWE+T support break-before-make switching?
No, the MAX4690EWE+T does not guarantee break-before-make operation. That feature is exclusive to the MAX4700 variant in the same family. The MAX4690EWE+T implements simple SPST NO switches with independent control - simultaneous conduction during transition is possible, so external timing control is required in applications sensitive to short-through conditions.
What is the purpose of the VL pin on MAX4690EWE+T?
The VL pin on MAX4690EWE+T provides a dedicated logic supply reference, allowing TTL/CMOS-compatible input thresholds (0.8V low, 2.4V high) regardless of analog supply voltage. This enables clean 3.3V or 5V microcontroller control even when V+ and V− operate at ±15V - eliminating level shifters and reducing BOM count in mixed-voltage systems.
Can MAX4690EWE+T handle AC signals with negative excursions?
Yes, the MAX4690EWE+T supports true rail-to-rail analog signal handling from V− to V+, including negative voltages when operated in dual-supply mode. With V− = −15V and V+ = +15V, it reliably passes ±15V AC waveforms without clipping or increased distortion, provided signal edges remain within the absolute maximum ratings and proper grounding is maintained.
What package type is used for MAX4690EWE+T?
The MAX4690EWE+T uses a 16-pin Wide SO (SOIC-W) package with 1.27mm lead pitch and exposed pad option not specified. It is rated for −40°C to +85°C operation and has a maximum power dissipation of 762mW at +70°C, derating linearly by 9.52mW/°C above that temperature - critical for thermal design in densely populated industrial PCBs.
