Product details
Overview
MAX4690EAE from Maxim Integrated is a dual SPST normally open (NO) CMOS analog switch optimized for rail-to-rail signal switching 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, operating from +4.5V to +36V single supply or ±4.5V to ±20V dual supplies. Its TTL/CMOS-compatible logic inputs and 16-pin SSOP package support high-density PCB layouts in data acquisition systems.
For engineers reviewing the MAX4690EAE datasheet, MAX4690EAE pinout, MAX4690EAE application, or MAX4690EAE equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, application-specific implementation value, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The MAX4690EAE implements two independent normally open analog switches using complementary MOSFET topologies with matched channel design. Each switch supports rail-to-rail analog voltage handling across its full specified supply range, with on-resistance flatness maintained within 0.3Ω over ±10V signal swing.
It features separate VL logic supply pin enabling consistent TTL/CMOS input thresholds regardless of analog supply voltage, and integrates >2kV ESD protection per Method 3015.7 on all pins. Switching dynamics include 400ns max turn-on time and 300ns max turn-off time at ±10V COM swing with 50Ω load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 1.25Ω max - ensures minimal signal attenuation and voltage drop in low-voltage precision circuits. |
| RON Match | 0.3Ω max - enables accurate differential signal routing and matched gain paths in instrumentation front-ends. |
| Off-Leakage Current | 5nA max at +85°C - preserves signal integrity in high-impedance sample-and-hold and sensor interface nodes. |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial, test, and wide-input-range analog signal chains. |
| Logic Compatibility | TTL/CMOS inputs with dedicated VL pin - guarantees reliable control across mixed-voltage system designs without level shifters. |
| ESD Protection | >2kV per Method 3015.7 - reduces need for external protection components in field-deployable test equipment. |
| Turn-On/Off Time | 400ns / 300ns max - enables sub-microsecond multiplexing in high-speed data acquisition and ATE scan paths. |
Pinout & Package
MAX4690EAE is housed in a 16-pin SSOP (Shrink Small Outline Package) with 0.65mm lead pitch, 5.0mm × 6.2mm body size, and exposed pad not present. Pin functions are validated per Maxim's official MAX4690 pin configuration diagram and truth table.
| 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; must be low-impedance return path for leakage-sensitive applications. |
| 4 | V− | Negative analog supply input; connect to GND for single-supply operation. |
| 5 | IN1 | Digital control input for Switch 1; active-high logic drives NO1 closed when high. |
| 9, 16 | NO1, NO2 | Normally open analog terminals; carry switched signals only when corresponding IN_ is high. |
| 11, 14 | COM1, COM2 | Common analog terminals; serve as bidirectional signal ports connected to NOx when enabled. |
| 12 | VL | Independent logic supply input; sets input threshold independently of V+/V−, enabling mixed-voltage control. |
| 13 | V+ | Positive analog supply input; defines upper rail for rail-to-rail analog signal handling. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Signal Handling | Supports analog signals from V− to V+ without clipping-critical for ±10V industrial sensor interfaces and DAC output routing. |
| Guaranteed RON Flatness | 0.3Ω max variation over full signal range-ensures consistent gain and linearity in audio and measurement signal paths. |
| Break-Before-Make Exclusion | MAX4690EAE is NO-only; no break-before-make guarantee-suitable for non-critical switching where channel overlap is acceptable. |
| Low Charge Injection | 550pC typical-minimizes voltage glitch in sample-and-hold and integrator circuits during switching transitions. |
| High Off-Isolation | −53dB min at 1MHz-suppresses crosstalk between adjacent channels in dense multiplexer arrays. |

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 on-resistance, ±15V dual-supply only, no VL pin, 16-TSSOP package. | Lacks independent logic supply-requires VDD = V+ for TTL compatibility; unsuitable for mixed-voltage control buses. | Select when dual-supply-only operation is acceptable and board layout accommodates TSSOP footprint. |
| TS5A23157DGSR | 0.9Ω on-resistance, +1.65V to +5.5V single supply only, 10-pin VSSOP, no dual-supply capability. | Cannot support >5.5V analog signals-limited to low-voltage portable and battery-powered systems. | Select for cost-sensitive, low-voltage consumer electronics where ±15V operation is unnecessary. |
Compared with MAX4690EAE, ADG1419BRUZ offers tighter RON match but sacrifices logic supply flexibility, while TS5A23157DGSR reduces on-resistance at the expense of analog voltage range and thermal robustness-making MAX4690EAE the optimal choice for industrial-grade, wide-supply, mixed-voltage signal routing.

FAQ
What is the maximum analog signal voltage range supported by the MAX4690EAE?
The MAX4690EAE supports rail-to-rail analog signals from V− to V+, enabling operation across the full supply range. With ±15V dual supplies, it handles ±15V signals; with +12V single supply and V− tied to GND, it supports 0V to +12V signals. Absolute maximum ratings limit V+ to +44V and V− to −44V relative to GND, but sustained operation must stay within the specified supply ranges: +4.5V to +36V (single) or ±4.5V to ±20V (dual). The MAX4690EAE maintains guaranteed performance-including 1.25Ω max on-resistance and 5nA max off-leakage-only within these ranges.
Does the MAX4690EAE provide break-before-make switching behavior?
No, the MAX4690EAE does not provide guaranteed break-before-make switching. It is a dual normally open (NO) switch, and its truth table shows independent channel control with no timing coordination between switches. Break-before-make is explicitly guaranteed only for the MAX4700 variant (one NO + one NC), which specifies 5ns to 125ns tOPEN. For MAX4690EAE, simultaneous activation of both switches may result in momentary channel overlap-designers requiring guaranteed isolation during transition must implement external timing control or select MAX4700EAE instead.
Can the MAX4690EAE operate with different voltages on V+ and VL pins?
Yes, the MAX4690EAE is designed for independent V+ and VL supplies. VL sets the logic input threshold (2.4V high / 0.8V low), while V+ defines the analog positive rail. This allows interfacing with 3.3V or 5V logic controllers even when V+ is +24V or ±15V. The datasheet specifies VL must remain within −0.3V to (V+ + 0.3V); for example, with V+ = +36V, VL may range from −0.3V to +36.3V. This decoupling eliminates level-shifter requirements in mixed-voltage systems-a key advantage over alternatives like TS5A23157DGSR that lack a dedicated VL pin.
What is the thermal performance of the MAX4690EAE in its 16-pin SSOP package?
The MAX4690EAE in 16-pin SSOP has a junction-to-ambient thermal resistance (θJA) of 110°C/W, supporting continuous power dissipation up to 571mW at +70°C ambient (derated by 7.1mW/°C above). At maximum rated junction temperature (+125°C) and +85°C ambient, usable power is ~285mW. Thermal performance is validated across the −40°C to +85°C operating range, with on-resistance increasing only 0.2Ω from −40°C to +85°C at ±15V supplies. No heatsink or forced airflow is required for typical 10mA–50mA channel currents.
How does the MAX4690EAE compare to the MAX4680EAE in terms of switch configuration and use cases?
The MAX4690EAE contains two normally open (NO) switches, while the MAX4680EAE contains two normally closed (NC) switches. This fundamental difference dictates their system roles: MAX4690EAE routes signals only when enabled (safe default = open circuit), ideal for test fixture actuation and signal gating; MAX4680EAE passes signals by default and interrupts them on command, suited for fail-safe shutdown paths or default signal continuity. Both share identical electrical specs (1.25Ω RON, 5nA leakage, same supply ranges), so PCB layout is identical-but logic polarity and safety assumptions differ. Substituting one for the other requires firmware and safety analysis updates.
