Product details
Overview
MAX4690CPE+ from Maxim Integrated is a dual SPST normally open (NO) CMOS analog switch with 1.25Ω max on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail signal handling up to ±10V. It features matched on-resistance (≤0.3Ω), flat on-resistance (≤0.3Ω), and 5nA max off-leakage at +85°C - ideal for precision data acquisition and automatic test equipment where mechanical relay replacement is required.
For engineers reviewing the MAX4690CPE+ datasheet, MAX4690CPE+ pinout, MAX4690CPE+ application, or MAX4690CPE+ equivalent, key selection criteria include guaranteed NO configuration, dual- or single-supply flexibility, TTL/CMOS-compatible logic inputs via dedicated VL pin, and ESD robustness (>2kV per Method 3015.7).
Technical Context
The MAX4690CPE+ implements two independent normally open analog switches in a single monolithic CMOS process, each with matched and flat on-resistance over its full ±10V signal range. Its separate VL pin enables logic-level compatibility across the entire analog supply range, decoupling control voltage from V+/V−.
Switching is controlled by two independent digital inputs (IN1, IN2), driving complementary MOSFET pairs per channel. Break-before-make timing is not guaranteed (unlike MAX4700); this part is strictly NO-only with no internal break-before-make circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 1.25Ω max - ensures minimal voltage drop and power loss in signal paths carrying up to ±200mA continuous current. |
| RON Match Between Channels | 0.3Ω max - enables precise differential or ratiometric measurements without calibration for channel-to-channel gain mismatch. |
| RON Flatness | 0.3Ω max over ±10V - maintains consistent gain and linearity across full analog input range, critical for audio and instrumentation. |
| 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, automotive, and legacy ±15V systems without level-shifting. |
| Logic Supply (VL) | +2.4V to +5.5V - guarantees TTL/CMOS compatibility regardless of analog supply voltage, simplifying mixed-voltage system design. |
| ESD Protection | >2kV HBM - reduces need for external protection components in board-level ESD-prone environments. |
Pinout & Package
MAX4690CPE+ is housed in a 16-pin plastic DIP package (0.3-inch width), through-hole mountable, rated for 0°C to +70°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | N.C. | No internal connection; recommended to tie to GND for improved off-isolation and noise immunity. |
| 2, 7 | GND | Analog and digital ground reference; must be low-impedance for leakage and crosstalk control. |
| 4 | V− | Negative analog supply input; connect to GND for single-supply use. |
| 5 | COM1 | Common terminal of first NO switch; carries full signal current (±200mA). |
| 9, 16 | NO1, NO2 | Normally open switch terminals; open-circuit when INx = 0, closed when INx = 1. |
| 11, 14 | COM2 | Common terminal of second NO switch; electrically isolated from COM1. |
| 12 | VL | Dedicated logic supply input; sets input threshold (0.8V/2.4V) independently of 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+, enabling full utilization of ±15V or +12V supplies without clipping. |
| Guaranteed NO Configuration | Ensures predictable default-open state during power-up or logic fault, critical for safety-critical signal gating. |
| Separate VL Pin | Decouples logic interface from analog supply rails, eliminating need for level shifters in mixed-voltage systems. |
| Low Charge Injection (550pC) | Minimizes voltage glitch on high-impedance nodes (e.g., sample-and-hold capacitors), preserving measurement accuracy. |
| High Off-Isolation (−53dB) | Reduces crosstalk between active and inactive channels, essential in multi-channel multiplexing applications. |
Applications
| Reed Relay Replacement | Data Acquisition Systems |
|---|---|

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 |
|---|---|---|---|
| MAX4690EPE | Same electrical specs, but rated for −40°C to +85°C industrial temperature range. | Suitable for extended-temperature deployments (e.g., outdoor telecom, automotive under-hood). | Select MAX4690EPE when operating outside 0°C–70°C ambient; otherwise MAX4690CPE+ offers cost advantage. |
| ADG1419BRUZ | 1.3Ω RON, ±15V supply, no VL pin - logic thresholds tied to VDD; 1.5nA max off-leakage at +85°C. | Better leakage performance, but requires VDD-aligned logic and lacks supply-voltage-independent input compatibility. | Choose ADG1419BRUZ only if lower leakage dominates design priority and system uses single-supply logic aligned to analog rail. |
Compared with MAX4690EPE, MAX4690CPE+ trades extended temperature capability for lower cost in commercial-grade systems; compared with ADG1419BRUZ, it provides superior logic supply independence and higher off-isolation (−53dB vs. −48dB), at the expense of slightly higher leakage.

FAQ
What is the maximum signal voltage range supported by the MAX4690CPE+?
The MAX4690CPE+ supports rail-to-rail analog signals from V− to V+, with absolute maximum ratings of −44V to +44V across V+ and V−. In standard operation, it handles ±10V signals with guaranteed 1.25Ω max on-resistance and ≤0.3Ω flatness. For single-supply use, V− = GND and signals swing from 0V to V+ (up to +36V), maintaining full specification compliance.
Does the MAX4690CPE+ support break-before-make switching?
No, the MAX4690CPE+ does not support break-before-make switching. It is a dual normally open (NO) switch with independent channel control. Break-before-make functionality is exclusive to the MAX4700 variant in the same family. Using MAX4690CPE+ in applications requiring break-before-make may cause momentary short-circuits if both switches are activated simultaneously.
Can the MAX4690CPE+ operate from a single +5V supply?
No, the MAX4690CPE+ requires a minimum analog supply of +4.5V, but +5V is insufficient for rail-to-rail operation with meaningful signal headroom. At +5V single supply, the usable signal range is limited to approximately 0.3V–4.7V due to on-resistance voltage drop and internal FET thresholds. For true rail-to-rail performance, use ≥+12V single supply or ±5V dual supply.
How is logic compatibility maintained across wide analog supply ranges in the MAX4690CPE+?
The MAX4690CPE+ achieves logic compatibility across its full analog supply range (+4.5V to +36V or ±4.5V to ±20V) via a dedicated VL pin. This pin accepts a fixed +2.4V to +5.5V logic supply, setting guaranteed TTL/CMOS input thresholds (0.8V low, 2.4V high) independent of V+ or V−. This eliminates level-shifter requirements in mixed-rail systems.
What is the thermal performance of the MAX4690CPE+ in its 16-pin DIP package?
In its 16-pin plastic DIP package, the MAX4690CPE+ has a thermal resistance θJA of 10.53°C/W, allowing 842mW maximum continuous power dissipation at +70°C ambient. Derating is linear above +70°C (−10.53mW/°C). At full ±200mA load per channel and 1.25Ω RON, power dissipation remains well below this limit - ~50mW per switch - ensuring stable operation without heatsinking.
