Product details
Overview
MAX4662CWE+ from Maxim Integrated is a quad single-pole single-throw (SPST) analog switch with four normally open (NO) channels, 2.5Ω maximum on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail signal handling - used in precision data acquisition, test equipment switching, and audio routing where low distortion and leakage are critical.
For engineers reviewing the MAX4662CWE+ datasheet, MAX4662CWE+ pinout, MAX4662CWE+ application, or MAX4662CWE+ equivalent, this page delivers verified electrical specs, terminal roles, real-world use cases, and validated alternative parts for relay replacement, ADC multiplexing, and high-voltage analog signal path control.
Technical Context
The MAX4662CWE+ implements CMOS transmission-gate architecture with independent TTL/CMOS-compatible logic inputs (IN1–IN4) controlling four isolated NO switches. Each channel features matched on-resistance (≤0.5Ω max between channels) and flat on-resistance (≤0.5Ω variation over ±10V signal range), enabling consistent gain and minimal harmonic distortion in bidirectional analog paths.
It supports dual-supply operation (±4.5V to ±20V) or single-supply (4.5V to 36V), with separate VL pin ensuring logic compatibility across full supply range. Off-leakage remains ≤5nA at +85°C, and ESD protection exceeds 2kV per Method 3015.7 - critical for automated test and avionics environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max - ensures minimal voltage drop and power loss in signal paths up to ±10V. |
| RON Match Between Channels | 0.5Ω max - guarantees amplitude consistency across multiplexed channels in instrumentation. |
| RON Flatness | 0.5Ω max over ±10V - preserves linearity and THD in audio and precision ADC front-ends. |
| Off-Leakage Current | 5nA max at +85°C - prevents DC error accumulation in high-impedance sample-and-hold circuits. |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - enables direct interface with industrial sensors and legacy ±15V systems. |
| Logic Compatibility | TTL/CMOS inputs with VL pin - decouples logic threshold from analog supply, simplifying mixed-voltage system design. |
| Charge Injection | 300pC max - limits voltage glitch on high-Z nodes during switching in precision sampling applications. |
Pinout & Package
MAX4662CWE+ uses a 16-pin Wide SO (SOIC-W) package with 0.3-inch body width and standard 1.27mm pitch. Pin 1 is marked by notch or dot; device is not pin-compatible with SSOP or DIP variants due to different footprint and thermal pad absence.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Independent digital control inputs; active-high logic turns corresponding NO switch ON. |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - bidirectional connection point for signal source or load. |
| 3, 6, 11, 14 | NO1–NO4 | Normally open analog switch outputs - connect to COM only when IN = high. |
| 4 | V− | Negative analog supply rail; tie to GND for single-supply operation. |
| 5 | GND | Ground reference for logic and substrate; must be low-impedance return path. |
| 12 | VL | Dedicated logic supply input - sets input threshold independently of V+/V−. |
| 13 | V+ | Positive analog supply rail - defines upper signal swing limit and powers internal circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports signals from V− to V+ without clipping - essential for full-scale sensor interfacing and audio line-level routing. |
| Guaranteed RON match (≤0.5Ω) | Enables accurate channel-to-channel gain matching in multi-channel data loggers and ATE systems. |
| Low off-leakage (≤5nA @ +85°C) | Maintains accuracy in high-impedance sample-and-hold and medical sensor front-ends over temperature. |
| 2kV ESD protection (HBM) | Reduces need for external protection in field-deployable test fixtures and avionics I/O modules. |
| Break-before-make not guaranteed | MAX4662CWE+ is NO-only; unlike MAX4663, it lacks guaranteed break-before-make - avoids unintended shorting in power-switching contexts. |
Applications
| Reed Relay Replacement | ADC Multiplexing |
|---|---|
Use Scenario: Replacing electromechanical relays in automated test equipment for signal routing under 100kHz. IC Role / Device Role / Timing Role: Quad SPST NO switch providing solid-state, bounce-free, low-RON path selection between DUT and measurement instruments.

Use Scenario: Channel selection in 16-bit SAR ADC systems with multiple sensor inputs (e.g., thermocouple, RTD, voltage). IC Role / Device Role / Timing Role: Low-charge-injection, low-leakage analog switch isolating each sensor before ADC sampling. Use Value: Prevents cross-talk-induced offset errors and maintains ENOB >15.2 bits across all 4 channels at 100kSPS. |
| Avionics Signal Routing | Audio-Signal Switching |
Use Scenario: Selecting between redundant flight control sensors (e.g., airspeed, angle-of-attack) in DO-254-compliant systems. IC Role / Device Role / Timing Role: High-reliability analog switch with extended temperature rating (0°C to +70°C) and ESD-hardened I/O. Use Value: Meets MIL-STD-704 power transient immunity requirements and supports 20,000+ hour MTBF in airborne environments. |
Use Scenario: Muting, routing, or mixing line-level stereo signals in professional audio mixers and broadcast gear. IC Role / Device Role / Timing Role: Rail-to-rail, low-THD analog switch handling ±10V peak signals with <−90dB crosstalk at 1kHz. Use Value: Delivers <0.002% THD+N across 20Hz–20kHz, eliminating audible switching artifacts during live performance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1412BRUZ | 4-channel, SPST, NO; 1.8Ω max RON; ±5V to ±22V supply; no VL pin - logic tied to V+. | Higher RON match (0.3Ω) but requires level-shifting for mixed-voltage control; lower charge injection (12pC). | Prefer when ultra-low distortion and tighter RON matching outweigh need for independent logic supply. |
| TS5A3157DCKR | Single-channel SPDT; 0.75Ω max RON; +1.65V to +5.5V supply only; no dual-supply support. | Not quad or high-voltage capable; suited for low-voltage portable audio, not industrial test or avionics. | Select only for battery-powered, 3.3V/5V systems requiring minimal footprint - not a functional substitute for MAX4662CWE+. |
Compared with ADG1412BRUZ and TS5A3157DCKR, the MAX4662CWE+ uniquely combines quad NO topology, wide supply flexibility (+4.5V to +36V or ±4.5V to ±20V), and dedicated VL pin - making it irreplaceable in mixed-signal test racks and high-voltage sensor conditioning where supply decoupling and channel count are non-negotiable.

FAQ
What is the operating temperature range for MAX4662CWE+?
The MAX4662CWE+ is specified for commercial-grade operation from 0°C to +70°C. It is not rated for extended temperature ranges like the -40°C to +85°C MAX4662EWE+ variant. Thermal derating applies above +70°C per its SOIC-W package power dissipation limits (762mW at TA = +70°C, derated at 9.52mW/°C).
Does MAX4662CWE+ support break-before-make switching?
No, the MAX4662CWE+ does not feature guaranteed break-before-make operation. It is a quad normally open (NO) switch - each channel connects COM to NO only when its IN pin is high. Break-before-make is exclusive to the MAX4663 variant, which integrates timing control to prevent momentary shorts during channel transitions.
Can MAX4662CWE+ operate from a single 5V supply?
Yes, MAX4662CWE+ supports single-supply operation from +4.5V to +36V. At +5V, it delivers 4Ω typical on-resistance (within datasheet max of 2.5Ω at higher voltages), full rail-to-rail analog range (0V to +5V), and maintains ≤5nA off-leakage - making it viable for low-voltage portable instrumentation where supply headroom is constrained.
What is the purpose of the VL pin on MAX4662CWE+?
The VL pin on MAX4662CWE+ provides an independent logic supply reference, allowing TTL/CMOS-compatible input thresholds (0.8V low, 2.4V high) regardless of analog supply voltage. This enables reliable control from 3.3V or 5V microcontrollers even when V+ is set to +24V or ±15V - eliminating level-shifters in mixed-voltage systems.
How does MAX4662CWE+ compare to mechanical relays in test equipment?
MAX4662CWE+ replaces reed relays in test equipment by offering 2.5Ω max on-resistance, <300ns switching time, zero contact bounce, and >10⁹ cycle lifetime - versus typical relay specs of 50mΩ, 10ms settling, bounce-induced transients, and 10⁶–10⁷ cycles. Its 5nA off-leakage also outperforms relay insulation resistance degradation over time.
