Product details
Overview
MAX4662CPE+ from Maxim Integrated is a quad single-pole single-throw (SPST) analog switch with normally open (NO) configuration, designed for rail-to-rail signal routing in precision analog systems. It delivers 2.5Ω max on-resistance, 0.5Ω max on-resistance 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 test equipment and data acquisition.
For engineers reviewing the MAX4662CPE+ datasheet, MAX4662CPE+ pinout, MAX4662CPE+ application, or MAX4662CPE+ equivalent, key selection criteria include guaranteed RON flatness (0.5Ω max), TTL/CMOS-compatible logic inputs with separate VL pin, low charge injection (20pC typ), and 16-pin plastic DIP package compatibility with legacy through-hole layouts.
Technical Context
The MAX4662CPE+ implements CMOS-based transmission-gate architecture with independent channel control, enabling simultaneous or staggered switching of four analog paths without crosstalk-induced coupling beyond –60dB. Its dual-supply capability supports bipolar signal handling (±10V), while the dedicated VL pin decouples logic-level thresholds from analog supply rails - ensuring reliable operation across full V+ and V– ranges.
On-resistance remains flat (≤0.5Ω variation) over the entire specified analog signal range (–10V to +10V with dual supplies; 0V to +10V with single supply), and channel-to-channel RON matching is guaranteed ≤0.5Ω - critical for gain-matching in multiplexed instrumentation amplifier front-ends and precision ADC input conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max - ensures minimal voltage drop and gain error in signal-path applications up to ±10V. |
| RON Match Between Channels | 0.5Ω max - enables matched gain/attenuation across multiplexed sensor channels or balanced audio routing. |
| RON Flatness | 0.5Ω max over signal range - preserves linearity in precision sample-and-hold and DAC output buffering. |
| Off-Leakage Current | 5nA max at +85°C - minimizes DC error accumulation in high-impedance integrators and long-duration hold circuits. |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial, avionics, and wide-dynamic-range test equipment rails. |
| Logic Compatibility | TTL/CMOS inputs with separate VL pin - allows interface to 3.3V or 5V controllers regardless of analog supply voltage. |
| Charge Injection | 20pC typical - reduces settling error and pedestal distortion in fast-switching ADC sampling networks. |
Pinout & Package
MAX4662CPE+ uses a 16-pin plastic DIP (dual in-line package) with 0.3-inch body width and standard through-hole footprint - compatible with legacy PCB layouts and manual prototyping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; active-high logic turns corresponding NO switch ON. |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - connect to signal source or load in SPST configuration. |
| 3, 6, 11, 14 | NO1–NO4 | Normally open analog switch outputs - conduct only when respective INx = HIGH. |
| 4 | V− | Negative analog supply rail; tie to GND for single-supply operation. |
| 5 | GND | Ground reference for logic and analog return paths. |
| 12 | VL | Separate logic supply input - sets input threshold independently of V+ and V−. |
| 13 | V+ | Positive analog supply rail - defines upper signal swing limit and power domain. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Signal Handling | Supports analog signals from V− to V+ - eliminates level-shifting in ±15V op-amp systems and unipolar 0–30V sensor interfaces. |
| Guaranteed RON Match & Flatness | 0.5Ω max mismatch and flatness - enables high-fidelity multiplexing in 16-bit+ data acquisition without per-channel calibration. |
| Low Charge Injection (20pC) | Minimizes voltage glitch on high-Z nodes - critical for accurate sampling in switched-capacitor ADCs and integrator reset paths. |
| 2kV ESD Protection | Per Method 3015.7 - enhances robustness during board handling and field deployment in industrial environments. |
| Break-Before-Make Exclusion | Not implemented - MAX4662CPE+ is NO-only; avoids unintended shorting in shared-bus configurations requiring strict isolation. |
Applications
| Reed Relay Replacement | Test Equipment Signal Routing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG465BRZ | Quad SPST NO, 4.5Ω max RON, 16-pin SOIC, no VL pin - logic tied to V+. | Higher RON and no independent logic supply limits use in mixed-voltage systems. | Select when board space favors SOIC and supply rails are fixed at 5V/12V with no need for VL decoupling. |
| TS5A3157DCKR | Single SPST NO, 0.75Ω max RON, 6-pin SC70 - not quad, lower voltage rating (+5.5V max). | Cannot replace quad functionality without four discrete devices; unsuitable for ±15V or >12V systems. | Choose only for low-voltage, space-constrained single-channel routing where ultra-low RON outweighs channel count. |
Compared with ADG465BRZ and TS5A3157DCKR, MAX4662CPE+ uniquely combines quad NO topology, 2.5Ω RON, rail-to-rail operation up to ±20V, and independent VL logic supply - making it the only option among the three qualified for high-accuracy, multi-channel, mixed-supply industrial and avionics signal routing.

FAQ
What is the maximum analog signal voltage range supported by the MAX4662CPE+?
The MAX4662CPE+ supports rail-to-rail analog signals from V− to V+, with absolute maximum ratings of –44V to +44V across V+ and V−. In dual-supply mode (±15V), it handles ±10V signals; in single-supply mode (+12V), it routes 0V to +10V signals. The MAX4662CPE+ datasheet specifies guaranteed operation over ±10V with ±15V supplies and 0V to +10V with +12V supplies - all within its 2.5Ω RON spec.
Does the MAX4662CPE+ require external protection diodes for overvoltage conditions?
No - the MAX4662CPE+ integrates internal protection diodes on all analog pins (COM, NO, IN), limiting forward current per Absolute Maximum Ratings. However, Maxim recommends external series diodes (e.g., 1N4148) on V+ and V− if supply sequencing cannot be controlled, as shown in Figure 1 of the MAX4662CPE+ datasheet. This prevents latch-up during power-up but reduces usable signal range by ~0.7V.
Can the MAX4662CPE+ operate with a 3.3V logic supply while using ±15V analog supplies?
Yes - the MAX4662CPE+ features a dedicated VL pin that accepts 3.3V or 5V logic supplies independently of V+ and V−. With VL = 3.3V, INx inputs recognize 0.8V as logic low and 2.4V as logic high, enabling direct interfacing to 3.3V microcontrollers even when analog rails are ±15V. This separation is explicitly guaranteed in the MAX4662CPE+ Electrical Characteristics table under "Logic Input Voltage Low/High".
Is the MAX4662CPE+ pin-compatible with other variants in the MAX466x family?
Yes - all MAX466x variants (MAX4661/MAX4662/MAX4663) share identical 16-pin DIP, SO, and SSOP footprints and pinouts. The MAX4662CPE+ uses the same pin configuration as MAX4661CPE+ and MAX4663CPE+, differing only in internal switch type (NO vs. NC vs. mixed). This allows drop-in replacement in existing layouts when changing from NC to NO topology, provided logic polarity and break-before-make requirements are verified.
What is the thermal performance of the MAX4662CPE+ in plastic DIP package at +70°C ambient?
In the 16-pin plastic DIP package, the MAX4662CPE+ has a thermal resistance θJA of 10.53°C/W and a maximum continuous power dissipation of 842mW at +70°C ambient (derated above that point). At full 200mA per channel and 2.5Ω RON, worst-case power per switch is 100mW - well within safe operating limits. The MAX4662CPE+ datasheet confirms operation from 0°C to +70°C for the 'C' grade, with no derating required at rated loads.
