Analog Devices Inc./Maxim Integrated MAX4662EPE+

Overview

MAX4662EPE+ 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, 0.4Ω typical on-resistance match between channels, and 5nA max off-leakage at +85°C, enabling low-distortion switching in data acquisition and test equipment.

For engineers reviewing the MAX4662EPE+ datasheet, MAX4662EPE+ pinout, MAX4662EPE+ application, or MAX4662EPE+ equivalent, key selection criteria include guaranteed R_ON flatness (0.7Ω max), ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, TTL/CMOS-compatible logic inputs, and 16-pin plastic DIP packaging for through-hole prototyping and industrial control interfaces.

Technical Context

The MAX4662EPE+ implements CMOS transmission-gate architecture with independent channel control, supporting bidirectional analog signal flow across its four NO switches. Its separate VL pin ensures logic-level compatibility across full supply ranges, while internal protection diodes clamp input overvoltage relative to V+ and V−.

Specified for −40°C to +85°C operation, it maintains ≤0.7Ω R_ON flatness over ±10V signal range and achieves 300ns typical turn-off time with 100pF load. Charge injection is limited to 20pC, minimizing transient errors in sample-and-hold and multiplexed ADC front-ends.

FAQ

What is the maximum analog signal voltage range supported by the MAX4662EPE+?

The MAX4662EPE+ supports rail-to-rail analog signals from V− to V+, enabling full utilization of its supply range: ±4.5V to ±20V in dual-supply mode or +4.5V to +36V in single-supply mode. When V− is tied to GND, the device handles 0V to V+ signals without clipping, making MAX4662EPE+ ideal for DC-coupled sensor interfaces and industrial voltage monitoring.

Does the MAX4662EPE+ require external pull-up or pull-down resistors on its logic inputs?

No, the MAX4662EPE+ does not require external biasing on IN1–IN4 pins. Its TTL/CMOS-compatible inputs have defined thresholds (0.8V low, 2.4V high) and leakage current <0.5µA across temperature, allowing direct connection to microcontroller GPIOs or FPGA outputs. The dedicated VL pin decouples logic threshold from analog supply, ensuring reliable switching even with mismatched V+ and logic voltage domains in MAX4662EPE+ designs.

Can the MAX4662EPE+ be used in a dual-supply configuration with asymmetric voltages, such as +12V and −5V?

Yes, the MAX4662EPE+ supports asymmetric dual supplies as long as V+ to V− differential remains ≤44V and each supply stays within absolute maximum ratings (V+ ≤ +44V vs GND, V− ≥ −44V vs GND). For example, +12V and −5V yields 17V differential - well within spec. However, signal swing is constrained to V− to V+, so analog range becomes −5V to +12V. This flexibility makes MAX4662EPE+ suitable for mixed-signal systems with disparate supply domains.

How does the MAX4662EPE+ compare to the MAX4663EPE+ in terms of switching behavior?

The MAX4662EPE+ implements four independent normally open (NO) switches with no break-before-make timing guarantee, whereas the MAX4663EPE+ integrates two NO and two NC switches with guaranteed break-before-make (5ns min, 125ns max) to prevent momentary shorts during state transitions. If your design requires simultaneous channel reconfiguration without cross-conduction risk - such as in H-bridge control or analog mux sequencing - MAX4663EPE+ is required; otherwise, MAX4662EPE+ provides simpler, lower-cost NO-only routing.

Is the MAX4662EPE+ RoHS compliant and lead-free?

Yes, the MAX4662EPE+ is RoHS compliant and features lead-free (Pb-free) terminations per JEDEC J-STD-609. The "+" suffix in the part number explicitly denotes lead-free, halogen-free, and RoHS-compliant packaging. This applies to the 16-pin plastic DIP variant (EPE grade), ensuring compliance for industrial and medical products sold in EU, China, and other regulated markets where MAX4662EPE+ is deployed.
