MAX4602EWE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4602EWE is a quad single-pole single-throw (SPST) normally open CMOS analog switch housed in a 16-pin Wide SOIC package. It operates from a single supply of +4.5V to +36V or dual supplies of ±4.5V to ±20V. The device features a maximum on-resistance of 2.5Ω, with guaranteed channel matching and flatness of 0.5Ω max over the signal range. Key electrical parameters include a turn-on time of 250ns, turn-off time of 350ns, off-leakage current of 2.5nA max at +85°C, and charge injection of 120pC. It supports continuous currents up to ±200mA and provides ESD protection exceeding 2000V.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EWE' corresponds to the -40°C to +85°C temperature range and 16-Wide SOIC package configuration. Confirm RoHS compliance status as indicated by the '+' designation in the ordering information. Ensure the design accounts for the absolute maximum ratings regarding power dissipation and thermal derating requirements for surface-mount installation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four independent normally open analog switches are required within a compact footprint. The MAX4602 is distinct from the MAX4601 (normally closed) and MAX4603 (mixed NC/NO). Verify that the application signal levels remain within the specified input voltage range relative to the chosen supply configuration to prevent internal diode clamping issues.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4602 belongs to the MAX4601/MAX4602/MAX4603 family of 2.5Ω quad SPST CMOS analog switches manufactured by Maxim Integrated (now Analog Devices). These devices are designed to replace mechanical relays in applications requiring high reliability and reduced board space. The family shares identical pinouts and core electrical characteristics, differing primarily in the logical state of the switches when the control input is low.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same package and specification include the MAX4602CAE (SSOP), MAX4602CPE (DIP), MAX4602EAE (SSOP), and MAX4602EPE (DIP). Cross-family replacements like the MAX4604 differ significantly in on-resistance and switch type.
