MAX4690EWE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4690EWE is a dual single-pole single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a +4.5V to +36V single supply or ±4.5V to ±20V dual supplies, featuring TTL/CMOS-compatible control inputs. The device provides two normally open switches with a maximum on-resistance of 1.25Ω and an off-leakage current of only 5nA at +85°C. Designed for low-distortion applications, it handles rail-to-rail analog signals and offers greater reliability than mechanical relays while requiring less board space.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dual SPST configuration with guaranteed on-resistance matching between channels
• Rail-to-Rail signal handling capability across the full supply range
• TTL/CMOS-compatible logic control inputs ensuring broad compatibility
• High ESD protection rating exceeding 2kV per Method 3015.7

Analog Switches, Multiplexers, Demultiplexers Applications

• Reed relay replacement in compact designs
• Data acquisition systems requiring low distortion
• Test equipment and sample-and-hold circuits
• Communication systems and PBX/PABX networks

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. Confirm that the component meets RoHS standards if required by your manufacturing process. Ensure proper power-supply sequencing during installation to prevent damage, as CMOS devices are sensitive to input voltage levels relative to supply rails.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual-channel analog switch with low on-resistance is required. It is suitable for replacing electromechanical relays where size and reliability are critical. Consider the MAX4680 for normally closed configurations or the MAX4700 if break-before-make switching is necessary. Ensure the application voltage stays within the specified single or dual supply limits.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4680/MAX4690/MAX4700 family of dual analog switches. While functionally similar, the MAX4690 specifically features two normally open switches, distinguishing it from the MAX4680 (two NC) and MAX4700 (one NO, one NC). All variants share the same low on-resistance and high isolation characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible substitutes include the MAX4680EWE and MAX4690CAE. Note that the 'C' suffix indicates a commercial temperature range (0°C to +70°C), whereas the 'E' suffix denotes industrial range (-40°C to +85°C). Verify thermal requirements before substituting.
