MAX4680EWE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4680EWE is a dual SPST CMOS analog switch in a 16-pin Wide SO package. It features a maximum on-resistance of 1.25Ω with guaranteed matching and flatness of 0.3Ω over the signal range. The device handles rail-to-rail analog signals with off-leakage current of 5nA max at +85°C. It operates from +4.5V to +36V single supply or ±4.5V to ±20V dual supplies, with TTL/CMOS-compatible logic inputs.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' for industrial temperature range (-40°C to +85°C) and 'WE' for the 16-Wide SOIC package against the official Analog Devices ordering guide. Confirm RoHS compliance status as indicated by the '+' suffix if required for the assembly process. Cross-reference the datasheet revision date to ensure all electrical characteristics match the design requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low distortion and high reliability are required compared to mechanical relays. Ensure the application voltage stays within the +4.5V to +36V single or ±4.5V to ±20V dual supply limits. Consider the 1.25Ω max on-resistance for signal integrity. Verify that the 16-pin Wide SOIC footprint fits the PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4680/MAX4690/MAX4700 family of dual SPST CMOS analog switches. The MAX4680 variant specifically provides two normally closed (NC) switches. Other family members include the MAX4690 (two NO switches) and MAX4700 (one NC, one NO with break-before-make). All share similar electrical characteristics and packaging options.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible substitutes within the same family include MAX4690EWE (normally open configuration) and MAX4700EWE (mixed configuration with break-before-make). Ensure the replacement matches the required switch state (NC vs NO) and timing characteristics.
