MAX4680CAE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4680CAE is a dual SPST CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated, housed in a 16-pin SSOP package. It operates from +4.5V to +36V single supply or ±4.5V to ±20V dual supplies with TTL/CMOS-compatible logic inputs. The device features a maximum on-resistance of 1.25Ω, matched between channels to 0.3Ω max, and flatness of 0.3Ω max over the signal range. Electrical characteristics include 5nA max off-leakage current at +85°C, 55pC charge injection, and >2kV ESD protection. Operating temperature range is 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Rail-to-Rail analog signal handling capability across the full supply voltage range
• Guaranteed low on-resistance matching and flatness for low-distortion performance
• TTL/CMOS-compatible control inputs independent of analog supply levels

Analog Switches, Multiplexers, Demultiplexers Applications

• Reed relay replacement in automated test equipment
• Data acquisition systems requiring current switching
• Sample-and-hold circuits
• Communication systems and PBX/PABX applications

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'CAE' corresponds to the 16-lead SSOP package and the 0°C to +70°C industrial temperature range as defined in the manufacturer's ordering information. Confirm that the component meets RoHS compliance requirements if applicable to the target assembly process. Cross-reference the datasheet revision date to ensure all electrical specifications align with current manufacturing standards before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4680CAE when normally closed (NC) switch configuration is required, distinguishing it from the MAX4690 (NO) and MAX4700 (mixed). Ensure the application signal range falls within the specified single or dual supply limits. Consider the 1.25Ω on-resistance and 55pC charge injection parameters for signal integrity requirements. Verify that the 16-SSOP package dimensions fit the available PCB footprint constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4680 belongs to the MAX4680/MAX4690/MAX4700 family of dual analog switches designed to replace mechanical relays. While sharing core electrical specifications like on-resistance and supply ranges, the family differentiates based on switch state: MAX4680 provides two NC switches, MAX4690 provides two NO switches, and MAX4700 offers one of each with break-before-make timing. This part specifically utilizes the NC topology.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible substitutes within the same family include the MAX4690CAE (normally open configuration) and MAX4700CAE (mixed configuration). For extended temperature ranges, the MAX4680EAE variant covers -40°C to +85°C. Other packages such as Wide SO (CWE) or Plastic DIP (CPE) are available but require layout adjustments.
