MAX4680EAE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4680EAE+T is a dual SPST CMOS analog switch in a 16-pin SSOP package. It operates from +4.5V to +36V single supply or ±4.5V to ±20V dual supplies. The device features a maximum on-resistance of 1.25Ω, with guaranteed matching of 0.3Ω and flatness of 0.3Ω over the signal range. It handles rail-to-rail analog signals with off-leakage current limited to 5nA max at +85°C. Turn-on time is typically 90ns (max 175ns) and turn-off time is typically 130ns (max 275ns). Logic inputs are TTL/CMOS compatible via a separate VL pin.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Low on-resistance with guaranteed channel matching and flatness for low-distortion performance
• Rail-to-rail signal handling capability across wide supply voltage ranges
• Separate logic supply pin ensures TTL/CMOS compatibility independent of analog supply

Analog Switches, Multiplexers, Demultiplexers Applications

• Reed relay replacement
• Data acquisition systems
• Test equipment
• Sample-and-hold circuits
• Communication systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity by checking the manufacturer marking against the official datasheet specifications. Confirm the package type matches the required 16-lead SSOP footprint. Ensure the operating temperature range aligns with the -40°C to +85°C rating specified for the E-grade variant. Cross-reference the ordering suffix to confirm the specific configuration and packaging details.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low on-resistance and high linearity are critical for signal integrity. The dual SPST configuration suits applications requiring two independent switching paths. Verify that the control logic levels match the TTL/CMOS requirements supported by the dedicated VL pin. Consider the power dissipation limits relative to the thermal environment of the SSOP package.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4680/MAX4690/MAX4700 family of dual analog switches. The MAX4680 specifically provides two normally closed switches. It serves as a solid-state alternative to mechanical relays, offering higher reliability and smaller board space. The family shares similar electrical characteristics but differs in switch state configurations.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements within the same family include the MAX4690EAE+T (two NO switches) and MAX4700EAE+T (one NO, one NC). Ensure the substitute maintains the same 16-SSOP package and electrical ratings if pinout or functionality changes.
