MAX4690EAE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4690EAE+ is a dual SPST CMOS analog switch featuring a maximum on-resistance of 1.25Ω with guaranteed matching of 0.3Ω and flatness of 0.3Ω over the signal range. It supports single supplies from +4.5V to +36V or dual supplies from ±4.5V to ±20V, utilizing a separate logic supply pin for TTL/CMOS compatibility. The device handles rail-to-rail analog signals with off-leakage current limited to 5nA max at +85°C. Packaged in a 16-lead SSOP, it operates within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against official Analog Devices documentation to confirm authenticity and specifications. Ensure the ordering suffix matches the required package type and temperature grade. Check for RoHS compliance status as indicated in the manufacturer's product information. Confirm availability through authorized distribution channels.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part for applications requiring low distortion and high reliability compared to mechanical relays. Ensure the design accommodates the specified single or dual supply voltage ranges. Verify that the logic input levels align with the system's TTL or CMOS standards. Consider the thermal dissipation limits when designing for the SSOP package.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4680/MAX4690/MAX4700 family of dual analog switches. The MAX4690 variant specifically provides two normally open switches, distinguishing it from the MAX4680 (normally closed) and MAX4700 (mixed configuration). All variants share similar electrical characteristics regarding on-resistance and leakage currents.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4680EAE+ serves as a functional substitute if normally closed contacts are acceptable. The MAX4700EAE+ offers mixed NO/NC functionality with break-before-make timing. Cross-referencing pinouts and electrical parameters is essential before substitution.
