MAX4685EUB+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4685EUB+ is a low on-resistance, dual single-pole/double-throw (SPDT) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +1.8V to +5.5V supply and features a maximum on-resistance of 0.8Ω for both normally open and normally closed switches at a +2.7V supply. The device provides rail-to-rail signal handling, 1.8V logic compatibility, and break-before-make switching action with turn-on and turn-off times of 50ns and 30ns respectively. Packaged in a 10-pin μMAX format, it offers low leakage currents and high off-isolation suitable for portable applications.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and RoHS compliance status. Ensure that the procurement channel sources the component directly from authorized distributors or the manufacturer to guarantee authenticity. Confirm availability and lead times through verified supplier channels prior to finalizing orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4685EUB+ when symmetrical on-resistance is required for both normally open and normally closed paths. This model differs from the MAX4684 which offers asymmetrical resistance values. Consider the 10-pin μMAX package for standard surface mount assembly requirements. Evaluate the operating temperature range and supply voltage constraints to ensure compatibility with the target system design.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4685 belongs to the MAX4684/MAX4685 family of low-voltage analog switches designed for space-constrained portable electronics. These devices utilize BiCMOS process technology to achieve low on-resistance and fast switching speeds. The EUB+ suffix indicates a 10-pin μMAX package with lead-free/RoHS-compliant construction, distinguishing it from UCSP or TDFN variants within the same functional family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4684 serves as a functional alternative if asymmetrical on-resistance between NO and NC switches is acceptable. Verify pinout compatibility and electrical specifications such as on-resistance symmetry and switching speeds before substituting.
