MAX4684EUB+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4684EUB+T is a 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 low on-resistance, with the NC switch at 0.5Ω max and the NO switch at 0.8Ω max at a +2.7V supply. The device provides break-before-make switching action with a turn-on time of 50ns max and a turn-off time of 30ns max. It includes 1.8V logic compatibility, -68dB crosstalk at 100kHz, and 1nA max leakage current. The component is housed in a 10-pin μMAX package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm the exact package type and RoHS compliance status. Ensure that the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity and traceability. Cross-reference the part number with the latest datasheet revision history to confirm all electrical characteristics remain unchanged.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring low-voltage operation between 1.8V and 5.5V with minimal signal distortion. The asymmetrical on-resistance makes it suitable for driving internal speakers versus external headsets. Verify that the system's digital control inputs align with the specified 1.8V logic thresholds to ensure reliable switching performance under varying supply conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4684/MAX4685 family of low on-resistance, low-voltage analog switches. While the MAX4685 offers symmetrical on-resistance for both switches, the MAX4684 variant specifically provides distinct resistance values for its normally closed and normally open paths. Both variants share identical packaging options and dynamic switching characteristics within the same operational envelope.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4685EUB+T serves as a direct functional substitute within the same series, offering symmetrical on-resistance instead of the asymmetrical profile found in the MAX4684. Designers must evaluate whether the specific resistance differences impact their circuit requirements before swapping these parts.
