MAX4684EUB+

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 a maximum of 0.5Ω for the NC switch and 0.8Ω for the NO switch at a +2.7V supply. The device provides break-before-make switching action with a turn-on time of 50ns max and turn-off time of 40ns max. It includes 1.8V logic-compatible digital inputs, low crosstalk of -68dB at 100kHz, and high off-isolation of -64dB at 100kHz. 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 Feature Summary

• Dual SPDT configuration with asymmetrical on-resistance for normally closed and normally open switches
• Low voltage operation compatible with 1.8V logic levels
• Rail-to-rail signal handling capability across the entire supply voltage range
• Break-before-make switching action to prevent signal shorting

Analog Switches, Multiplexers, Demultiplexers Applications

• Speaker headset switching
• MP3 players
• Power routing

• Relay replacement

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'EUB' corresponds to the 10-pin μMAX package variant when sourcing. Confirm RoHS compliance status indicated by the '+' symbol in the part number. Ensure the supplier provides documentation matching the official Maxim Integrated datasheet specifications for electrical parameters and thermal characteristics.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low on-resistance and fast switching speeds within a compact surface-mount footprint. Consider the MAX4685 if symmetrical on-resistance values are required for both switch terminals. Evaluate the UCSP or TDFN packages if board space constraints exceed the capabilities of the μMAX form factor.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4684/MAX4685 family of low-voltage, dual SPDT analog switches. The series is designed for portable electronics and battery-powered devices where power consumption and physical size are critical design factors. The EUB suffix specifically denotes the 10-pin μMAX package option within this product line.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4685 serves as a functional alternative within the same family, offering symmetrical on-resistance for both NO and NC switches instead of the asymmetrical configuration found in the MAX4684.
