MAX4731EUA+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4731EUA+T is a dual single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +2V to +11V supply and handles rail-to-rail analog signals with low leakage current of 0.1nA typical and quiescent power consumption under 0.5nW. The device features an on-resistance of 50Ω maximum at +3V and 25Ω maximum at +5V, with channel matching of 3.5Ω maximum at +3V and 3Ω maximum at +5V. It is housed in an 8-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 to confirm the package type and temperature grade. Ensure compatibility with the intended supply voltage range and logic levels. Confirm that the component meets all required electrical specifications for the target application environment before integration into the design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low power consumption and small form factor. Consider the on-resistance variation across the signal range and temperature. Verify that the input logic levels match the system voltage when operating outside standard +5V conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4731/MAX4732/MAX4733 family of low-voltage dual SPST analog switches. The MAX4731 variant specifically provides two normally open switches, distinguishing it from the normally closed or mixed configurations available in other members of the series.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes within the same family include the MAX4732EUA+T (normally closed) and MAX4733EUA+T (mixed NO/NC). Verify pinout compatibility and functional requirements before substitution.
