MAX4731EBL+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4731EBL+ is a dual single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +2.0V to +11V supply and handles rail-to-rail analog signals. The device features low leakage current of 0.1nA typical at +25°C and consumes less than 0.5nW typical quiescent power. At +5V, the on-resistance is guaranteed at 25Ω maximum with 3Ω maximum matching between channels. The package is a 9-bump UCSP measuring 1.52mm x 1.52mm. Operating temperature range is -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix matches the specific package variant required. The EBL suffix indicates the UCSP-9 package configuration. Confirm the temperature grade corresponds to the application environment. Check for RoHS compliance status as indicated in the manufacturer documentation. Ensure the component source is authorized to guarantee authenticity.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when space constraints necessitate a chip-scale package. Choose based on the required supply voltage range up to 11V. Consider the on-resistance specifications relative to the load current requirements. Verify that the logic input levels are compatible with the system's digital interface voltages.

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. Other family members include the MAX4732 with normally closed switches and the MAX4733 with mixed configurations. All share similar electrical characteristics and packaging options.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements within the same family include MAX4732EBL+ and MAX4733EBL+. Verify pin compatibility and switch configuration (NO vs NC) before substitution. Ensure the alternative part supports the required supply voltage and package dimensions.
