MAX4731EBL+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4731EBL+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. The device features guaranteed on-resistance of 50Ω maximum at +3V and 25Ω maximum at +5V, with channel matching of 3.5Ω maximum at +3V. It consumes less than 0.5nW quiescent power and offers -108dB crosstalk and -72dB off-isolation at 1MHz. The component is housed in a 9-bump UCSP package measuring 1.52mm x 1.52mm.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix EBL corresponds to the 9-bump UCSP package variant when sourcing. Confirm that the component meets RoHS compliance standards as indicated in official documentation. Ensure compatibility with the required operating temperature range of -40°C to +85°C for your application environment before finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring minimal board space due to its compact UCSP packaging. Consider the MAX4731 specifically if two normally open switches are needed, as opposed to the NC variants in the series. Evaluate the 50Ω on-resistance specifications against your signal integrity requirements at the target supply voltage.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4731/MAX4732/MAX4733 family of low-voltage dual SPST analog switches. The family shares core electrical characteristics but differs in switch configuration: MAX4731 has two NO switches, MAX4732 has two NC switches, and MAX4733 has one NO and one NC switch. All variants support single-supply operation and offer similar performance metrics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include MAX4732EBL+T and MAX4733EBL+T, provided the switch configuration matches the circuit design. Other packages such as TDFN or µMAX may serve as alternatives if footprint constraints allow.
