MAX4723EUA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4723EUA+ is a dual single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +1.8V to +5.5V supply and features an on-resistance of 4.5Ω maximum at +3V and 3Ω maximum at +5V. The device includes one normally open and one normally closed channel, offering break-before-make switching with a 1ns delay. Key electrical parameters include a 300MHz bandwidth, 15pF on-channel capacitance, and less than 0.5nA leakage current at +25°C. It supports rail-to-rail signal handling and is CMOS-logic compatible.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm package type matches the 8-pin µMAX specification. Check RoHS compliance status as indicated in official documentation. Ensure storage conditions adhere to moisture sensitivity level requirements to prevent damage prior to assembly.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a combination of normally open and normally closed switches is required within a dual-channel architecture. Consider the 4.5Ω on-resistance limit for applications sensitive to insertion loss. Verify that the logic input levels align with the system's control voltage thresholds for reliable operation across the specified temperature range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4721/MAX4722/MAX4723 family of low-voltage analog switches. While the MAX4721 provides two normally open channels and the MAX4722 offers two normally closed channels, the MAX4723 uniquely combines one of each. All variants share identical pinouts and electrical characteristics except for the switch state configuration.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same package include the MAX4721EUA+ and MAX4722EUA+. These parts share the same pinout and specifications but differ in switch configuration. Cross-referencing with other Maxim dual SPST switches requires verification of on-resistance and voltage compatibility.
