MAX4722EUA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4722EUA+ 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 offers low leakage current (<0.5nA), high off-isolation (-55dB at 10MHz), and low crosstalk (-80dB at 10MHz). It supports rail-to-rail signal handling, break-before-make switching with a 1ns delay, and has a -3dB bandwidth exceeding 300MHz. The component is housed in an 8-pin µMAX package and functions within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature grade. Ensure compatibility with assembly methods, particularly regarding solder profiles if considering alternative packaging variants. Confirm RoHS compliance status through the latest datasheet revision before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low on-resistance and high bandwidth are required for USB or audio applications. Verify that the normally closed configuration aligns with system requirements. Consider the UCSP reliability implications if opting for wafer-level packages instead of the standard µMAX form factor provided in this part number.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX4721/MAX4722/MAX4723 family of low-voltage analog switches. While sharing core electrical characteristics, the MAX4722 specifically provides two normally closed channels, distinguishing it from the MAX4721 (normally open) and MAX4723 (mixed NO/NC). This variation allows designers to choose the appropriate default state for their application without external pull-downs.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include the MAX4721EUA+ and MAX4723EUA+. These parts share identical electrical specifications but differ in switch configuration (NO vs NC). Verify pinout compatibility and logical inversion requirements when substituting.
