MAX4573EWI

Analog Switches - Special Purpose Overview

The MAX4573EWI is a serially controlled, clickless audio/video switch IC manufactured by Analog Devices Inc./Maxim Integrated. It features an 11-channel Single-Pole Single-Throw (SPST) configuration housed in a 28-pin SOIC-Wide package. The device operates on a single supply voltage ranging from 2.7 V to 5.25 V, with a typical operating voltage of 5 V. Key electrical specifications include a maximum on-resistance of 35 Ohms, a bandwidth of 150 MHz, and a maximum turn-on time of 8 ns. The component supports a maximum switch DC current of 10 mA and offers typical off-isolation values of -90 dB and -50 dB.

Analog Switches - Special Purpose Feature Summary

• Serially controlled interface for simplified system integration
• Clickless operation designed to minimize audible switching noise
• High-speed signal switching capabilities suitable for video applications

Analog Switches - Special Purpose Applications

• Audio/Video signal routing systems
• Portable multimedia devices requiring low-noise switching
• Test and measurement equipment signal paths

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'EWI' against official manufacturer documentation to confirm package type and temperature range. Confirm availability status as this series may be subject to discontinuation or limited supply constraints. Ensure compatibility with existing serial control logic levels before procurement.

Analog Switches - Special Purpose Selection Notes

Select this component when a high channel count is required within a single integrated circuit. Compare the 11 SPST configuration against alternatives like the MAX4572 if fewer channels are sufficient. Verify that the 150 MHz bandwidth meets the specific signal frequency requirements of the target application.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4573 family of serially controlled switches. It shares functional similarities with the MAX4571 and MAX4572 but differs in channel count and package options. The EWI suffix typically denotes a wide-body SOIC package with specific industrial or commercial temperature ratings defined by the manufacturer.

Analog Switches - Special Purpose Replacement Considerations

The MAX4573CAI+T and MAX4573CWI-T are verified substitutes within the same product family. These parts share identical electrical characteristics and pinouts, differing primarily in package style and temperature rating. Verify that the replacement suffix matches the required thermal and physical constraints.
