MAX4572EAI+T

Analog Switches - Special Purpose Overview

The MAX4572EAI+T is a serially controlled, clickless audio and video switch IC manufactured by Analog Devices under the Maxim Integrated brand. It integrates eight independent switches within a single package, configured as two SPST and six SPDT units. The device operates on a single supply voltage ranging from 2.7 V to 5.25 V. Key electrical specifications include a maximum on-resistance of 35 Ohms, a bandwidth of 150 MHz, and typical turn-on and turn-off times of 8 ns and 3 ns, respectively. It provides high channel isolation, with typical values of -90 dB for SPST and -50 dB for SPDT configurations. The component is housed in a 28-pin QSOP package and supports surface mount installation.

Analog Switches - Special Purpose Feature Summary

• Serial control interface reduces pin count and simplifies system integration
• Clickless operation eliminates audible switching noise in audio applications
• High bandwidth supports wideband signal transmission for video signals

Analog Switches - Special Purpose Applications

• Audio and video signal routing systems
• Portable multimedia devices requiring low power consumption
• Test and measurement equipment signal paths

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix EAI against official datasheets to confirm the industrial temperature range and package type. Confirm RoHS compliance status through manufacturer documentation. Check current availability as distribution channels may report limited stock or discontinuation statuses that vary by region.

Analog Switches - Special Purpose Selection Notes

Select this component when a compact solution for multiple analog signal paths is required. Ensure the system voltage aligns with the 2.7 V to 5.25 V operating range. Verify that the 35 Ohm on-resistance meets the signal integrity requirements for the specific application load.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4572 series of serially controlled switches. It shares functional similarities with other Maxim Integrated video switch ICs but offers a specific combination of SPST and SPDT channels. The EAI suffix typically denotes an extended temperature range and a specific plastic package variant compared to commercial grade options.

Analog Switches - Special Purpose Replacement Considerations

Direct replacements include the MAX4572EWI+T which utilizes a SOIC-28 package instead of QSOP. Other compatible series members like the MAX4562 offer different channel counts and should be evaluated for pin compatibility and performance matching.
