MAX4572EAI+

Analog Switches - Special Purpose Overview

The MAX4572EAI+ is a serially controlled analog switch featuring two SPST and six SPDT switches in a 28-pin SSOP package. It operates on a single supply from +2.7V to +5.25V with a maximum on-resistance of 35Ω. The device utilizes a 2-wire I²C-compatible interface for control. Key performance metrics include -90dB audio off-isolation at 20kHz, -50dB video off-isolation at 10MHz, and a bandwidth exceeding 150MHz. It supports selectable soft switching mode for clickless audio operation and functions within temperature ranges of -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

• Configurable soft or hard switching modes to eliminate audible clicks during audio signal routing
• Integrated 2-wire I²C-compatible serial interface for simplified microprocessor control
• High isolation performance with -90dB audio off-isolation and -50dB video off-isolation

Analog Switches - Special Purpose Applications

• Set-Top Boxes
• Audio Systems
• PC Multimedia Boards
• Video Conferencing Systems

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix EAI against official documentation to confirm the extended temperature range (-40°C to +85°C) and SSOP-28 package type. Ensure compatibility with the required I²C bus voltage levels and address configuration pins A0 and A1 before finalizing procurement specifications.

Analog Switches - Special Purpose Selection Notes

Select this component when a combination of SPST and SPDT switching is required within a single package. The MAX4572EAI+ is suitable for designs needing high bandwidth and low distortion. Verify that the system architecture supports the 2-wire I²C protocol and that the power supply remains within the specified 2.7V to 5.25V range for optimal performance.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4571–MAX4574 family of serially controlled audio/video switches. While the MAX4571 and MAX4573 contain eleven SPST switches, the MAX4572 and MAX4574 variants provide a mixed configuration of two SPST and six SPDT switches. All devices in this series share similar electrical characteristics and interface protocols.

Analog Switches - Special Purpose Replacement Considerations

The MAX4572CAI+ serves as a commercial grade alternative with an operating temperature range of 0°C to +70°C. Other family members like the MAX4571EAI+ offer different switch configurations but maintain compatible interfaces.
