MAX4764EUB+T

Analog Switches - Special Purpose Overview

The MAX4764EUB+T is a dual single-pole/double-throw (SPDT) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a +1.8V to +5.5V supply and features negative signal capability, allowing signals below ground to pass without distortion. The device includes an internal shunt switch to automatically discharge capacitance at the NO and NC connection points, reducing click-and-pop sounds in audio applications. It offers low on-resistance of 0.6Ω at +2.7V supply, with on-resistance flatness of 0.25Ω and matching of 0.05Ω. Key electrical parameters include -70dB crosstalk and -65dB off-isolation at 100kHz. The component operates over an extended temperature range of -40°C to +85°C and is housed in a space-saving 10-pin µMAX package.

Analog Switches - Special Purpose Feature Summary

• Negative signal throughput capability allows signals below ground to pass through without distortion
• Internal shunt resistor automatically discharges capacitance at NO and NC terminals to reduce audible click-and-pop sounds
• Low on-resistance with high flatness and matching for accurate signal switching
• Operates from a single +1.8V to +5.5V supply voltage

Analog Switches - Special Purpose Applications

• Cell Phones
• PDAs and Handheld Devices
• Notebook Computers
• MP3 Players

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix '+T' indicates reel packaging when sourcing components. Confirm that the 'E' designation corresponds to the extended industrial temperature range of -40°C to +85°C. Ensure compatibility with the 10-pin µMAX footprint during PCB layout. Cross-reference the manufacturer's latest documentation for any updates to pin configurations or absolute maximum ratings before finalizing procurement specifications.

Analog Switches - Special Purpose Selection Notes

Select this component for applications requiring low-voltage operation and negative rail signal handling. The internal shunt switch makes it suitable for audio paths where minimizing switching noise is critical. Compare against the MAX4762 if shunt functionality is not needed, or the MAX4763/MAX4765 if integrated headphone detection via a comparator is required. Ensure the logic input levels are compatible with the system's control voltages across the entire operating temperature range.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4762–MAX4765 family of low-voltage, dual SPDT audio clickless switches. The MAX4764 variant specifically distinguishes itself by including an internal shunt switch for discharge functionality, unlike the MAX4762 which lacks both the shunt and the comparator found in other family members. All variants share similar core analog performance characteristics and package options.

Analog Switches - Special Purpose Replacement Considerations

Public confirmed substitute part numbers: MAX4762EUB+, MAX4763EUB+, MAX4765EUB+. Verify functional differences such as the presence of a comparator or shunt switch before substitution.
