MAX4764ETB+T

Analog Switches - Special Purpose Overview

The MAX4764ETB+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 low on-resistance of 0.6Ω at +2.7V supply. The device supports negative signal throughput down to VCC - 5.5V, enabling distortion-free audio switching. It includes an internal shunt switch to discharge capacitance at NO and NC terminals, reducing click-and-pop sounds. The component is housed in a 10-pin TDFN package with an exposed pad and operates over a temperature range of -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

• Internal shunt resistor automatically discharges capacitance at connection points to minimize audible artifacts during audio signal switching
• Negative signal capability allows signals below ground to pass through without distortion
• Low on-resistance ensures minimal signal loss across the operating voltage range

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 against official manufacturer documentation to confirm package type and temperature range. Ensure compatibility with system logic levels and power supply requirements before integration. Cross-reference pin configurations with the datasheet to prevent layout errors during PCB design.

Analog Switches - Special Purpose Selection Notes

Select this component for applications requiring low-voltage operation and high-fidelity audio signal routing. The integrated shunt switch makes it suitable for portable devices where click-and-pop suppression is critical. Verify that the 10-pin TDFN package fits within the available board space constraints.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4762–MAX4765 family of low-voltage, dual SPDT switches. While variants like the MAX4763 include a comparator for headphone detection, the MAX4764 specifically focuses on audio clarity through its internal shunt mechanism. It shares the same core architecture as other family members but lacks the comparator feature found in select models.

Analog Switches - Special Purpose Replacement Considerations

Direct substitutes within the same family include the MAX4764AETB+T, which offers identical functionality in the same TDFN package. Other family members like the MAX4762ETB+T lack the shunt switch feature and are not functionally equivalent for clickless audio applications.
