MAX4764EUB+

Analog Switches - Special Purpose Overview

The MAX4764EUB+ 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 discharge capacitance at connection points, reducing audio click-and-pop sounds. Key electrical parameters include a low on-resistance of 0.6Ω at +2.7V supply, 0.25Ω on-resistance flatness, and 0.05Ω on-resistance matching between channels. It offers -70dB crosstalk and -65dB off-isolation at 100kHz, with a total harmonic distortion of 0.01%. The component is housed in a 10-pin µMAX package and operates over a temperature range of -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

• Negative signal throughput capability allows signals below ground to pass through without distortion.
• Internal shunt switch automatically discharges capacitance at NO and NC terminals to reduce audible click-and-pop sounds during audio switching.
• Low on-resistance of 0.6Ω at +2.7V supply voltage ensures minimal signal loss.
• Break-before-make switching action prevents short circuits during channel transitions.

Analog Switches - Special Purpose Applications

• Audio signal routing in portable devices
• Headphone detection and mute functions
• Signal switching in mobile phones and PDAs
• MP3 players and notebook computers

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix and package type against the manufacturer's current documentation to ensure compatibility with your design requirements. Confirm that the component meets all necessary regulatory standards for your target market before finalizing procurement decisions.

Analog Switches - Special Purpose Selection Notes

Select this component when low-voltage operation and negative signal handling are required. The integrated shunt switch makes it suitable for audio applications where minimizing switching noise is critical. Ensure the supply voltage range and package constraints align with your system design.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4762–MAX4765 family of low-voltage, dual SPDT analog switches. The MAX4764 variant specifically distinguishes itself by including an internal shunt switch for audio clickless operation, unlike the MAX4762 which lacks both the comparator and shunt switch.

Analog Switches - Special Purpose Replacement Considerations

The MAX4762EUB+ serves as a direct substitute if the internal shunt switch functionality is not required. Verify pinout compatibility and ensure the absence of the shunt switch does not impact audio performance in your specific application.
