MAX4764ETB+TGA8

Analog Switches - Special Purpose Overview

The MAX4764ETB+TGA8 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, ensuring distortion-free audio switching. It includes an internal shunt switch to discharge capacitance at NO and NC terminals, reducing click-and-pop sounds. Operating temperature range is -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

• Dual SPDT switches with negative signal capability for distortion-free audio
• Internal shunt switch reduces audible click-and-pop sounds during switching
• Low on-resistance of 0.6Ω at +2.7V supply voltage
• Operates from +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 exact ordering suffix '+TGA8' against official Maxim/Analog Devices documentation, as standard listings typically show '+T'. Confirm package type matches TDFN-10 specifications. Ensure compatibility with -40°C to +85°C operating temperature range requirements for your specific application environment.

Analog Switches - Special Purpose Selection Notes

Select this component when designing low-voltage audio signal paths requiring dual SPDT switching. The integrated shunt switch is critical for applications sensitive to audible switching artifacts. Ensure supply voltage remains within the +1.8V to +5.5V range. Consider the TDFN-10 package constraints for thermal management and PCB layout.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4762–MAX4764/MAX4764A/MAX4765 family of low-voltage, dual SPDT, audio clickless switches. The MAX4764 variant specifically distinguishes itself by including an internal shunt switch for noise reduction, unlike the MAX4762 which lacks both the comparator and shunt features.

Analog Switches - Special Purpose Replacement Considerations

Direct substitutes within the same family include MAX4764EUB (µMAX package) or MAX4764EBC-T (UCSP package). For devices without the shunt feature, MAX4762 variants are electrically similar but lack click/pop reduction. Comparator-equipped alternatives like MAX4763/MAX4765 offer additional headphone detection capabilities.
