MAX4764AEUB+

Analog Switches - Special Purpose Overview

The MAX4764AEUB+ is a low-voltage, dual single-pole/double-throw (SPDT) analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates from a +1.8V to +5.5V supply and features negative signal capability for distortion-free throughput down to VCC - 5.5V. The device includes an internal shunt switch to discharge capacitance at NO and NC terminals, reducing click-and-pop sounds in audio applications. Key electrical parameters include a typical 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 an extended temperature range of -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

• Dual SPDT switches with negative signal capability for distortion-free operation below ground potential
• Internal shunt resistor automatically discharges capacitance at connection points to minimize audible switching artifacts
• Low on-resistance with high flatness and channel matching for precise signal routing
• High isolation and low crosstalk characteristics suitable for sensitive audio signal paths

Analog Switches - Special Purpose Applications

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

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 voltage levels and logic thresholds before integration. Cross-reference part numbers with authorized distributors to confirm current availability status and lead times.

Analog Switches - Special Purpose Selection Notes

Select this component when low distortion and negative rail handling are required for audio signals. Consider the internal shunt feature if click-and-pop suppression is critical. Verify that the 10-pin µMAX package fits the PCB layout constraints. Compare on-resistance specifications against other SPDT switches if low insertion loss is a primary design driver.

Analog Switches - Special Purpose Part Context

The MAX4764AEUB+ belongs to the MAX4762–MAX4765 family of low-voltage, dual SPDT analog switches. This series is designed for space-constrained portable electronics requiring high-fidelity signal switching. The 'A' suffix typically denotes an advanced or enhanced version within the product line, while 'EUB+' indicates the specific 10-pin µMAX package and lead-free compliance.

Analog Switches - Special Purpose Replacement Considerations

Direct substitutes within the same family include the MAX4764EUB+ and MAX4764ETB. For designs requiring headphone detection, the MAX4765 variants offer integrated comparators. Ensure any replacement maintains the same package footprint and electrical characteristics, particularly on-resistance and supply voltage range.
