MAX4364ESA+

Audio Amplifiers Overview

The MAX4364ESA+ is a monolithic audio power amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates as a Class AB amplifier within a supply voltage range of 2.7V to 5.5V. The device delivers up to 1.4W of output power into an 8-ohm load. It features integrated protection mechanisms including short-circuit and thermal shutdown capabilities, along with pop-and-click suppression for noise-free operation.

Audio Amplifiers Feature Summary

• Integrated pop-and-click suppression circuitry eliminates audible transients during power-up and power-down sequences.
• Built-in short-circuit and thermal protection safeguards the device under fault conditions.
• Supports single-supply operation with low quiescent current consumption.

Audio Amplifiers Applications

• Portable multimedia devices requiring compact audio amplification
• Battery-powered consumer electronics systems
• Personal digital assistants (PDAs) and mobile communication handsets

Audio Amplifiers Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status and package marking details against official datasheets. Check for obsolescence notices or lifecycle changes prior to procurement. Ensure storage conditions meet moisture sensitivity level requirements.

Audio Amplifiers Selection Notes

Evaluate thermal performance based on PCB copper area and ambient temperature constraints. Verify that the selected supply voltage remains within the specified 2.7V to 5.5V range. Consider the 8-SOIC package dimensions for layout compatibility. Assess load impedance matching to ensure stable operation without oscillation.

Audio Amplifiers Part Context

This component belongs to the Maxim Integrated ultra-small audio amplifier family designed for space-constrained portable applications. It replaces older discrete amplifier solutions by integrating protection and noise suppression features directly onto the silicon die.

Audio Amplifiers Replacement Considerations

Consult manufacturer documentation for direct pin-compatible alternatives. Verify electrical parameters such as output power and supply voltage ranges match system requirements before substitution.
