Maxim Integrated MAX4364ESA/V+ Audio Amplifier

The MAX4364ESA/V+ is a high-quality audio amplifier designed and manufactured by Maxim Integrated. This compact, efficient device is ideal for portable and space-constrained applications, where delivering clear and powerful audio performance is a must. The MAX4364ESA/V+ comes in a space-saving 8-pin SOIC package and operates over the extended temperature range of -40°C to +85°C, making it a versatile choice for a wide range of audio applications.

The amplifier is capable of delivering 1.4W continuous power into a 4Ω load with a 5V power supply, ensuring a robust audio output for its size. It also features a low 0.02% total harmonic distortion plus noise (THD+N) at 1kHz, which means that the audio output is not only strong but also clear and high-fidelity. This makes the MAX4364ESA/V+ suitable for applications where audio quality cannot be compromised.

One of the key attributes of the MAX4364ESA/V+ is its high power-supply rejection ratio (PSRR) of 85dB at 217Hz, which minimizes the amount of power supply noise that is transferred to the audio signal. This ensures that the amplifier can deliver a clean audio output even in environments with fluctuating power supplies.

Furthermore, the device includes a shutdown feature that reduces the supply current to only 0.1µA, allowing for increased power conservation when the amplifier is not in active use. This is particularly beneficial for battery-powered devices, where energy efficiency is critical.

The MAX4364ESA/V+ also boasts a click-and-pop suppression circuit that reduces the noise heard when the amplifier is turned on or off. This feature enhances the user experience by providing a smoother transition between operational states, without the common annoyance of audible pops.

In conclusion, the MAX4364ESA/V+ from Maxim Integrated is a powerful, high-fidelity audio amplifier that is perfectly suited for portable devices, multimedia applications, and any other system where space is at a premium but audio quality cannot be sacrificed. Its combination of power, clarity, and energy-saving features makes it an excellent choice for designers looking to enhance the audio capabilities of their products.
