Maxim Integrated MAX9717AEUA+T Audio Amplifier

The MAX9717AEUA+T from Maxim Integrated is a high-quality, compact audio amplifier that is designed to deliver exceptional sound quality with minimal power consumption. This makes it an ideal choice for portable and space-constrained applications where audio performance and efficiency are crucial.

This audio amplifier is part of the MAX9717 series and comes in a small 8-pin µMAX package, making it easy to integrate into a variety of designs without taking up too much board space. The MAX9717AEUA+T operates over a wide supply voltage range from 2.7V to 5.5V, which allows for flexible usage in different system configurations, from battery-powered devices to those connected to a standard power supply.

One of the standout features of the MAX9717AEUA+T is its low 0.02% total harmonic distortion plus noise (THD+N) at 1kHz, which ensures high-fidelity audio output. The device also boasts a high 85dB power supply rejection ratio (PSRR) that minimizes noise and interference from fluctuating supply voltages, resulting in cleaner sound quality.

With its high efficiency of 90% under normal operating conditions, the MAX9717AEUA+T conserves power and extends battery life in portable applications. Additionally, the device includes a shutdown feature that reduces the supply current to less than 1µA, further conserving energy when the amplifier is not in use.

The MAX9717AEUA+T also features a click-and-pop suppression circuit that minimizes noise typically heard when the amplifier is turned on or off, providing a smoother user experience. Its built-in thermal overload protection ensures reliable operation by preventing the device from overheating during extended periods of use.

Overall, the MAX9717AEUA+T from Maxim Integrated is a versatile and efficient solution for designers looking to enhance audio performance in their products. Its combination of low distortion, high PSRR, and power-saving features make it a top choice for portable audio devices, mobile phones, laptops, and any other applications where quality audio amplification is desired in a compact form factor.
