Maxim Integrated MAX9713ETJ+ Audio Amplifier

The MAX9713ETJ+ is a high-quality, feature-rich audio amplifier integrated circuit designed by Maxim Integrated, a renowned leader in the development of innovative analog and mixed-signal products. This particular component is well-suited for a variety of audio applications, from portable devices to home entertainment systems, offering a blend of power efficiency and audio performance that is hard to match.

The MAX9713ETJ+ is a Class D amplifier, which means it operates with high efficiency, converting more of the input power into audio output and less into heat. This not only saves energy but also minimizes the need for bulky heat sinks, allowing for more compact and portable designs. With its ability to deliver up to 2.4W per channel into a 4Ω load, this amplifier can power a wide range of speakers, providing clear and robust sound quality.

One of the standout features of the MAX9713ETJ+ is its integrated click-and-pop suppression. This function ensures that the power-up and power-down transients are minimized, preventing those unpleasant noises that can sometimes occur when turning audio equipment on or off. This feature is particularly important in consumer electronics, where user experience is paramount.

The MAX9713ETJ+ also offers flexibility in terms of input configurations. It can accept both differential and single-ended inputs, making it adaptable to different signal sources. This flexibility, combined with a low 0.02% THD+N (Total Harmonic Distortion plus Noise) and a PSRR (Power Supply Rejection Ratio) of 77dB at 217Hz, ensures that the audio output is crisp and clear, with minimal interference from power supply fluctuations.

Furthermore, the device is equipped with comprehensive protection features, including over-temperature protection, under-voltage lockout, and DC output protection. These features safeguard the amplifier and connected components from potential damage, ensuring reliability and longevity.

To accommodate a variety of design needs, the MAX9713ETJ+ is available in a 32-pin TQFN (Thin Quad Flat No-lead) package, which is not only space-saving but also conducive to efficient thermal management. Whether for portable audio devices, LCD TVs, or desktop speakers, the MAX9713ETJ+ from Maxim Integrated stands out as a superior audio amplification solution.
