Maxim Integrated MAX9741ETN Class D Audio Amplifier

The MAX9741ETN from Maxim Integrated is a high-efficiency, Class D audio amplifier that is designed to deliver premium sound quality for a wide range of audio applications. This compact yet powerful device comes in a 56-pin TQFN (Thin Quad Flat No-lead) package, making it an ideal choice for space-constrained applications such as flat-panel televisions, portable speakers, and other consumer electronics where superior audio performance is desired.

The MAX9741ETN operates from a single 8V to 28V supply, providing a flexible power range to accommodate various design requirements. It is capable of delivering up to 2 x 25W into an 8Ω load or 1 x 50W into a 4Ω load, ensuring ample power for driving stereo speakers or a single subwoofer. Its high efficiency not only conserves power but also reduces the need for bulky heatsinks, thus contributing to a more streamlined and cost-effective product design.

One of the standout features of the MAX9741ETN is its integrated volume control, which allows for smooth and precise adjustment of the audio output level. Additionally, the amplifier boasts a low 0.04% THD+N (Total Harmonic Distortion plus Noise) at 1W, providing crystal-clear audio reproduction that is free from distortion even at high volumes.

For ease of integration into various systems, the MAX9741ETN includes a comprehensive set of protection features, such as over-current protection, thermal protection, and under-voltage lockout. These features ensure reliable operation and longevity of the amplifier by safeguarding it against potential damage from abnormal operating conditions.

The MAX9741ETN also offers a simple, pin-controlled interface for power and mute functions, allowing designers to easily implement basic user controls. With its excellent audio performance, robust protection features, and user-friendly interface, the MAX9741ETN from Maxim Integrated is a top choice for designers looking to enhance the audio experience in their next project.
