Maxim Integrated MAX9720BEUE+T Audio Amplifier

The MAX9720BEUE+T from Maxim Integrated is a high-quality, stereo DirectDrive® headphone amplifier that offers an exceptional audio experience for a wide range of applications. Designed with the latest technology, this integrated circuit (IC) delivers superior sound quality without the need for bulky DC-blocking capacitors, ensuring a more compact and efficient design for portable audio devices.

With its DirectDrive architecture, the MAX9720BEUE+T eliminates the need for external capacitors by coupling the headphone return path to the ground, providing a ground-referenced output that reduces component count and saves board space. This feature makes it an ideal solution for space-constrained applications such as mobile phones, portable media players, and laptop computers.

The device operates from a single 2.7V to 5.5V supply, making it versatile for use in various systems with differing power requirements. The MAX9720BEUE+T is capable of delivering up to 130mW per channel into a 16Ω load, ensuring powerful and clear audio output for a rich listening experience. Additionally, it boasts a low 0.004% total harmonic distortion plus noise (THD+N) at 1kHz, which translates into pristine sound quality with minimal distortion.

This amplifier also features a high 100dB power-supply rejection ratio (PSRR), which minimizes noise and interference from fluctuating power supplies, ensuring a stable and consistent audio performance. The MAX9720BEUE+T comes with built-in thermal overload protection and a low-power shutdown mode, providing both safety and energy efficiency.

The MAX9720BEUE+T is available in a compact 16-pin TSSOP package, which is RoHS compliant and designed for easy integration into various electronic assemblies. Its temperature range of -40°C to +85°C ensures reliable operation in a wide range of environmental conditions.

For designers and audio enthusiasts looking for a high-performance, space-saving headphone amplifier, the MAX9720BEUE+T from Maxim Integrated is an excellent choice that combines quality, efficiency, and reliability in a single compact component.
