Maxim Integrated MAX9730ET1+T Mono 2.5W Class AB Audio Amplifier

The MAX9730ET1+T from Maxim Integrated is a high-quality, mono, 2.5-watt Class AB audio amplifier designed to provide a blend of power efficiency and audio performance. This audio amplifier is an ideal solution for portable devices where high-quality audio and efficient power consumption are essential.

The MAX9730ET1+T features a low 0.02% THD+N (Total Harmonic Distortion plus Noise) at 1kHz, which ensures that the audio output remains crystal clear even at higher volumes. Its high PSRR (Power Supply Rejection Ratio) of 70dB at 217Hz minimizes noise and interference from fluctuating power supplies, making it perfect for battery-operated devices such as smartphones, tablets, and portable speakers.

This audio amplifier operates over a wide 2.7V to 5.5V supply voltage range, allowing it to be used in a variety of applications without the need for additional power regulation. The MAX9730ET1+T also includes built-in thermal overload protection that guards the device against damage from overheating, ensuring reliability and longevity.

One of the key features of the MAX9730ET1+T is its differential inputs, which reduce common-mode noise and improve sound quality. Additionally, it offers a low quiescent current of only 4mA, which helps to prolong battery life in portable applications. The device is also equipped with a shutdown mode that further reduces power consumption when not in use.

The MAX9730ET1+T comes in a compact 20-pin TQFN package with an exposed pad, making it easy to integrate into space-constrained designs without compromising on audio performance. Its surface-mount technology (SMT) design allows for efficient assembly in automated manufacturing processes.

Whether you're designing a portable media player, a handheld gaming device, or any other application requiring high-quality audio amplification with minimal power draw, the MAX9730ET1+T from Maxim Integrated offers the perfect combination of features to meet your needs.
