Maxim Integrated's MAX9719AETE+T: High-Efficiency Audio Amplifier

The MAX9719AETE+T is a state-of-the-art audio amplifier from Maxim Integrated, designed to deliver high-quality sound with maximum efficiency. This component is part of Maxim's extensive range of audio solutions, tailored to meet the needs of a variety of applications, from portable devices to home entertainment systems.

Featuring a mono bridge-tied load (BTL) output, the MAX9719AETE+T can deliver up to 1.4W into an 8Ω load, or 1.8W into a 4Ω load, with a 5V power supply, making it an excellent choice for compact applications that require powerful audio output. The amplifier operates over a wide 2.7V to 5.5V supply voltage range, providing design flexibility for various system power requirements.

The MAX9719AETE+T offers a high 90% efficiency, which not only ensures minimal power loss but also reduces the heat generated during operation. This high efficiency makes it ideal for battery-powered devices, where extended battery life is crucial. Additionally, the device includes a low-power shutdown mode, further conserving energy when the amplifier is not in use.

Designed with a focus on sound quality, the MAX9719AETE+T features low 0.04% THD+N (Total Harmonic Distortion plus Noise) at 1kHz, which translates to clear and crisp audio output. The component also boasts a high 80dB PSRR (Power Supply Rejection Ratio) at 217Hz, which means it can suppress power supply noise and prevent it from affecting the audio signal.

For ease of integration into various designs, the MAX9719AETE+T comes in a compact 16-pin TQFN package with an exposed pad. It also includes comprehensive built-in protection features such as thermal overload protection and output short-circuit protection, ensuring long-term reliability and stability in operation.

Whether you are designing a portable speaker, a smartphone, or any other device where premium sound quality and power efficiency are paramount, the MAX9719AETE+T from Maxim Integrated is an outstanding audio amplifier solution that will meet and exceed your design specifications.
