Maxim Integrated's MAX98400BETG+T Class D Audio Amplifier

The MAX98400BETG+T is a high-performance Class D audio amplifier from Maxim Integrated, designed to deliver exceptional sound quality with high efficiency. This integrated circuit is a perfect solution for space-constrained applications where top-notch audio performance and power efficiency are crucial. The MAX98400BETG+T stands out with its patented spread-spectrum modulation technology which minimizes EMI, making it ideal for a wide range of consumer electronics such as TVs, monitors, and portable speaker systems.

With its integrated stereo design, the MAX98400BETG+T can deliver up to 2 x 20W into a 4Ω load, and 2 x 10W into an 8Ω load, all from a 12V supply, ensuring powerful and clear audio output. The amplifier operates over a wide 10V to 28V supply voltage range, providing design flexibility for various power supply scenarios. Its high 92% efficiency reduces power consumption and heat generation, which is critical for maintaining the longevity and reliability of the device.

The device features a comprehensive set of protections, including overcurrent protection (OCP), undervoltage protection (UVP), and thermal shutdown, safeguarding the IC from potential damage during fault conditions. Additionally, the MAX98400BETG+T boasts a low 0.04% THD+N at 1W, ensuring high-fidelity audio reproduction that is virtually free from distortion.

For ease of integration, the MAX98400BETG+T is available in a compact, thermally efficient 24-pin TQFN package with an exposed pad. This small footprint allows for minimized PCB space usage, while the exposed pad design enhances thermal performance, ensuring the amplifier runs cooler during operation.

Maxim Integrated's commitment to providing advanced audio solutions is evident in the MAX98400BETG+T, making it an excellent choice for designers looking to enhance the audio experience in their products without compromising on space or power efficiency.
