Maxim Integrated MAX9701ETG+ Audio Amplifier

The MAX9701ETG+ is a high-efficiency, Class D audio amplifier from Maxim Integrated, designed to deliver superior audio performance for a wide range of consumer electronics. This compact, yet powerful, audio solution is ideal for applications where space is at a premium and power efficiency is crucial, such as portable media players, laptops, and mobile devices.

Equipped with a 2.4V to 5.5V supply voltage range, the MAX9701ETG+ is capable of driving a 4Ω load with up to 1.4W of output power, ensuring loud and clear sound reproduction. The amplifier operates over the -40°C to +85°C temperature range, making it suitable for use in a variety of environments.

One of the key features of the MAX9701ETG+ is its high efficiency, which not only conserves power but also minimizes heat generation. This is particularly important in portable applications where battery life and device longevity are paramount. Additionally, the device includes a 92% efficiency rate (at 1.4W into 8Ω), which further underscores its power-saving capabilities.

The MAX9701ETG+ also boasts a low 0.02% THD+N (Total Harmonic Distortion plus Noise) at 1kHz, ensuring high-fidelity audio playback. Its filterless modulation allows the device to pass audio signals without the need for bulky external filters, simplifying the design and reducing the overall component count. This makes the MAX9701ETG+ an excellent choice for space-constrained applications.

For design flexibility, the MAX9701ETG+ features fully differential inputs, which help to reduce common-mode noise and improve sound quality. The device also includes comprehensive built-in protections such as over-current protection, thermal shutdown, and under-voltage lockout, ensuring reliable operation and safeguarding against potential damage caused by abnormal operating conditions.

Available in a compact 24-pin TQFN package, the MAX9701ETG+ is an optimal audio amplification solution for designers looking to enhance the audio experience in their products without compromising on space or efficiency. With its high-quality audio output, energy-saving design, and robust protection features, the MAX9701ETG+ from Maxim Integrated stands out as a top choice for next-generation audio applications.
