Maxim Integrated's MAX9716ETA+T Audio Amplifier

The MAX9716ETA+T from Maxim Integrated is a compact, high-efficiency audio amplifier designed to provide a robust audio solution for portable and space-constrained applications. This Class D amplifier is capable of delivering high-quality sound with minimal power loss, making it an ideal choice for battery-powered devices such as mobile phones, tablets, and portable media players.

One of the key features of the MAX9716ETA+T is its mono 1.4W BTL output, which operates at a 5V supply voltage, ensuring loud and clear sound reproduction. The device offers a high PSRR (Power Supply Rejection Ratio), which reduces the need for a regulated power supply and simplifies system design. Furthermore, its 92% efficiency at 1.4W into 8Ω minimizes heat generation, thereby enhancing the overall reliability and lifespan of the product.

The MAX9716ETA+T supports a wide range of input voltages, from 2.7V up to 5.5V, providing flexibility in various power environments. It also features a low 0.01% THD+N (Total Harmonic Distortion plus Noise) at 1kHz, which guarantees the delivery of high-fidelity audio output. The built-in click-and-pop suppression circuitry ensures smooth and noise-free power cycling, which is critical for consumer satisfaction.

Designed with space-saving considerations in mind, the MAX9716ETA+T comes in a tiny 8-pin TDFN (Thin Dual Flat No-Lead) package, which is optimal for portable applications where PCB real estate is at a premium. Additionally, the amplifier is fully specified over the extended -40°C to +85°C temperature range, making it suitable for use in a variety of operating environments.

For designers and engineers looking for a high-quality audio amplification solution, the MAX9716ETA+T provides a combination of performance, efficiency, and compactness. Its ease of integration and exceptional audio characteristics make it an excellent choice for the next generation of portable audio devices.

Maxim Integrated's commitment to quality ensures that the MAX9716ETA+T meets the stringent standards required for consumer electronics, offering both reliability and superior audio performance in a miniature package.
