Maxim Integrated MAX98311EWL+T Mono Class D Amplifier

The MAX98311EWL+T from Maxim Integrated is a high-efficiency, mono Class D audio power amplifier that stands out for its compact size and impressive audio performance. Designed with portability in mind, this amplifier is an excellent choice for space-constrained applications such as mobile devices, portable media players, and other handheld electronics.

One of the key features of the MAX98311EWL+T is its DirectDrive® technology, which eliminates the need for an external DC-blocking capacitor. This not only saves on additional component costs but also reduces the overall footprint of the audio system. The amplifier is capable of delivering up to 3.2W of continuous output power into a 4Ω load with less than 1% THD+N, ensuring clear and powerful sound reproduction.

The device operates from a single 2.5V to 5.5V supply, making it versatile for various power scenarios. Its high 92% efficiency reduces power consumption, which is crucial for battery-powered devices, extending their usage time. Additionally, the MAX98311EWL+T features a low 1.6mA quiescent current, further conserving power when the device is in standby mode.

Integrating comprehensive protection features, the MAX98311EWL+T safeguards against damage from overcurrent events, thermal overload, and undervoltage conditions. These protective measures ensure long-term reliability and stability of the amplifier in all operating conditions.

The amplifier comes in a tiny 9-bump WLP (Wafer-Level Package) with a 1.345mm x 1.345mm footprint, which is highly beneficial for designs where PCB space is at a premium. Its surface-mount package is suitable for automated assembly processes, streamlining the manufacturing of consumer electronics.

Overall, the Maxim Integrated MAX98311EWL+T is a robust audio solution that combines miniaturization with performance, making it an ideal choice for designers looking to enhance the audio experience in their next-generation portable devices.
