Maxim Integrated MAX98304DEWL+T Class D Audio Amplifier

The Maxim Integrated MAX98304DEWL+T is a high-efficiency, mono Class D audio amplifier that is designed to deliver exceptional audio quality in a compact package. It is an ideal solution for portable and space-constrained applications, such as smartphones, tablets, laptops, and other consumer electronics that demand high-quality sound reproduction with minimal power consumption.

This audio amplifier features a single differential input that ensures compatibility with various audio sources. The MAX98304DEWL+T operates over a wide 2.5V to 5.5V supply voltage range, making it versatile for use in different system designs. The device can deliver up to 3.2W of continuous output power into a 4Ω load with less than 1% THD+N, ensuring loud and clear sound without distortion.

The MAX98304DEWL+T incorporates Maxim's proprietary Class DG modulation scheme, which dynamically adjusts the supply voltage in response to the input signal, reducing power consumption and extending battery life in portable applications. This feature, combined with high 92% efficiency, makes the MAX98304DEWL+T an energy-efficient choice for today's battery-operated devices.

Built-in features include comprehensive click-and-pop suppression that minimizes noise during turn-on and turn-off transitions, as well as thermal overload and short-circuit protection to ensure reliable operation under adverse conditions. The device also offers a low 1.6mA quiescent current, further contributing to its power-saving capabilities.

The MAX98304DEWL+T comes in a small, 9-pin WLP (Wafer-Level Package) that is just 1.345mm x 1.345mm in size, making it an excellent choice for designs where PCB real estate is at a premium. The compact form factor, combined with its high performance and integrated features, makes the MAX98304DEWL+T a leading solution for designers looking to enhance the audio experience in their next-generation electronic products.
