Maxim Integrated MAX98306ETD+T Class D Amplifier

The MAX98306ETD+T from Maxim Integrated is a high-efficiency, Class D audio amplifier that offers superior audio performance in a compact package. This powerful audio solution is designed to deliver up to 3.7W of continuous output power into a 3Ω load or 3.2W into a 4Ω load, making it an ideal choice for portable and space-constrained applications where high-quality audio is required.

With its wide supply voltage range of 2.7V to 5.5V, the MAX98306ETD+T can be powered by a variety of sources, including single-cell lithium-ion batteries, making it highly versatile for use in a range of consumer electronics such as mobile phones, tablets, laptops, as well as portable speakers and other battery-operated audio devices.

The amplifier is equipped with Maxim's patented spread-spectrum modulation technology, which reduces electromagnetic interference (EMI), allowing the MAX98306ETD+T to be used in RF-sensitive environments without compromising audio performance or power efficiency. This feature is particularly beneficial for devices that need to comply with strict EMI/EMC regulations.

Furthermore, the MAX98306ETD+T boasts a high 92% efficiency, which not only conserves power but also minimizes the need for bulky heatsinks, keeping the overall design slim and lightweight. Its filterless architecture eliminates the need for external output filters, further reducing component count and saving on board space.

Designed with simplicity in mind, the MAX98306ETD+T requires minimal external components for operation, and its built-in click-and-pop suppression ensures smooth turn-on and turn-off transitions, preventing unwanted noises that can detract from the user experience. The device also features comprehensive protection against overcurrent, overheating, and undervoltage conditions, ensuring reliable operation and longevity.

Available in a compact, thermally-efficient 16-pin TQFN package, the MAX98306ETD+T is a robust audio amplification solution that combines high-quality sound with ease of integration, making it an excellent choice for designers looking to enhance the audio experience in their next-generation consumer electronic products.
