Maxim Integrated Products' MAX98357 and MAX98358 digital input Class-D audio power amplifiers help designers achieve maximum efficiency with compact, cost-effective plug-and-play solutions. Although these amplifiers have very small form factors, they still provide 3.2W Class AB audio performance, resulting in higher audio quality, making them ideal for a variety of applications. Compared to typical analog amplifier designs, these amplifiers reduce the overall solution size by taking advantage of the company's clever pinout and reducing the number of components required. Since most users control their volume digitally upstream, these options allow customers to take advantage of the company's cost-effective WLP without the need for expensive VIA. For higher audio quality, they provide digital inputs to improve noise immunity and higher jitter tolerance. They also have excellent EMI performance and allow the use of longer traces to the speaker without additional external filtering. In addition, they provide the industry's highest Class D efficiency.
