EVAL-SSM2375Z

The EVAL-SSM2375Z is an evaluation board for SSM2375 filterless class D audio amplifier. The SSM2375 is a fully integrated, high efficiency, Class D audio amplifier. It is designed to maximize performance for mobile phone applications. The SSM2375 evaluation board carries a complete application circuit for driving a loudspeaker. The application circuit requires a minimum of external components and operates from a single 2.5V to 5.5V supply. It is capable of delivering 3W of continuous output power with less than 1% THD + N driving a 3R load from a 5V supply. Spread spectrum pulse density modulation (PDM) is used to provide lower EMI radiated emissions compared with other Class D architectures. The SSM2375 includes an optional modulation select pin that enables a low EMI mode, which significantly reduces the radiated emissions at the Class D outputs, particularly above 100MHz.
