The SSM2305-EVALZ is an evaluation board for Mono 2.8W class-D audio amplifier. The SSM2305 evaluation board carries a complete application circuit for driving a loudspeaker. The SSM2305 is a fully integrated, single chip, mono class-D audio amplifier that is designed to maximize performance for mobile phone applications. The application circuit is capable of delivering 2.8W of continuous output power with less than 10% THD + N driving a 4R load from a single 5V supply. The SSM2305 comes with a differential mode input port and a high efficiency, full H-bridge at the output that enables direct coupling of the audio power signal to the loudspeaker. The differential mode input stage allows for cancelling of common mode noise.
