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 operates from a single 2.5 V to 5.5 V supply and is capable of delivering 2.8 W of continuous output power with less than 10% THD + N driving a 4 Ω load from a single 5.0 V 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 canceling of common-mode noise.
The SSM2305 evaluation board carries a complete application circuit for driving a loudspeaker.
