The SSM2301 is a single-chip, single-channel, Class-D audio amplifier. It is a fully integrated chip, which means that the application circuit requires a minimum of external components.
It comes with a differential mode input port and a high efficiency H-bridge at the output. When compared to a half-bridge output stage, a full H-bridge enables direct coupling of the audio power signal to the loudspeaker, doubling the output voltage swing and eliminating the need for a large output coupling capacitor.
The SSM2301 evaluation board carries a complete application circuit for driving one loudspeaker.
