Analog DevicesEVAL-SSM2319ZIntegrierte Verstärkerschaltung, Entwicklungsplatinen und -kits

The SSM2319 is a fully integrated, single-chip, mono Class-D audio amplifier that is designed to maximize performance for mobile phone applications. The application circuit requires a minimum of external components and operates from a single 2.5 V to 5.5 V supply. It is capable of delivering 3 W of continuous output power with less than 1% THD + N driving a 3 Ω load from a single 5.0 V supply. The SSM2319 is equipped 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.
