GENERAL DESCRIPTION
The SSM2375 is a fully integrated, high e ciency Class-D audio ampli er. It is designed to maximize performance for mobile phone applications. e 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 an 3 Ω load from a 5.0 V supply.
