GENERAL DESCRIPTION
The SSM2302 is a fully integrated, high efficiency, Class-D stereo audio amplifier. It 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 5.0 V supply. It is capable of delivering 1.4 W of continuous output power with less than 1% THD + N driving an 8 Ω load from a 5.0 V supply.
