EVAL-SSM2356Z(RevA) Datasheet PDF - Analog Devices

GENERAL DESCRIPTION
The SSM2356 is a fully integrated, high efficiency, stereo Class-D 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 5.5 V supply. It is capable of delivering 2 × 2W of continuous output power with <1% THD + N driving a 4 Ω load from a 5.0 V supply.
