SSM2301 Datasheet Filterless High Efficiency Mono 1.4 W Class-d Audio Amplifier

Manufacturer: Analog Devices

Overview: Filterless High Efficiency Mono 1.4 W Class-D Audio Amplifier SSM2301.

General Description

The SSM2301 is a fully integrated, high efficiency, Class-D audio amplifier 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.
