ISL99203 High Efficiency Audio Subsystem

ISL99203 High Efficiency Audio Subsystem The ISL99203 is a fully integrated high efficiency classD mono amplifier combined with a capfree headphone amplifier. It is designed to maximize performance for mobile phone applications while saving valuable board space. The application circuit requires a minimum requirement of external components and operates from a 2.4V to 5.5V input supply. It is capable of delivering 1.5W of continuous output power with less than 10% THD+N driving a 8 load from a 5V.

ISL99203 Features

* a high-efficiency, low-noise modulation scheme. It operates with 85% efficiency at 400mW into 8 from 5V supply and has a signal-to-noise ratio (SNR) that is greater than 95dB. The architecture of the device allows it to achieve very low level pop and click. This minimizes voltage glitches at the ou
