It is designed to maximize performance for mobile phone applications. 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 1.4W of continuous output power with less than 1% THD+N driving a 8Ω load from a 5V supply. The ISL99201 features a high-efficiency, low-noise modulation scheme. It operates with 86% efficiency at 400mW into 8Ω and has a signal-to-noise ratio (SNR) that is better than 95dB. The ISL99201 has a micro-power shutdown mode with a typical shutdown current of 200nA. Shutdown is enabled by applying a logic low to the SD pin. The architecture of the device...
