Features

* a low
* power consumption shutdown mode, which is achieved by driving the SHUTDOWN pin with logic low. The NCP2991 contains circuitry to prevent from “pop and click” noise that would otherwise occur during turn
* on and turn
* off transitions. It is a zero pop noise device when a s

Applications

* such as mobile phone applications. The NCP2991 is capable of delivering 1.35 W of continuous average power to an 8.0 W BTL load from a 5.0 V power supply, and 1.1 W to a 4.0 W BTL load from a 3.6 V power supply. The NCP2991 provides high quality audio while requiring few external components and mini
