NCP2993 Audio Power Amplifier, 1.3 W, with Selectable Fast Turn-On Time The NCP2993 is an audio power amplifier designed for portable communication device applications such as mobile phone applications. The NCP2993 is capable of delivering 1.3 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 NCP2993 provides high quality audio while requiring few external components and minimal power consumption. It feat.

NCP2993 Features

* a low

* power consumption shutdown mode, which is achieved by driving the SHUTDOWN pin with logic low. The NCP2993 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
