NCP2890, NCV2890
1.0 Watt Audio Power Amplifier
The NCP2890 is an audio power amplifier designed for portable communication device applications such as mobile phone applications. The NCP2890 is capable of delivering 1.0 W of continuous average power to an 8.0 W BTL load from a 5.0 V power supply, and 320 mW to a 4.0 W BTL load from a 2.6 V power supply.
The NCP2890 provides high quality audio while requiring few external components and minimal power consumption. It features a low−power consumption shutdown mode, which is achieved by driving the SHUTDOWN pin with logic low.
The NCP2890 contains circuitry to prevent from “pop and click” noise that would otherwise occur during turn−on and turn−off transitions.
