NCP2811BMTTXG

Product Summary

The NCP2811BMTTXG is a dual audio power amplifier designed for portable communication device applications such as mobile phones. This part is capable of delivering 27 mW of continuous average power into a 16 Ω load from a 2.7 V power supply with a THD+N of 1%. Based on the power supply delivered to the device, an internal power management block generates a symmetrical positive and negative voltage. Thus, the internal amplifiers provide outputs referenced to Ground. In this True Ground configuration, the two external heavy coupling capacitors can be removed. The NCP2811BMTTXG offers significant space and cost savings compared to a typical stereo application. The applications of the NCP2811BMTTXG include Cellular Phones, MP3 Player, Personal Digital Assistant and Portable Media Player, Portable Devices.
