NCP2830
NCP2830 is Class D Audio Amplifier manufactured by onsemi.
NCP2830 1W Constant Filterless Class-D Audio Amplifier
NCP2830 is a cost effective mono audio power amplifier designed for portable munication device applications such as mobile phones. Due to its integrated charge pump structure, this part is capable of delivering 1 W of continuous average power to an 8.0 W Bridge Tied Load no matter the voltage provided by a lithium/Ion battery. NCP2830 is a preferred solution for long playback audio with minimum space required. Added to a fast start- up time of 200 ms and a
- 88d B PSRR, the NCP2830 audio power amplifier is specifically designed to provide high quality and level output power from low supply voltage, requiring very few external ponents.
