www.DataSheet4U.com NCP9004 2.65 W Filterless Class D Audio Power Amplifier The NCP9004 is a cost effective mono Class D audio power amplifier capable of delivering 2.65 W of continuous average power to 4.0 W from a 5.0 V supply in a Bridge Tied Load (BTL) configuration.

Under the same conditions, the output power stage can provide 1.4 W to a 8.0 W BTL load with less than 1% THD+N.

For cellular handsets or PDAs it offers space and cost savings because no output filter is
