Product Overview NCP2823: Audio Power Amplifier, 3.0 W, Filterless, Class D For complete documentation, see the data sheet Product Description The NCP2823A/B are cost effective mono audio power amplifiers designed for portable electronic devices. NCP2823A is optimized for 8 Ω operation and NCP2823B can operate with speaker impedance down to 4.0 Ω.For Instance, NCP2823B is capable of delivering 3 W of continuous average power to a 4.0 Ω from a 5.0 V supply in a Bridge Tied Load (BTL) configuration. Under the same conditions, NCP2823A can provide 1.5 W to an 8.0 Ω BTL load with less than 10% THD+N. For cellular handsets or PDAs it offers space and cost savings because no output filter is required when using inductive transducers. With more than 90% efficiency and very low shutdown current, it increases the lifetime of your battery and drastically lowers the junction temperature.
