NCP2823 Series
High Efficiency 3W
Filterless Class D Audio
Amplifier
The NCP2823A/B are cost effective mono audio power amplifiers designed for portable electronic devices. NCP2823A is optimized for 8 W operation and NCP2823B can operate with speaker impedance down to 4.0 W. For Instance, NCP2823B is capable of delivering 3 W of continuous average power to a 4.0 W 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 W 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.
