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. With more than 90% efficiency and very low shutdown

current, it increases the lifetime of your battery and drastically lowers

the junction temperature.

NCP2823 processes analog inputs with a pulse width modulation

technique that lowers output noise and THD. The device allows

independent gain while summing signals from various audio sources.

Thus, in cellular handsets, the earpiece, the loudspeaker and even

melody ringer can be driven with a single NCP2823. Due to its low

26 mV noise floor, A−weighted, clean listening is guaranteed no matter

the load sensitivity.
