產品總覽

The NCP2820MUTBG is a mono class-D Audio Power Amplifier capable of delivering 2.65W of continuous average power to 4R bridge tied load from a 5V supply. Under the same conditions, the output power stage can provide 1.4W to a 8R BTL load with less than 1% THD+N. For cellular handsets or PDAs, it offers space saving 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. The NCP2820 processes analog inputs with a pulse width modulation technique that lowers output noise and THD when compared to a conventional sigma-delta modulator. The device allows independent gain while summing signals from various audio sources. Thus, in cellular handsets, the earpiece, the loudspeaker and even the melody ringer can be driven with a single NCP2820.
  • Fully differential design
  • Eliminates two input coupling capacitors
  • Very fast turn on/off times with advanced rising and falling gain technique
  • External gain configuration capability
  • Internally generated 250kHz switching frequency
  • Pop and click noise protection circuitry
  • Optimized PWM output stage - Filterless capability
  • Efficiency up to 90%
  • High performance
  • Excellent PSRR (-65dB) - No need for voltage regulation
