FEATURE

  • Patented technology (EDMA) to reduce the internal Rdson and heat loss, increase the output power

    Po=3.5 W (VDD=5.0V, RL=4Ω, THD+N=10%)

    Po=5.5 W (VDD=5.0V, RL=2Ω, THD+N=10%)

  • Excellent EMI Suppression Performance

    a) Using Patented technology (AROC, Active edge Ringing and Overshoot Control circuitry)

    b) The emission level is highly lower than FCC Part15 Class B standard

    c) Without interference to FM radio, CMMB, GSM, CDMA, Bluetooth and any other sensitive modules with different bands;

    d) The difficulty of system design is reduced

  • THD+N=0.05% (RL=4Ω, PO=1W, f=1kHz)

  • Low noise, High SNR

  • Anti-Clipping Function (ACF)

  • Excellent Click-Pop Noise reduction function

  • Low Shutdown Current, 0.01µA

  • Filter-less Modulation, Eliminating Output Filter
