Power Driver Integrated Full Digital Audio Amplifier
NTP8835
General Description
The NTP8835 is a single chip full digital audio amplifier including power stages for stereo amplifier systems. NTP8835 is integrated with versatile digital audio signal processing functions, high-performance, high-fidelity fully digital PWM modulator and two high-power full-bridge MOSFET power stages. The NTP8835 receives digital serial audio data with sampling frequencies from 8kHz through 192kHz. It delivers 2 x 30 watts in the stereo mode with a heat sink. The NTP8835 has a mixer and Bi-Quad filters which can be used to implement essential audio signal processing functions like compensation of a loud speaker response and parametric equalization. All the functions of the NTP8835 can be controlled by internal register values via I2C host interface bus.
