Power Driver Integrated Full Digital Audio Amplifier
General Description
The NTP8818 is a single chip full digital audio amplifier including power stage for stereo amplifier system. NTP8818 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 NTP8818 receives digital serial audio data with sampling frequencies of 32kHz, 44.1kHz, 48kHz, and 96kHz. It delivers 2 x 20 watts in stereo mode without heat sink. The NTP8818 has a mixer and Bi-Quad filters which can be used to implement the essential audio signal processing functions like loudness control, compensation of a loud speaker response and parametric equalization. All the functions of the NTP8818 can be controlled by internal register values via I2C host interface bus.
