NTP8818

NEOFIDELITY NTP8818 High Performance, High Fidelity Power Driver Integrated Full Digital Audio Amplifier Datasheet ver. 1.2 NEOFIDELITY, INC. NTP8818 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.
