NTP-8918

NEOFIDELITY NTP8918 High Performance, High Fidelity Power Driver Integrated Full Digital Audio Amplifier Datasheet ver. 1.0 2020 02 28 NEOFIDELITY, INC. NTP8918 Power Driver Integrated Full Digital Audio Amplifier General Description The NTP8918 is a single chip full digital audio amplifier including power stage for stereo amplifier system. The NTP8918 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 NTP8918 receives digital serial audio data with sampling frequencies of 32kHz, 44.1kHz, 48kHz, and 96kHz. It delivers 2 x 15 watts in stereo mode without heat sink. The NTP8918 has a mixer and Bi-Quad filters which can be used to implement the essential audio signal processing functions such as loudness control, compensation of a loud speaker response and parametric equalization. All the functions of the NTP8918 can be controlled by internal register values via I2C host interface bus.
