Product Specification
General Description：
The NTP8849 is a single chip full digital closed-loop audio amplifier including feedback power stage for stereo amplifier system.
The full digital closed-loop topology in power stage provides the elaborated system stability of output power even in the condition of PVDD in fluctuations.Also, NTP8849 is integrated with versatile digital audio signal processing functions, high-performance, high-fidelity fully digital PWM modulator and high-power full-bridge MOSFET power stages.
The NTP8849 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 NTP8849 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 NTP8849 can be controlled by internal register values via I2C host interface bus.
