Description :

Power Integrated Processor for Digital Amplifier NTP3000 NTP3000 1CHIP 2.1CHANNELFULLDIGITALAMPLIFIER Features Stereo (30W ⅹ 2) 2.1 channel (15Wⅹ2 + 30W) Wide Supply Voltage Range (7V~30V) Floating Point Operation 18 Programmable Biquad Filters Speaker Compensation DC cut, LPF, HPF Parametric Equalizer PWM Output for External Subwoofer 3D Surround 7 Band Graphic Equalizer 100 dB Dynamic Range Adaptive Loudness Compensator based on Psycho Acoustics Applications Plasma TV, LCD TV Docking Station Mini-Component Audio Description NTP3000 is a single chip full digital audio amplifier including power stage for stereo or 2.1 channel amplifier system. NTP3000 is integrated with versatile digital audio signal processing functions, high-fidelity fully digital PWM modulator and two high-power full bridge MOSFET stages. NTP3000 receives 2-channel serial audio data with sampling frequency from 8 kHz to 192 kHz. It delivers 2x30W in stereo mode or 2x15W + 1x30W in 2.1 channel mode without heat sink. Combining use of built-in mixer and biquad filters can make additional preprocessing like bass management, loudness control, loudspeaker response compensation and preset parametric equalizers possible. All the functions of NTP3000 are set by I2C register configuration.
