Description

The NTP3000A 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.

A full digital audio amplifier is an amplifier that processes audio signals in the digital domain throughout the entire signal path, from input to output, without the need for analog-to-digital or digital-to-analog conversion.

Features

1. Stereo (30W ⅹ 2)

2. 2.1 channel (15Wⅹ2 + 30W)

3. Wide Supply Voltage Range (7V~30V)

4. Floating Point Operation
(1) 18 Programmable Biquad Filters
(2) Speaker Compensation
(3) DC cut, LPF, HPF
(4) Parametric Equalizer

5. PWM Output for External Subwoofer

6. 3D Surround

7. 7 Band Graphic Equalizer

8. 100 dB Dynamic Range

9. Adaptive Loudness Compensator based on Psycho Acoustics
