Digital power amplifier is an audio power amplifier with the characteristics of low distortion, low noise, and large dynamic range; the NTP series of professional power amplifiers of South Korea's Naifu, represented by Gongcai.com, is a new milestone in ClassD power amplifiers.
NTP8835 is a high-performance, high-fidelity power driver integrated all-digital audio amplifier, operating voltage range: 7V ~ 28V; including 2 CH stereo (30W x 2 BTL @24V, 6Ω) and 2.1CH (10W x 2 + 30W @24V , 6Ω) has the advantages of high reliability, sufficient power, outstanding tone, and strong adaptability.
Korean NF's digital power amplifier has specialized noise reduction technology that can deal with noise caused by ripples on the power supply; it is specially designed for power amplification technology under low impedance and high current operation, giving it an efficiency of more than 95% and excellent stability. ; Can adapt to harsh environments and provide continuous surging power for the amplifier.
NTP8835 also has functions such as 3D surround, NS noise reduction algorithm, APEQ function adjustment, etc., which greatly enhances and optimizes the sound output effect; it also adds the function of ASRC (asynchronous sampling rate conversion), so that the sampling frequency input to IIS can be freely changed from 8kHz to 192kHz. No differential change.
1. Internal processor, NTP8835 processing frequency reaches 96K; has 60W maximum output power (THD <1%)
2. Adjustable equalizer (EQ). As we all know, the number of EQs in the power amplifier chip can determine the fineness of the product's sound quality adjustment; NTP8835 has up to 25-band PEQ + 5-band GEQ.
3. Dynamic power control (DRC) How DRC is done directly represents the performance of the power amplifier chip; NTP8835 is a 2-way DRC+POST DRC to maximize the cabinet sound effect.
In order to cope with the design of different circuit solutions, in addition to the conventional 2.0CH (BTL) and 0.1CH (PBTL) designs, the output design of 2.1CH (2xSE+1xBTL) can also be realized.
Starting from the 2.1CH audio system design, NTP8835 has:
◆One stereo output (2.0CH), one single channel output (0.1CH);
◆In terms of power, it can reach an output of 2*30W + 60W, with a total power of 120W; a very sufficient margin;
◆Less than 1% distortion, higher than 95db signal-to-noise ratio, no additional noise.
In addition, NTP8835 has different DSP sound effects: 3D surround sound based on patented technology, as if you were on the scene; ultra-low noise in DBTL mode; excellent heat dissipation performance with low output impedance;
The high frequency of NTP8835 has the advantages of excellent transient and large dynamics, fast and unambiguous response, high resolution, and clean and transparent sound; the low frequency also has no obvious sound coloration and has a better texture. At low and medium volumes, it can provide good control and outstanding transient performance.
South Korea's NF Company has been established for 20 years. It has been focusing on the independent research and development of digital audio chips for many years. It has a group of global high-end IC design experts and sound effect algorithm experts. Its product brand has a high reputation among the older generation of engineers. recognition, and has always been favored by local Korean companies Samsung and LG; nearly 80% of Samsung and LG's audio and video electronic products use Korean NF chip products and are sold around the world.
