Speaker audio power amplifier IC is commonly known as "amplifier" and also called audio power amplifier IC; it is an indispensable part of all kinds of audio equipment. Its main function is to amplify the weak signal input from the audio source equipment and generate a large enough current to drive the speaker. Perform sound playback.
Nowadays, with the popularity of artificial interaction and smart home, audio power amplifier chips are also increasing in sales of audio smart terminals represented by smart speakers and smart homes. The demand for audio power amplifier chips continues to grow; and a good audio power amplifier IC determines the sound quality of the speaker.
The Korean NF-digital power amplifier chip NTP8928, represented by Gongcai.com, is a multi-functional digital audio signal processing function, high performance, high fidelity digital PWM modulator and two high-power full-bridge MOSFET audio power amplifiers.
Using QFN6 x 6mm package; supports 2-channel stereo (20W x 2 BTL) operating power supply voltage range (5V ~ 28V) built-in DSP; 8 ohm speaker output efficiency is more than 90% ; 2*16-segment adjustable PEQ , truly improving sound quality
Provides 2 x 20 stereo modes without radiators, which can be used to implement functions such as intrinsic audio signal processing, volume control, compensated volume speaker response and parametric equalization;
Highlights and advantages of Korea Naif-NTP8928:
1. 3D surround sound based on patented technology, like being on the scene; low output impedance and good heat dissipation performance.
2. The proprietary master clock design ensures accurate processing of various digital signals, and the sound quality far exceeds that of CDs. It upconverts, digitally filters and noise-shapes low-bit data to full 32-bit data, resulting in extraordinary dynamic range and significantly better low-level resolution. Make your digital audio tracks sound better than ever.
3. APEQ patented technology, when the frequency band is limited, other frequency bands can be independently improved to give full play to the maximum performance of the speaker;
4. Multi-band intelligent equalizer, all products in the line have more settable PEQ points than similar products.
5. The entire series of power amplifiers has I2S and analog outputs, making it easier to expand application circuits; in order to eliminate the noise threat in today's high-speed board systems, NTP8928 has a fault elimination filter for the I2C port, and has an automatic deletion function when the transmission line fails.
6. It has 24Bit, 96KHz high-quality audio data processing and supports Hi-Res audio system. Other brand power amplifier products basically only have 48K data processing capabilities.
