1. Using TPA3250
2. The main circuit of the electrolytic capacitor signal adopts a chip electrolytic capacitor with a capacity of 4*220UF, which ensures a strong and continuous .
3. The resistors use high-precision chip resistors to a good signal-to-noise of the whole machine.
4. The PCB adopts 1.6m thick double-sided sheet, 2.0 copper thickness, and the whole process of spraying tin to good passing performance of and small currents. Top- PCB quality.
5. Fully shielded high-current inductors are used to clear and powerful sound. The TPA3250 device is a high-performance Class-D power amplifier that delivers true high-quality sound with Class-D efficiency. The device features an advanced integrated feedback design and proprietary high-speed gate driver error correction (Purepath Ultra-HD). This technology enables ultra-low distortion and superior audio quality in the audio frequency band. The device operates from a 32V supply Power supply, can up to 2W*130W drive to 4ohm load, or 2W*70W continuous drive to 8ohm load, and has 2 VRMS analog input interface, which can be seamlessly matched with high-performance DACs such as TI PCM5242. Audio performance, the TPA3250 also achieves high power efficiency and power no-load power dissipation 1 W. This is achieved by using 60 mohm MOSFETs and an optimized gate driver scheme with much lower no-load losses than typical discrete devices.
