Description
This technology allows the device to maintain low distortion throughout the o frequency band while exhibiting good sound quality. The device operates in AD mode. When THD is 10%, it can drive up to two 315W / 4R loads and two 150W (unclipped power) / 8R loads, and has a 2 VRMS analog input interface to support high-performance DAC (Eg TI’s PCM5242) seamless connection. In addition to excellent o performance, the TPA3255 also has the advantages of high power efficiency and ultra-low power level idle loss (less than 2.5W)
Features
1. Adopt imported TPA3255 chip
2. The main filter electrolytic capacitor adopts a capacity of 470UF / 50V * 4, with strong and continuous power support.
3. The resistor uses high-precision chip resistors to ensure a good signal-to-noise ratio.
4. Adopt special inductance for o to ensure the sound is crisp and powerful.
5. PCB adopts 1.6mm thick double-sided board, 2.0 ounce copper thickness, full tin-spraying process, good passing performance of large and small current.
