Bảng mạch khuếch đại âm thanh kỹ thuật số TPA3255 2.0 DC24-48v

[2.10]Amplifier Board TPA3255 2.0 Digital Amplifier Board DC24-48v Strong Power Features: 1. The computing end adopts replaceable dip-8 op amp*2, and buyers can upgrade the computing model independently. This product uses 2 ti ne5532p high-performance audio operational amplifier 2. The main electrolytic capacitor filter adopts Nichicon 2200uf/63v*2 capacity, 6 Nichicon fw series 10uf golden audio input coupling capacitors. Other filter capacitors use nichicon series. 3. Class D digital audio amplifier adopts phase model 7W14A inductor to ensure clear and powerful sound. 4. The device uses advanced integrated feedback design and proprietary high-speed port driver (purepath ultra-high-definition) error correction function. 5. High power efficiency and ultra-low power level idle loss (less than 2.5w). This can be achieved by 85mr mosfet and optimized gate driver scheme. Description: The digital amplifier board uses Sagamo 7W14A inductor to ensure clear and powerful sound.
