Audio TPA3255 2.0 Digital Amplifier Board DC24-48v Digital Amplifier Board

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.
