DLHiFi TPA3255 2.0 DC24-40V 300W + 300W Class D Digital Strong High Power Amplifier Board

The TPA3255 is a high-performance Class-D power amplifier with Class-D efficiency for true high-end sound quality. The device features an advanced integrated feedback design and proprietary high-speed gate driver error correction (PurePath Ultra HD). This technology enables the device to maintain ultra-low distortion across the entire audio frequency band while exhibiting flawless sound quality.
The device works in AD mode. When the THD is 10%, it can drive up to 2 315W/4R loads and 2 150W (no interference power)/8R loads, and has a 2 VRMS analog input interface that supports seamless connection of high-performance DACs (such as TI's PCM5242) connect.
In addition to excellent audio performance, the TPA3255 has two main advantages: high power efficiency and ultra-low power stage idle losses (less than 2.5W). This can be achieved with an 85mR MOSFET and an optimized gate driver scheme. This solution can significantly reduce idle losses compared to traditional discrete implementations.
Product Details: 1. Use the TPA3255; 2. The computing side uses a replaceable DIP-8 op amp x 2, and the buyer can upgrade the computing model independently. This product uses 2 TI high-performance audio operational amplifiers NE5532P
The main filter electrolytic capacitor adopts Nichicon capacity 2200UF/63V x 2, 6 Nichicon FW series 25V 10UF golden audio input coupling capacitors. Other filter capacitors use the Nichicon series. Audio digital class D amplifier adopts 7W14A inductor to ensure clear and strong sound.
