Features:
Excellent Audio Performance: The TPA3255 is a high-performance Class D power amplifier chip with Class D efficiency. Its circuit delivers true high-end sound quality, maintaining ultra-low distortion across the entire audio frequency band while showcasing outstanding sound quality.
High Efficiency and Energy Saving: This product combines high power efficiency with ultra-low power stage idle loss (less than 2.5W). It is achieved through an 85mR MOSFET and an optimized gate driver scheme, significantly reducing idle losses compared to traditional discrete implementations.
Stable and Reliable Operation: The product adopts excellent circuit design and high-quality components, ensuring guaranteed performance. It can operate stably under 52V DC and has passed the 60V high-voltage test in the lab.
High-Quality Input Design: The TPA3255 features a differential input structure. The operational amplifier uses a field-effect input TL072 operational amplifier, delivering a warm sound quality. The input employs HiFi tantalum capacitors, resulting in a delicate and natural sound.
High-Quality Output Components: The output utilizes lossless red ring inductors and CBB high-current capacitors. An additional 5V terminal is provided at the output, which can serve as a spare power source for external devices such as Bluetooth devices and players.
Powerful Driving Capability: Operating in AD mode, at a THD of 1.5%, it can drive up to two 315W/4Ω loads and two 150W (unclipped power)/8Ω loads.
