Product Introduction:

TPA3255 is a high-performance Class D power amplifier chip, which has Class D efficiency and can bring true high-end sound quality circuits. The device has advanced integrated feedback design and proprietary high-speed gate driver error correction function. This technology enables the device to maintain ultra-low distortion throughout the entire audio frequency band while showcasing sound quality. This device operates in AD mode and can drive up to 2 315W/4R loads and 2 150W (unshipped power)/8R loads at a THD of 1.5%. It also has a 2VRMS analog input interface and supports seamless connection with high-performance DACs (such as TI's PCM5242).

In addition to excellent audio performance, TPA3255 also has two major advantages: high power efficiency and ultra-low power level idle loss (less than 2.5W). This can be achieved through an 85mR MOSFET and an optimized gate driver scheme. This scheme can significantly reduce idle loss compared to traditional discrete implementation schemes.

This product adopts excellent circuit design and high-quality components, ensuring its performance and stable operation at DC 52V. It also passed the 60V high-voltage test in laboratory testing. In order to ensure sound quality, TPA3255 adopts a differential input structure, and the operational amplifier adopts a TL072 operational amplifier with field effect input. The sound quality is warm, and the input uses HIFI tantalum capacitors, which are delicate and natural. The main filter is made of Japanese chemical or Nikon capacitors with a voltage resistance of up to 63V, ensuring safety. The output adopts a lossless red ring inductor and a CBB high current capacitor. An additional 5V terminal has been added to the output, which can be used for Bluetooth and playback
