1.TPA3255 is a high-performance Class D power amplifier chip, which has Class D efficiency and can bring true high-end sound quality circuits.
2. This product can maintain ultra-low distortion throughout the entire audio frequency band while showcasing sound quality.
4. TPA3255 adopts a differential input structure, and the operational amplifier adopts a TL072 operational amplifier with field effect input, providing warm sound quality. The input uses HIFI tantalum capacitors, which are delicate and natural.
5. The output adopts a lossless red ring inductor and a CBB high current capacitor, and an additional 5V terminal is added to the output, which can be used as a backup for external devices such as Bluetooth and players.
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).
Spare external equipment such as amplifiers.
