BRZHIFI TPA3255 300W+300W HiFi Bluetooth Amplifier Board Power Amp Board BT5.0 for LDAC & APTX HD

BRZHIFI TPA3255 300W+300W HiFi Bluetooth Amplifier Board Power Amp Board BT5.0 for LDAC & APTX HD

Description:
The product is designed for the most picky and HiFi audiophiles. It integrates the current TPA3255 power module with very low distortion and the Bluetooth decoding module QCC5125 supporting for LDAC and APTX. It also integrates PCM5102A high-end decoding chip. More quality components are used. As a result, the low-frequency sound is rich, the vocals are warm, and the high-frequency penetration is excellent. It is easy to use with treble and bass knobs. The price of this product is relatively high, because QCC5125 Bluetooth chip is used, and it also comes with independent decoding. Expensive black crystal common mode inductors are used as output inductors.

TPA3255 is a high-performance Class D power amplifier chip. It has a circuitry with Class D efficiency and is capable of delivering truly high-end sound quality. The device features an advanced integrated feedback design and a proprietary high-speed gate driver error correction feature (Ultra HD for PurePath). This technology allows the device to maintain ultra-low distortion across the entire audio frequency band while delivering sound quality. In AD mode, the device can drive up to two 315W/4R loads and two 150W (unclipped)/8R loads at 10% THD, and features a 2 VRMS analog input interface. It enables seamless connectivity to high-performance DACs such as PCM5242 for TI. In addition to excellent audio performance, the TPA3255 combines high power efficiency with ultra-low power level idle losses (less than 2.5W). This can be achieved with 85mR MOSFETs as well as an optimized gate driver scheme. Compared with traditional discrete implementations, this scheme can significantly reduce idle losses.
