The TPA3255 is a high-performance Class D power amplifier with Class D efficiency and 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 allows the device to maintain ultra-low distortion across the entire audio frequency band while delivering perfect sound quality. The device operates in AD mode with a maximum output of 600WX2/2R or 300WX2/4 ohm and 200WX2/8 ohm load and has a unique 2 VRMS analog input interface that supports seamless connection with high-performance DACs (such as TI's PCM5242). In addition to excellent audio performance, the TPA3255 combines high power efficiency with ultra-low power level idle losses (less than 2.5W). This is achieved with 85mR MOSFETs and an optimized gate driver scheme. This solution can significantly reduce idle losses compared to traditional discrete implementations. 1. Using 2 American TI-TPA3255 power amplifier modules, the output power separation is much that of a single chip. 2. The front-end differential input circuit adopts boost technology, which makes the listening experience more dynamic than the official single 12V line. 3. Fully shielded, low-loss sealed inductors, filter capacitors, no pressure at 55V Output power: 600W+600W/2 ohms 315W+315W/4 ohms 200W+200W/8 ohms Frequency response: 20HZ-30KHZ +N: 0.006% at 1W/4; Less than 0.01% at clipping Power supply voltage: positive 19V to positive 52V Note:The higher the input power supply, the greater the power supply current and the greater the output. The power test is measured at 50V power supply. If you switch to a 24V 36 low voltage power supply, the output power be reduced accordingly.
