SAMP-200 HIFI Dual Core TPA3255 Stereo Amplifier Board 2 Channel 600W+600W Class D Digital Power Amplifier TL072 OP AMP 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._x000D_ 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)._x000D_ 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._x000D_ _x000D_ 1. Using 2 American TI-TPA3255 power amplifier modules, the output power separation is much better than that of a single chip._x000D_ 2. The front-end differential input circuit adopts boost technology, which makes the listening experience more dynamic than the official single 12V line._x000D_ 3. Fully shielded, low-loss sealed inductors, imported filter capacitors, no pressure at 55V_x000D_ Output power: 600W+600W/2 ohms 315W+315W/4 ohms 200W+200W/8 ohms Frequency response: 20HZ-30KHZ_x000D_ THD+N: 0.006% at 1W/4; Less than 0.01% at clipping Power supply voltage: positive 19V to positive 52V_x000D_ 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 will be reduced accordingly._x000D_ Colour:As Shown_x000D_ Material:abs_x000D_ Size:PCB Size:138x128MM_x000D_ _x000D_ Package Contents:_x000D_ 1 * Digital power amplifier_x000D_ _x000D_ Only the above package content, other products are not included._x000D_ Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
