["brand new and high quality\nFeature:\nTPA3251D2 is a high-performance class D power amplifier, which has class D efficiency and can bring true high-end sound quality. \nThe device features advanced integrated feedback design and proprietary high-speed gate driver error correction function. \nThis technology allows the device to maintain ultra-low distortion throughout the audio frequency band while exhibiting perfect sound quality. \nThe device can drive up to 2*175W / 4Ω loads or 2*220W / 3Ω loads, and has a 2 VRMS analog input interface that supports seamless connection with high-performance DACs (for example, TI's PCM5242). In addition to excellent audio performance, TPA3251D2 also has two major advantages: high power efficiency and ultra-low power level idle loss (below 1W). This can be achieved with a 60mΩ MOSFET and an optimized gate driver solution, which can significantly reduce idle losses compared to traditional discrete implementations.\n\nBasic performance parameters:\nThe total output power when the total harmonic distortion + noise (THD + N) is 10% .\n175W /4 ohm , Bridge Tied Load (BTL) stereo configuration .\n 220w /3 ohm , bridged load (BTL) stereo configuration .\n 350w /2 ohm , parallel bridge load (PBTL) mono configuration .\nThe total output power when THD＋N is 1%.\n140W /4 ohm , BTL stereo configuration .\n175w /3 ohm, BTL stereo configuration .\n285W /2 ohm, PBTL mono configuration .\nAdopt advanced integrated feedback design, with high-speed gate driver error correction function.\nSingle broadband up to 100kHz for high-frequency components of high-definition sources.\nUltra-low THD +N: 0.005% at 1W /4 ohm; <0.01% at clipping .\n60dB Power Supply Rejection Ratio (PSRR) (BTL, no input signal).\n<60uV (A-weighted) output noise .\n> 111dB (A-weighted) signal-to-noise ratio (SNR) .\n\nSpecifications:\nName: Amplifier Board\nModel: TPA3251D2\nWorking Voltage: DC24-36V \nMaterial: Metal\nSize: approx.15x9cm/5.91x3.54in\nColor: As pictures shown\nQuantity: 1 Pc\n\nNote:\nPlease allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.\nDue to the difference between different monitors, the picture may not reflect the actual color of the item.
