Product introduction: TPA3221 is a high-power Class D amplifier that can achieve high-efficiency operation in full power, idle and standby states. The device uses closed-loop feedback with a bandwidth of up to 100kHz to provide low distortion in the audio frequency band and achieve excellent quality. The device operates with AD or low idle current HEAD (high-efficiency AD mode) modulation and can provide 2 x 105W power for a 4Ω load or 1 x 208W power for a 2Ω load. Product details: All parts and components of this product are original products, unpretentious and pure in quality; the use of high-quality original parts not only guarantees safety and quality, but also has a long service life, and more importantly, it is a strong guarantee that the actual performance can reach the design goals. * Use original TPA3221 * The main filter electrolytic capacitor adopts the imported famous brand Erkang with a capacity of 2200UF/35V*4 to ensure strong and continuous power support. * The resistors are high-precision chip resistors to ensure a good signal-to-noise ratio of the whole machine. * Adopt the special magnetic ring inductor for audio to ensure the sound is clear and powerful. * The PCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, and full tinning process to ensure good passing performance of large and small currents. First-class PCB quality.
