Carte d'amplificateur numérique TPA3250 130 W x 2, amplificateur audio haute puissance 4 A 32 V de classe D avec câble blindé XH2,54 mm-3P kns

1. Using imported TPA3250 2. The main circuit of the electrolytic capacitor signal adopts a chip electrolytic capacitor with a capacity of 4*220UF, which ensures a strong and continuous power support. 3. The resistors use high-precision chip resistors to ensure a good signal-to-noise ratio of the whole machine. 4. The PCB adopts 1.6m thick double-sided sheet, 2.0 oz copper thickness, and the whole process of spraying tin to ensure good passing performance of large and small currents. Top-notch PCB quality. 5. Fully shielded high-current inductors are used to ensure clear and powerful sound.

The TPA3250 device is a high-performance Class-D power amplifier that delivers true high-quality sound with Class-D efficiency. The device features an advanced integrated feedback design and proprietary high-speed gate driver error correction (Purepath Ultra-HD). This technology enables ultra-low distortion and superior audio quality in the audio frequency band. The device operates from a 32V supply Power supply, can provide up to 2W*130W peak drive to 4ohm load, or 2W*70W continuous drive to 8ohm load, and has 2 VRMS analog input interface, which can be seamlessly matched with high-performance DACs such as TI PCM5242. Audio performance, the TPA3250 also achieves high power efficiency and power stage no-load power dissipation below 1 W. This is achieved by using 60 mohm MOSFETs and an optimized gate driver scheme with much lower no-load losses than typical discrete devices. How it works: Class D Quiescent current: 50mA Work efficiency: 90% Rated output power: 2x130W Frequency Response: 20Hz to 20KHz Working voltage: D18V to Dc32V Maximum output current: 4A Product size: length 103 x width 78 x height 15MM Cable length: 30cm Cable terminal specification: XH2.54mm-3P Colour:black Material:PCB+Metal
