IRS2092 Class D Digital Amplifier Board 200W D Type DIY Stereo Amp Module Description: Use IRS2092, IRFI4019. The volume is very small and the power is large. The main circuit of the electrolytic is adopted, and the main filter adopts the capacity of 330UF/100Vx2 to ensure strong and continuous . The resistor uses 0805 0603 high-precision chip resistor to ensure a good to-noise ratio of the whole machine. The PCB adopts 1.6mm thick double-sided sheet, 2.0 copper thickness, and the whole process of tin-spraying ensures the good passing performance of the current. First-class PCB quality. The 20A high current shielding inductor is used to ensure the sound is crisp and powerful. Specifications: Working method: Class D Quiescent current: 20mA Work efficiency: 90 percent Rated output power: 200W Frequency response: 20Hz to 20KHz Working voltage: -30V to -60V Recommended power supply voltage: -50V Maximum output current: 8A Package Includes: 1 Piece IRS2092 Stereo Amp Board
