Jolooyo TPA3255 Four-Channel High-Power Digital Class D Power Amplifier Board

Description

• 1. Using original imported TPA3255 chip
• 2. The main filter electrolytic capacitor adopts a capacity of 470UF/50V*4 to ensure strong and continuous power support.
• 3. High-precision chip resistors are used for the resistors, which ensures a good signal-to-noise ratio of the whole machine.
• 4. Adopt audio-specific inductors to ensure clear and powerful sound.
• 5. The PCB adopts 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and full tin spraying process to ensure good passing performance of large and small currents.
