TPA3221 is a high-power class-D amplifier with closed-loop negative feedback with a bandwidth of up to 100kHz, providing low distortion of the audio band and excellent audio quality. The device works in AD or low no-load current HEAD (high efficiency AD mode) modulation, and can Ohm load provides 2x105W.
1. Using Beijing 6J1 electronic tube, can replace the tube: 6K4, 6J2, GE5654, 6J3, 6J4, 6J5, 6*1N, 6AK5, etc.
2. Original TPA3221 Class D amplifier chip.
3. Op-amp chip LM4562NA
4. The main filter capacitor adopts imported 1000UF/50V
5. High-precision chip resistors are selected for the resistors to ensure a good signal-to-noise ratio of the whole machine.
6. The PCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, and the whole process of spraying tin to ensure good passing performance of large and small currents. First-class PCB quality.
