Product description:
TPA3221 Bluetooth 5.0 QCC3034 digital power amplifier
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. Provide 210W for 2 ohm load
Features:
1. Using original imported TPA3221 digital chip
2. The main filter capacitor adopts imported 1800UF
3. High-precision chip resistors are selected for the resistors to ensure a good signal-to-noise ratio of the whole machine.
4. 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.
5. The input and output use gold-plated RCA lotus seat, durable and beautiful!
6. The board wiring is reasonable, beautiful, and low noise
7. Bluetooth uses Qualcomm QCC3034 module to support sbc, aac, aptx, aptx-HD
8. Bluetooth DAC uses PCM5102 to decode independently
