Description:

TPA3221 is a high-power class D amplifier that can achieve high efficiency in full power, idle and standby states. The device uses closed-loop feedback with a bandwidth of up to 100kHz to provide low distortion in the o frequency band and achieve excellent quality. The device operates with AD or low idle current HEAD (high-efficiency AD mode) modulation and can provide 2 x 105W power for a 4 ohm load or 1 x 208W power for a 2 ohm load.
The main filter electrolytic capacitor adopts the imported famous brand Erkang with a capacity of 2200UF/35V*4 to ensure strong and continuous power support.
High-precision chip resistors are selected for the resistors to ensure a good signal-to-noise ratio of the whole machine.
Adopt special netic ring inductor for o to ensure the sound is clear and powerful.

Features:

1. Use original TPA3221
2. High-precision chip resistors are selected for the resistors to ensure a good signal-to-noise ratio of the whole machine.
3. Adopt special magnetic ring inductor for audio to ensure the sound is clear and powerful.
4. The PCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, and full tin spraying process to ensure good passing performance of large and small currents.
