说明

The TPA3122D2 is a 15-W (per channel) efficient, Class-D audio power amplifier for driving stereo single ended speakers or mono bridge tied load. The TPA3122D2 can drive stereo speakers as low as 4. The efficiency of the TPA3122D2 eliminates the need for an external heat sink when playing music.

The gain of the amplifier is controlled by two gain select pins. The gain selections are 20, 26, 32, and 36 dB.

有板吗？感兴趣哦

本人曾在TI网站免费申请过5片样片，自己Layout,做了一块感觉各方面都优于TDA2030，LM1875等小功率放大器
