hi there , I want use TPA6111A2 for one of my projects ,but anomalies were found in the EVM schematic 

in this schematic the R5 80K as in1's feedback ,but In2's feedback is 82K, does this have a special purpose? or it was just mislabeled?

    您好，

    非常感谢您的反馈，这里应该是打字错误，R5是82KΩ，从下面BOM表中可以看出R1、R4和R5都是82KΩ。

    很抱歉对您造成了疑惑！我会反馈给相关负责人对上述错误进行修改的。

    罗工 非常感谢您的确认，tpa6111a2的datasheet 也似乎存在问题，例如：5V 32Ω load，Po=20mW, THD+N 这项数据似乎应该是0.2%，我们还没有测试完，所以还不能够确定。
