配置I2S信号输入为“out, L/R, 16 bits lsbj”和“out, L/R, 18 bits lsbj”
扬声器充满噪音
ma12070p 不支持这种格式吗?
我用它默认的power输入格式(如下图)
如何在没有单片机的情况下正确配置格式?谢谢

MA12070P默认I2S格式是left justified 32bit, 可以通过I2C配置需要的I2S格式。如果设计没问题功率太大过温保护,那么需要考虑加强散热

输入I2S跟MA12070P设置的I2S格式要一致。MA12070P默认是 left justified 32bit。 可以通过I2C配置需要的I2S格式。格式不对不能正常工作.

got it,
The chip can only support 32-bit left aligned format, right?
Another question:
I use cs8412s to output 24 bit IIS to 12070p
I have configured I2S mode. If the sound is louder, there will be intermittent pause and overheating protection,
Thank you for your help!
