Hello, when we set to "101", we found the current consumption increase(300mA) compare to the default setting, and TAS6424E itself become very hot, what's the reason? thanks!

Hello, you‘d better set the register settings while in Standby mode. Have TAS6424 entered the standby mode when you changed the register setting?
And attention should be paid that Bit 5 must be set to '1' before the device exits STANDBY.
That is to say, Standby mode and bit5 =1 at 0x28
Hello, we setting the register follow your instruction, then i measure the output by audio precision, the result as below show: do we setting successfully? it seems have some problem, the output waveform same as before we not setting the register, would you pls give advise? thanks! and the current still become high.
您好,为了方便沟通,我们可以直接使用中文。
您的问题是当输出相位调节之后,功耗增加,现在功耗问题解决了是吗?
目前您的问题是,改变相位之后,发现和原来波形相位相同,并未发生改变,是这个意思吗?
谢谢!我的意思是功耗还是增加的,并且也没有看到任何的波形相位改变和以前设置之前的相比,这样的话是没有设置成功吗?设置的时候需要注意什么?有设置的步骤说明吗?谢谢!
有尝试读取这个output phase寄存器的值确认是否已经写入进去?
配置的方法如下:
1. Standby mode and bit5 =1 at 0x28
2. Setting lower 2bit xx is for 1-0bit of Miscellaneous Control 2 Register
在配置完I2C的寄存器之后可以退出standby mode。
另外,TAS6424是一款数字I2S /TDM输入,PWM输出,从您的波形来看,输入是模拟信号呢?
Hi, 我测试的波形是输出端,经过LC滤波后的,你的意思是需要直接测试LC滤波电路前面的PWM信号吗?输入我们使用的是TDM4, controller 内部产生的1KHz的正弦波输出到TAS6424E,谢谢!
抱歉回复晚了。是的我的意思是直接测量芯片输出端。
你好,我测试了设置phase out前与设置后的输出波形,如下所示,设置前后的输出频率发生了变化,这个有可能是原因导致的?谢谢!
设置前,2.1MHz
设置后,384KHz
您好,您的意思是设置phase out寄存器后,输出频率发生变化了是么?
如果不设置phase out,频率发生改变吗?
