Hi,

Customer want to tune their speaker's EQ by adjusting the EQ of the audio amplifier，TAS5828M, TAS5822M could be fit for the application, but still some questions. 

  1. TAS5828M和TAS5822M内置DSP的EQ调节能力怎样？有相应的对比参数表吗？What's the adjustment range of the EQ for the integrated DSP, do you have comparison for these two devices?
  2. TAS5828M和5822M的 EQ调节范围都是全频段的吗？    Could the EQ adjustment cover the full freq range?
  3. TAS5828M和5822M的 EQ调节可以做到几阶调制？        How many levels modulation can be done through the EQ? 
  4. 这两款芯片的EQ调节的具体参数可以开放给我们通过I2C配置吗？Could the EQ adjustment be opened for customer to configure by I2C?

Regards,

Zach

    Hi Zach.

    About your questions:

    1. What's the adjustment range of the EQ for the integrated DSP, do you have comparison for these two devices?

    A: TAS5822M's EQ is the same as TAS5828M's.

    2. Could the EQ adjustment cover the full freq range?

    A: The range of EQ is from 1Hz to 48kHz(96k sample rate) or from 1Hz to 24kHz(48k sample rate).

    3. How many levels modulation can be done through the EQ? 

    A: You can take PPC3's different process flow as a reference.

    4. Could the EQ adjustment be opened for customer to configure by I2C?

    A: We're ongoing organize related documents. If you really need, you can send your request to my email(wei-qiu@ti.com) and I can send the draft version to you as a reference.

    BR.
