TAS5719: Writing EQ setting to TAS5719

Part Number: TAS5719
Other Parts Discussed in Thread: TAS5713, TAS5733

Hi team,

After tuning the EQ of TAS5719 in my customer system, they would like to write the data into the device in their production. Would like to verfiy the sequence and what register is needed to write:

In their original setting, they didn't write X1B.

1. In their original FW setting, they didn't write X1B to TAS5719. Do they need to add this 0x1B = 00 into their code?

2. In their original FW setting, they write 0x07 to 0x3FF (mute) first (first line), follow by the rest of the register (EQ data). In our .cfg file, it is in the last line. Is there any differences to write it first, or last, or doesn't matter?

  • Hi,

    0x1B internal osc trim is necessary during the initialization as below. It's also suggested to leave 50ms delay after osc trim.

    As for Mute control, it's flexible configuration. Our initial script includes start / end MUTE script to avoid unexpected voice during configuration. So only UNMUTE command is needed at the end. 

    You can refer TAS5733 datasheet 8.2.1.2.5 recommended startup and shutdown sequence.

    Regards,
