Part Number: TAS5782M
Hello
My customer chosen TAS5782M using Hybrid flow 1 ( fs=98KHz).
I'm sorry it may be so basic question, but master volume indicates red circle and also
orange portion in the attached file is same ? and those are 0x3D and 0x3E??
As per my customer , volume ( 0x 3D, 0x3E) in their ES board woks as after DRC, not before DRC...
I'm sorry such a fundamental question, but Please let us know.
Best Regards
Hi Kanji,
I usually call P0-R61 and P0-R62 hardware volume. However, the volume control in PPC3 has nothing to do with these two registers. As you may know, there is a software volume block in each TAS5782M flow. The same volume block exists in Flow 1 as well. See the following screenshot. This volume is before DRC and AGL.

Dear Andy san
Thank you for your reply so quickly !!
Q1
As your comment P0-R61, P0-R62, my customeris using those ( 0x3D and 0x3E) also.
Is P0-R61 and P0-R62 is output volume and after DRC ?
The portion is in attached ( output volume?)?
Q2
I am sorry that I don't know software volume in TAS5782M well.
Would you please let me know what is the register number of your screen shot
and how to use about it?
(Do you have any app note or e2e post ?)
Thank you and with my best regards
Hi Kanji,
See my comments below.
Q1) The hardware volume (P0-R61 and P0-R62) exists after the TAS5782M flow, which means it is after the DRC if the flow has a DRC.
Q2) You can find the register descriptions on Page 50 of the this app note (www.ti.com/.../slaa737b.pdf).
