TAS5805M: DSP Memory Map

Part Number: TAS5805M


Hi team,

In the appendix of the following linked document, the following screenshot table contains the description of the register:

TAS5805M Process Flows:https://www.ti.com.cn/cn/lit/an/sloa263a/sloa263a.pdf

But I don't know how the unit is calculated. One of our customers asked this question.

For example, the default value of volume is 0x00800000, which is 0dB according to the software, but how to calculate it? There is a table that says 4 / 9.23. The 4 represents the number of bytes in this register. What does 9.23 mean?

Best Regards,

Amy Luo
