Hello,
In the TAS2505 Application Reference Guide, Section 2.8.1.2.1 Standby mode, "all other blocks" is referring to IOVDD.
It is safe to connect/disconnect IOVDD while AVDD/DVDD/SPKVDD are on. Are you generating AVDD/DVDD externally or through the internal LDO?
It is okay to keep SCL and SDA pulled up with IOVDD, even if it is not powered on as shown in Figure 1-3.
Are you using DOUT? If not, it can be left floating.
All the best,
Carolina Gomez
hello
It is not an internal LDO.
Does pin processing change depending on whether it is an internal LDO or not?
Best Regards,
Hello,
I was asking if you were providing the AVDD/DVDD with the internal LDO because if you do then AVDD/DVDD are powered on at the same time as SPKVDD.
The pin processing does not depend on the internal LDO.
