Dear TI Team,
How much voltage can be allowed to INL/INR in max input?
This information is needed to decide audio level diagram.

Hi, Matsuda,
The INL and INR inputs cannot be higher than VDD. Otherwise, they could cause a device damage.

Hi Luis-san,
Thank you for your answer.
From device safety point of view, I understood your answer.
From headphone amp's performance point of view(THD etc), How much voltage can be allowed to INL/INR in max input?

Hi, Matsuda,
The THD level uses to increase when the maximum voltage is reached, having clipping issues. In this device, you should see a lower audio performance if the audio signal peaks are near of GND and VDD levels.
