TPA3106D1: Maximum input range

Part Number: TPA3106D1

Hi Team,

Posting on behalf of our customer. He wants to know the acceptable input range for TPA3106D1. We have seen the post below and we want to ask for clarifications.

https://e2e.ti.com/support/audio/f/6/t/601186?TPA3106D1-Input-level-for-TPA3106-and-VREG

Customer is using a single-ended input with a 12V supply and the gain can either be 26dB or 36dB (GAIN0=1, GAIN1 selectable). What would be the maximum input voltage for this application? At max gain (36dB), would there only be ~190mV below VREG before output clipping? Does this mean the input should be limited to this value?

Thank you very much in advance.


Kind Regards,

Jejomar
