TPA3255-Q1: Do I need to add a resistor before input of TPA3255 to protect input from open circuit?

Part Number: TPA3255-Q1
Other Parts Discussed in Thread: TPA3255

Hi Expert,

I am using TPA3255. I find there are a lot of protection for Power supply and output, but I did not find protection for TPA3255 input.

So how can TPA3255 protect input from short or open circuit? Do I need to add a resistor before input of TPA3255 to protect input from open circuit? 

Thank you!
