TPA3116D2-Q1: Choosing correct power amplifier module - similar modules

Part Number: TPA3116D2-Q1
Other Parts Discussed in Thread: TPA3126D2, TPA3116D2

Please delete this post if it is not appropriate however I wanted some help with choosing the correct power amplifier.

The requirements were as follows:

  • Up to 50W per channel for a stereo power amplifier
  • Load: 4-16Ohms

I was mostly looking at the TPA3116 just because it is commonly used however it is not a good enough reason to choose it. Having said that all the devices listed below seem to be similar to me - perhaps can anyone shed some light on their differences please?

Thank you in advance,
