My customer is asking the following:
My question is when the TPA3255 is configured as a 4 channel single ended output can you still combine channels 1&2 and channels 3&4 by using the "hot" positive ends essentially converting your 4 channel se configured output to a 2 channel BTL configured output post internal configuration. From what I can tell in your documentation of the TPA3255 it looks like this is possible but wanted to confirm.
I could not find this type configuration in the data sheet, but I believe that this will work. Can you confirm? I can send you the pdf that he attached if you need to see it.
Do we have an application note that explains all of the possible audio speaker configurations? When the customer starts asking these questions I sometimes do not understand the configuration that he mentions. I understand the basic modes of operation, but if we have some type of application note it would help me to be able to answer the questions I receive.
Thanks for your help with this!
