Hi
I am tryin gto understand the bridged class AB concept used in TPA0211 audio amp. from Texas. This amp has 2 class AB amplifiers which can be bridged together so that the maximum voltage on load can be as much as 2xSupply without the need for negative supply and without generating neg. supply internal. Now, I can understand that it must be like this or with other words, I accept it must be like this but I cant explain it theoreticaly since I am no expert with class AB theory. I tried to find some recourses on net and at Texas and found the reason for this behaviour is caused by an inverter follower but this is somewath new to me and I need to find some recourses explaining the teory. Please help me out
Thanks in advance
