Hi,
There are plenty of TPA3255 BTL amps available but 4 channel amps are almost non-existent.
As per the app note, the schematic of both 2 channel BTL and 4 channel single ended are different, but the BTL amp is completely differential, it looks like if we separate the differential input to single ended stereo input then we may get two separate outputs instead of 1 BTL output. If, this is the case, its easy to convert stereo BTL boards to 4 channel ones. I mean, INPUT_A goes to OUT_A and INPUT_B goes to OUT_B. Can somebody please tell me why its not a good idea?
Thanks,
Warm Regards,
