I'm building a TPA3251 based board with 3 outputs (1xBTL + 2xSE) and I'm not sure if I designed the input correctly. I followed the EVM documentation but I would like a second opinion.
2.2 BTL MODE (Three-Speaker Output)
OUTC and OUTD are the SE output channels and OUTA and OUTB are the BTL channels for 2.1operations. OUTC and OUTD can only be in DIFF input mode.
