I am currently redesigning the plate amp in my HT sub, as the volume/xover display thingo doesnt work and I want to get rid of all equalisation and let the 5.1 reciever do it all. I am going to reuse the chip amp (part no. TDA7296) and associated componentry as much as possible, but have hit a slight snag, being the poor quality of PCB layout diagram in the datasheets. I have cleaned up the layout as much as possible, ready for a CAD layout to be drawn, but am uncertain of a few points (circled in green), namely the connection to pin 2 on the chip amp itself, and the ground plane connection under C6. Anyone able to clarify this for me? I have included my drawing, the drawing supplied with the data sheet and the schematic. Have fun! Click to view full-sized image! Click to view full-sized image!
