Other Parts Discussed in Thread: TPA3251
I remember seeing in the past an App. note or design change note about a minor discrepency in the input grounding scheme of the 3255 evaluation board. Can anyone point me to it? Stupid me I cannot find it.

Hello Eric,
Are you referring to TPA32xx Analog Input Grounding application note (SLAA719)?
All the best,
Carolina
Thanks Caro, but no I am remembering something else. It entailed having to cut trace(s) and add jumpers. Perhaps it was with a lesser powered amp (tpa3251) but would apply to the 3255 eval board also. I will find it again. Unless of course it has been removed by T.I.

Hi Eric,
Have you met any problem on the input trace design? I think you should be good as long as following the guide lines on datasheet. There are some jumpers on the EVM to select the input path because EVM is designed to cover as many applications as possible for user convenience. Thanks!
Regards,
Sam
