Other Parts Discussed in Thread: TPA3250, TPA3245EVM, TPA3245, TPA3251
I have (2) questions regarding the TPA3250D2EVM
1. Can you provide an alternate p/n for L2, L3, L4, L5 ( Coilcraft p/n MA5172-AE)? Specifically, I am looking for an inductor that is shielded and more compact.
2. The output AC coupling caps (C21,C34,C42,C56) have the option to be shorted with a jumper. Is the output AC coupling capacitor optional or is the shorting jumper present for possibly relocating the AC coupling capacitor to another location? The TPA3250 data sheet circuit connection diagram (section 10.2.4) does not show an output AC coupling capacitor. I am trying to determine if the output AC coupling capacitor is required for the TPA3250 to achieve optimal performance.
