Other Parts Discussed in Thread: TPA2000D1
dear TI:
I'm currently evaluating the TPA2000D1 amplifier in an audio application similar to smartphone.now I'm having issues with some noise coming out of the TPA2000D1.
the noise interferes with all the signal lines,such as power,GNDI,/O.As long as I enable PA, the noise will occur. The frequency of noise is about 500K.I think it was produced by ROSC pin.
Anybody got any idea why I have this noise and how can I remove it?
following picture1 is the nosie on VDD, picture2 is schematic.
thanks!
