Other Parts Discussed in Thread: TAS6424, TAS6424E
My customer connected to pcm6340 after TAS6424, and the audio signal of TAS6424 included in pcm6340 has obvious background noise. Currently, they have found that 2.11MHz PWM wave and 128KHz sine wave can be measured on the inductors of the four analog output backend of TAS6424. Is this phenomenon normal?
