Hi, Jim,
Some questions about this noise issue. Could the customer verify if the noise level can also be measured at the power supplies pins? Are there more devices on the board with this noise problem?
Best regards,

Hi, Jim,
Thank you for providing additional information on this.
Do you know if the power supplies of the TL972 have ripple or noise issues? I mean, could the customer try to increase the power pins capacitance? In addition, could the customer try to remove the output capacitors C320 and C321?
Please let me know if he has additional observations on this.
Best regards,
Luis Fernando Rodríguez S.
