Hi,
The decoupling capacitors which you recommend are mentioned on page 15 of TAS5538 data sheet for VR_DIG and VR_PWM as below.
However, the decoupling capacitors which are mounted on the evm is not same value for VR_DIG as below.
Could you please tell us the min/max value for the decoupling capacitors of VR_DIG and VR_PWM ?
Best regards,
Kato
