Forum Post: PCM5121; When in VREF mode, the problem in the case of the decoupling capacitor is connected to GND.

Hi, My customer intend to use the PCM5121 DAC in VREF mode, I2C mode, audio signal will be fed in using I2S. When in VREF mode, VCOM-pin(10-pin) is connected to a decoupling capacitor to AGND. If this still is mass production, do you think what problems happen? Best regards, Hiroaki Masumoto
