TAS2552: Is AVDD required when no audio input is used

Part Number: TAS2552

If audio input is not used and shorted together, is AVDD supply still required?

Thanks,

Allan

  • Hi Allan,

    Welcome to e2e.
    By audio input you mean analog input?
    AVDD is required even if only digital input is used. AVDD powers more than the analog path inside the device.
