Hi All,

Do TLV320DAC3203  AVDD（3.3V）and DVDD(1.8V)  have a require of power-up timing ? And what is the difference between different power-on timing?

    Hi, Allen,

    The TLV320DAC3203 has a strong tolerance against the power up sequences. We just recommend to ensure that each power supply is stable before enabling the next power supply. There's no difference between the different power-on timing.

    If you are using AVDD = 3.3V and DVDD = 1.8V, you just need to wait unit AVDD = 3.3V before powering up DVDD.

    Best regards,
