Part Number: TLV320DAC3101

Hello,

 

I would like to ask to one question for the power of TLV320DAC3101.

 

Question:

Are the rise and fall time of each power supplies specified?

In our project, each power are as follows.

 

DVDD: 1.8[V]

IOVDD, AVDD, SPRVDD, SPLVDD: 3.3[V]

 

Best regards,

    Hi,

    Welcome to E2E and thank you for your interest in our products!

    The TLV320DAC3101 is tolerant to power supply sequences and times. There's no restrictions for the rise and fall times for the power supplies. However, we recommend to power up the power supplies as stated in the section 6.3.1 of datasheet:

    http://www.ti.com/lit/ds/symlink/tlv320dac3101.pdf#page=19

    This power sequence will ensure that the device is powered up and initialized correctly.

    Please let me know if you have additional questions or comments.

    Best regards,
