Part Number: ADS8361

Hello guys,

One of my customers is considering using ADS8361 for their new products.
At this moment, they have the following questions Could you please give me your reply?

Q1. Is there any requirement for power up and down sequence of AVDD and BVDD pin?

Q2. When +5V is supplied to AVDD pin and BVDD is not supplied any power, how much is the current which follows from AVDD pin to BVDD pin?

Q3. In same situation as Q2, what is the voltage which appeared on BVDD pin?

Your reply would be much appreciated.

Best regards,
Kazuya.

Hi Kazuya,

There is no special power sequencing required for the ADS8361. For Q2 and Q3, we don't have any specific detail on hand to provide, may we ask what your concern here is? If we need to look into this for you, it would be best to understand what potential issues you are trying to avoid/account for.
