I have a question about the AD5246.How long will it take for the AD5246 to start I2C communication at the shortest time after power supply VDD rises?I write the resistance value by I2C communication.
The data that you are asking is not characterized in the datasheet.
As the minimum supply for AD5246 is 2.7V, to be on the safer side the user can wait for 10us after the supply reaches 2.7V and then they can start writing in to the part.
Someone is looking at this thread and will respond to you soon. Thanks.
It Depends in the ramo rate if the supply. Once the Power-on Reset come up, AD5246 will be ready to accept the I2C commands.
Thank you for answering.

I see.But… How can the user know the end of the power-on reset?More specifically, how many seconds should the MCU wait after start up and running?
Your answer is what my customers and myself were just asking for.I will tell the customer, along with the fact that it is not a value specified in the datasheet.Thank you very much.
