I would like to use AD7995.
So, I have a question.
Data is transferred by pulling up VDD at 4 V and SCL / SDA at 3.3 V.
In this case, does the SCL / SDA start running after the 4 V power supply rises to 3.3 V?
The AD7995 is controlled using I2C interface. after power up, then digital lines can have a signal. You can check page 22 of the datasheet about the serial interface of the AD7995. The AD7995 can be powered up with Vdd from 2.7V to 5.5V supply.
Thank you very much!
