I'm working on a new board with ADC7181C, but i'm not able to communicate via I2C.
So, I have checked everything around the chip:
- chip orientation
- pull-up resistors value on I2C lines
- CAD implementation
- supplies values and stability
- the reset pin is held low during power up sequence
- no I2C access after the reset pin is released
My doubt is there is any power sequence that must be implemented?
Thank you for any help
