I am making a board that has the ADT7420 on it.
I want it to be the slave device my master device to be many meters away.
- Where do I put the pullup resistors? On the master or slave board?
- For the CT and INT pins are the pullups optional?
- If not, is it best to put their pull ups on a master or slave board?
- For decoupling many meters away should I have a low pass filter?
- For the i2C communication pins could I have resistor terminations for the wires that are up to a meter away? Will that interfere with the pullups?
