Hello,
I am using ISO7641FM digital isolator in one of my project for I2C communiction between Adc output and Micro controller. but it is not communicating with micro controller.
Please suggest the solution
Thanks & Regards

Hi Dhiren,
Thanks for your interest in ISO7641FM. The device ISO7641FM is a digital isolator with unidirectional channels while I2C requires bidirectional channels. Hence, you will not be able to communicate to an I2C device using ISO7641FM directly. You would require an I2C isolator to be able to isolate I2C interface and still have communication.
ISO1540 (for multi-master interface) and ISO1541 (for single-master interface) are the I2C isolators that we have to offer. You can choose either of the devices based on whether you have one master or more than one master in your I2C bus. Thanks.
