Are there any known problems when expanding from 4 channels to 8 channels by using two FDC1004 on the same I2C bus?

Hi Cameron:

We currently do not have any known problems. We have not done any extensive testing with two FDC1004's on the same I2C bus. It is possible to use an I2C switch to send individual commands to either of the FDC1004's. What is your application?

Thanks

Just need more than 4 channels to do some automated testing. Thanks for your input.
