I2C communication with USB 8451

[krtiruth]

I am measuring capacitance using AD7746. I have 10 such CDC's connected through two PCA9547 multiplexers(to avoid address conflict). Can I use USB8451 to collect data instead of a microcontroller. Also Is there is another DAQ with 2 wire I2C communication or is this the only one with I2C.  Also is there some part with 10 I2C channels so I can collect data without using the multiplexer which adds complexity to code.

hello krtiruth,
If I understand your question correctly, you would like to know if the USB-8451 is a good choice for your particular chip( AD7746). As long as your chips allowing for different addressing, for you 10 different addresses, the 8451 can be connected to all the chips at once, an address each one individually through their particular address.This should allow you to not need the multiplexers to distribute communication to your various chips. As of right now the USB-8451 is the only I^2C device that National Instruments sells.  Thanks again and have a great day!
