Ok, I think I have it figured out, or at least how to figure out if the converter is a master, slave, or configurable.

Sorry I have not responded sooner. I didn't know that there was I2C master and slave.
In the audio converter projects I worked on the distinction was not made. I guess these were purpose built devices so there was no need to point it out.

As I understand - the master controls the clock and initiates the transfer(?). If that is correct than it seems to me that a DAC would require and I2C master and an I2C slave for an ADC. Is that correct?

I'm an Analog Design Engineer and somewhat inexperienced with USB bridges.
I am looking for a USB to I2C bridge for audio converter applications. I'm looking for at least USB 2.0, 24 bit, 48k sample rate - more bit depth and higher sample rates preferred.
How do you determine bit depth and sample rate from typical USB bridge specs?

Searches have turned up the FT201X and the FT90X. Are either of these viable? The FT90X looks like a much higher performing part but maybe something better suited for the more experienced?

Some guidance would be great!

Thank you,

My name is Lucas. I am an Analog Design Engineer so most of this stuff is pretty foreign to me.
My primary interest with FDTI is finding a suitable USB-to-I2C bridge for use with audio converters.

I did see the FT201X but so far have not seen any reference to use for audio.
I also saw the FT90X. Looks like quite a learning curve there but I still need to do some reading.

Anyways...just thought I would say hello. So, hello.
