We are a group of students working on a project for our university. We have encountered some issue with the AD5593RBRUZ, which we wish to use as an A/D converter. It seems that every register we attempt to read from using I2C returns the sixteen bit word 0x03FC. Furthermore, our writes seem to be having no effect. We have confirmed that I2C communication is operating as expected using a high speed oscilloscope. Furthermore, the clock frequency is the standard stated in the datasheet (100kHz). Resetting using the available pin, as well as using the software command is not working either. Any help or feedback would be greatly appreciated.
