the AD5933 evaluation boards illustrates the AD5933BRSZ, where pin 1 to 3 are labelled as
Pin 2 and 3 are driven by the micro-controller. Yet the datasheet refers to pin 1 to 3 as not connected. Is the device on the evaluation board specific, or is the information in the datasheet not up-to-date with the chip revision ?
I'm designing a measurement system where I would like to use two devices, having a CS would greatly help solving the issues about having two devices on the same I2C bus.
